Travel behavior

"Transit ridership fell in 31 of 35 major metropolitan areas in the United States last year, including the seven cities that serve the majority of riders, with losses largely stemming from buses but punctuated by reliability issues on systems such as Metro, according to an annual overview of public transit usage."

Is Paris in the position to be able to offer free transit to all? This article breaks down the barriers and examines how it has become reality in other cities.

Automated vehicle (AV) policy development and assessment is a difficult and complicated process. Today’s road and vehicle policies are the product of a hundred years of lessons learned. They generally address five areas: safety, efficiency, mobility, convenience, and impact on the environment. Now the prospect-turned-reality of automated vehicles entering public roadways has opened up a number of new policy-related questions. Is it enough to simply modify current road and vehicle policies or will new policies need to be developed addressing much broader aspects of the transportation system? How can these policies be developed to accommodate technologies that either do not yet exist or are only now being tested on the road in constrained environments? Perhaps most importantly, how can policy influence technological design to safely operate with other road users and can we look ahead to have a better view of potential unintended consequences?

"In response to the Trump administration’s withdrawal of support for the international Paris Climate Agreement last year, the City Council adopted Resolution 31757, affirming Seattle's commitment to the goals established in the Paris Agreement, and directing the Office of Sustainability & Environment (OSE) to identify the actions necessary to do our part to limit warming to 1.5 degrees Celsius. The resulting actions, developed under the leadership of Mayor Durkan, reflect a tipping point in the transition to Seattle’s zero emissions future. They are designed to move beyond incremental change and fundamentally reshape our building and transportation systems for a fossil fuel-free future."

We quantify the importance of early action to tackle urban sprawl. We focus on the long-term nature of infrastructure decisions, specifically local roadways, which can lock in greenhouse gas emissions for decades to come. The location and interconnectedness of local roadways form a near permanent backbone for the future layout of land parcels, buildings, and transportation options. We provide new estimates of the environmental impact of low-connectivity roads, characterized by cul-de-sacs and T-intersections, which we dub street-network sprawl. We find an elasticity of vehicle ownership with respect to street connectivity of –0.15—larger than suggested by previous research. We then apply this estimate to quantify the long-term emissions implications of alternative scenarios for street-network sprawl. On current trends alone, we project vehicle travel and emissions to fall by ∼3.2% over the 2015–2050 period, compared to a scenario where sprawl plateaus at its 1994 peak. Concerted policy efforts to increase street connectivity could more than triple these reductions to ∼8.8% by 2050. Longer-term reductions over the 2050–2100 period are more speculative, but could be more than 50% greater than those achieved by 2050. The longer the timescale over which mitigation efforts are considered, the more important it becomes to address the physical form of the built environment.

"In this paper we propose a new method to study how replacing privately owned conventional vehicles with automated ones affects traffic delays and parking demand in a city. The model solves what we designate as the User Optimum Privately Owned Automated Vehicles Assignment Problem (UO-POAVAP), which dynamically assigns family trips in their automated vehicles in an urban road network from a user equilibrium perspective where, in equilibrium, households with similar trips should have similar transport costs.

This Electric Vehicle Strategy focuses on electrification of the public transit system, shared vehicles and the private automobiles that remain in use, which is one of many strategies the City is taking to reduce carbon emissions from the transportation sector. This strategy also seeks to maximize the benefits of air quality and affordability for low-income residents and parts of Portland that are the most dependent on private vehicles.

"Our City of the Future: Technology and Mobility report is meant to help city leaders understand, imagine and plan for the coming changes in the urban environment that will affect how we all move from one place to another."

The survey results described here provide a new window into ride-hailing utilization in the Boston Region. Our findings confirm many widespread assumptions about ride-hailing, but also provide new insights into previously unexplored and unmeasured topics. Ride-hailing is used by a wide variety of Metro Boston residents, and riders are relatively representative of the region in terms of race and income.

This document provides background on micromobility and what it is, answers the question "Who uses shared micromobility?" and identifies current policies and practices.

Based on the 2001 and 2009 National Household Travel Surveys, this paper analyzes trends and determinants of multimodal car use in the U.S. during a typical week by distinguishing between (1) monomodal car users who drive or ride in a car for all trips, (2) multimodal car users who drive or ride in a car and also use non-automobile modes, and (3) individuals who exclusively walk, cycle, and/or ride public transportation. We find that during a typical week a majority—almost two thirds—of Americans use a car and make at least one trip by foot, bicycle, or public transportation. One in four Americans uses a car and makes at least seven weekly trips by other modes of transportation. Results from multinomial and logistic regression analyses suggest there may be a continuum of mobility types ranging from monomodal car users to walk, bicycle, and/or public transportation only users—with multimodal car users positioned in-between the two extremes. Policy changes aimed at curtailing car use may result in movements along this spectrum with increasing multimodality for car users.

Nashville faces one of the biggest votes to date, a plan to approve or deny a $5.4 billion plan to overhaul the current transit system.

"This report summarizes the status of twenty-nine partnerships between TNCs and public bodies around the United States designed to improve mobility." The analysis explains when the programs were or are active, if they were modified, the financial structure and performance audits.

From ancient Rome to modern Atlanta, the shape of cities has been defined by the technologies that allow commuters to get to work in about 30 minutes.

This book is designed to communicate how communities of all kinds are making these changes all the time. It is our hope that this will make it easier for new projects to get built and that the examples will make it possible for a “new normal” to take hold, where all streets are revisited and assessed to see whether they can be doing more. This is similar to a post-occupancy analysis–do our streets perform the way we want given all of the needs and uses we have of them? If not, then this book provides many examples on how to move forward and ‘remodel’ our streets.

"Our primary focus is travel related energy consumption and emissions, since potential lifecycle impacts are generally smaller in magnitude. We explore the net effects of automation on emissions through several illustrative scenarios, finding that automation might plausibly reduce road transport GHG emissions and energy use by nearly half – or nearly double them – depending on which effects come to dominate."

Concerns over rising fuel prices and greenhouse-gas emissions have prompted research into the influences of built environments on travel, notably vehicle miles traveled (VMT). Accessibility to basic employment has comparatively modest effects, as do size of urbanized area, and rail-transit supplies and usage. Nevertheless, urban planning and city design should be part of any strategic effort to shrink the environmental footprint of the urban transportation sector.

The Atlanta Regional Commission (ARC) has, through scenario planning, already begun to consider the effects that emerging technologies such as AVs and accelerated broadband might have on travel patterns. This report moves another step forward. It identifies and explores transportation technology trends, their potential impacts, and their policy implications, both generally and those specific to the Atlanta region. The result is intended to help support the Atlanta region in developing a regional transportation technology program to prepare for and take advantage of technology innovations in support of the region’s goals.

A study was done to see how location to transit impacts the amount you spend on transportation in a year - this article explains the findings.

This article is a review of Adonia Lugo's book: "Bicycle / Race: Transportation, Culture, & Resistance". The book talks about issues of race and class in bicycle culture. It is a call to refocus bicycle-planning beyond physical infrastructure to include human-infrastructure that centers on the stories and identities that shape how, where, when, and why we travel.

This article briefly outline the success of upgrades made to a bus line in the Twin Cities. So far ridership has increased 30%.

"Carsharing exemplifies a growing trend towards service provision displacing ownership of capital goods. We developed a model to quantify the impact of carsharing on greenhouse gas (GHG) emissions. The study took into account different types of households and their trip characteristics. The analysis considers five factors by which carsharing can impact GHG emissions: transportation mode change, fleet vintage, vehicle optimization, more efficient drive trains within each vehicle type, and trip aggregation. Access to carsharing has already been shown to lead some users to relinquish ownership of their personal vehicle. We find that even without a reduction in vehicle-kilometers traveled the change in characteristics of the vehicles used in carsharing fleets can reduce GHGs by more than 30%. Shifting some trips to public transit provides a further 10%–20% reduction in GHGs"

Texas is one of the fastest growing states in the nation, and its growth is expected to continue, supported by diversity in its economy, geography, and population. The challenge of prioritizing limited resources in this environment requires a proactive approach to travel demand management. This project provides guidance for TxDOT in its planning and mobility efforts and in understanding the viability of various alternative mobility programs.This report describes research of best practices and lessons learned from mobility programs. The research describes executive interviews, focus groups, and surveys to obtain details and document perspectives of the varying stakeholder groups. The research produced a guidebook that will aid TxDOT in determining how to best identify and implement alternative mobility programs in a given region as part of its planning and mobility efforts.

This article outlines the changing numbers Uber has experienced this year and the sharp declining revenue. Chief executive, Dara Khosrowshahi, weighs in on the changes.

This paper evaluates the greenhouse gas (GHG) emission impacts that result from individuals participating in carsharing organizations within North America. The authors conducted an online survey with members of major carsharing organizations and evaluated the change in annual household emissions (e.g., impact) of respondents that joined carsharing. The results show that a majority of households joining carsharing are increasing their emissions by gaining access to automobiles.

This year’s report builds on that same contextual foundation with updated travel trend charts and speed maps. Since 2015, the number of residents, jobs, and annual tourists have continued to grow. Even as the City encourages and facilitates the use of high performance modes, we recognize that the demands on our ?nite street network are only growing and our roadways are frequently functioning at capacity.

This work describes the design of an agent-based model for shared autonomous vehicle (SAV) operations, the results of many case-study applications using this model, and the estimated environmental benefits of such settings, versus conventional vehicle ownership and use. Preliminary results indicate that each SAV can replace around eleven conventional vehicles, but adds up to 10% more travel distance than comparable non-SAV trips, resulting in overall beneficial emissions impacts, once fleet-efficiency changes and embodied versus in-use emissions are assessed.

This report estimates that by 2030, a substantial share of the 175 million Americans who live in the nation's largest cities will turn to SAEVs, cutting transportation costs by nearly 50%, reclaiming time instead of losing hours a day to traffic and putting up with all the expense and hassle of urban automobile ownership. SAEV fleets will account for nearly 25% of all auto passenger miles traveled in the US by 2030. Such a change will have an enormous impact on health, safety, and quality of life in cities: Traffic accidents and fatalities will be reduced by nearly two-thirds. Pollution will be drastically curtailed. Cities can repurpose millions of square feet once used for parking to new green spaces or commercial uses while securing more affordable mobility and accessibility for elderly, disabled, and low-income people.

This report, BCG's latest on AVs, examines the case for AVs as a cornerstone of the urban mobility revolution, as seen through the experience of Boston. It describes transportation challenges, strategic considerations, scenario modeling and simulations, and field testing.

This article discuss the reasons for Seattle's success in transit ridership increase in terms of transit service, mode prioritization, and traffic management.

"This paper identifies three promising applications of new mobility services by public transit agencies, and presents economic, social, and environmental modeling that illustrate the value of such partnerships to mass transit systems."

Technology is transforming transportation. The ability to conveniently request, track, and pay for trips via mobile devices is changing the way people get around and interact with cities. This report examines the relationship of public transportation to shared modes, including bikesharing, carsharing, and ridesourcing services provided by companies such as Uber and Lyft. The research included participation by seven cities: Austin, Boston, Chicago, Los Angeles, San Francisco, Seattle and Washington, DC. The objective of this research analysis is to examine these issues and explore opportunities and challenges for public transportation as they relate to technology-enabled mobility services, including suggesting ways that public transit can learn from, build upon, and interface with these new modes.

Warren Logan, a Bay Area transportation planner, has new ideas about how to truly engage diverse communities in city planning. Hint: It starts with listening.

Lawyers of a luxury condo in New York City have been brought into the debate surrounding the construction of a new bike lane that over took city parking in front of the condos.

Lyft's new Shared Saver option offers individuals cheaper rides for the price of waiting a little longer and walking a little further.

As public transit stagnates in most U.S. cities, central Seattle continued its rapid growth by adding roughly 10,000 morning transit commuters last year, new local data show.

Focus on emissions and energy efficiency has long been focused on vehicles and improving their efficiency. This article discusses the option that hasn't been utilized as much by policy markers, to just limit the amount people drive.

This paper models the market potential of a fleet of shared, autonomous, electric vehicles (SAEVs) 20 by employing a multinomial logic mode choice model in an agent-based framework and different 21 fare settings.

"AVs are already being road tested in several states and will be available for sale within five to ten years. They promise to make automobile travel safer and more efficient, and to dramatically change transportation planning and engineering. This paper assesses the most likely effect of AVs on traffic generation and highway capacity and congestion over time as AVs come to represent a greater percentage of the vehicles on the road."

This doctoral dissertation analyzes the impacts of ridesourcing on several areas of transportation including: efficiency in terms of distance Vehicles Miles Traveled (VMT) versus Passenger Miles Traveled (PMT) – and travel times, mode replacement, VMT increase, parking, transportation equity, and travel behavior.

The author presents his view of limitations of prediction and how it apply to transportation prediction such as ridership prediction. He describes the concepts for planning the future (with time and space) that always emphasize the freedom as the goal.

"This Mobility Hub Features Catalog is a resource for regional agencies, local jurisdictions, transit operators, and private service providers as they collaborate to design and implement mobility hubs around the region. It describes the kinds of services, amenities, and technologies that can work together to make it easier for people to connect to transit, while also providing them with more transportation options overall. These mobility hub features may include various transit station improvements such as enhanced waiting areas with landscaping and lighting, complimentary WiFi and real-time travel information; wider sidewalks, pedestrian lighting and trees for shade; bike paths, designated bike lanes, and bike parking options; dedicated bus lanes and supporting signal improvements; service facilities for shared cars, scooters, and electric vehicles; smart parking technology; and more. Each feature can be tailored to the unique needs of an individual community."

Chicago’s pilot electronic-scooter program is proving to be a hit with low-income residents who have few transit choices in their far-flung neighborhoods.

The Chicago metropolitan area has one of the most extensive public transit systems in the United States, yet there are many places in the region where people do not have convenient access to transit service. To address that deficiency, this paper identifies practical ways to give more travel options to people in areas that are underserved by transit, including people who are unable to own or rent a car or have physical limitations that prevent them from driving.

This paper discusses the history of shared mobility within the context of the urban transportation landscape, first in Europe and Asia, and more recently in the Americas, with a specific focus on first- and last-mile connections to public transit. The authors discuss the known impacts of shared mobility modes—carsharing, bikesharing, and ridesharing—on reducing vehicle miles/kilometers traveled (VMT/VKT), greenhouse gas (GHG) emissions, and modal splits with public transit. The future of shared mobility in the urban transportation landscape is discussed, as mobile technology and public policy continue to evolve to integrate shared mobility with public transit and future automated vehicles.

In this study, we present exploratory evidence of how “ridesourcing” services (app-based, on-demand ride services like Uber and Lyft) are used in San Francisco. We explore who uses ridesourcing and for what reasons, how the ridesourcing market compares to that of traditional taxis, and how ridesourcing impacts the use of public transit and overall vehicle travel. In spring 2014, 380 completed intercept surveys were collected from three ridesourcing “hot spots” in San Francisco. We compare survey results with matched-pair taxi trip data and results of a previous taxi user survey. We also compare travel times for ridesourcing and taxis with those for public transit.

"This white paper provides a framework and examples to assist transportation agencies in anticipating and planning for shared mobility as part of a higher-performing regional multimodal transportation system. It synthesizes noteworthy practices in 13 metropolitan areas as of spring/summer 2017 collected from online research and conversations with planning practitioners, identifies challenges and opportunities, and provides recommendations for future research needed to improve planning practices related to shared mobility."

This report gives insight to how shared mobility options can impact our cities. It gives some ideas but overall concludes that impacts will vary and more research is needed to full understand.

"This research shows that public transportation (in its current form) will only remain economically competitive where demand can be bundled to larger units. In particular, this applies to dense urban areas, where public transportation can be offered at lower prices than autonomous taxis (even if pooled) and private cars. Wherever substantial bundling is not possible, shared and pooled vehicles serve travel demand more efficiently."

"This report consists of nine chapters. Chapter 2 describes the effects of technology on transportation in general, the innovative services relevant to this report, what is known about the use of these services, and their potential impacts. Chapter 3 explains the existing regulatory structure of the taxi, sedan, and limousine industries and the challenges to that existing structure presented by the rise of TNCs. Chapter 4 presents an economic framework for address- ing those challenges. Chapters 5 through 8 then review specific issues facing shared mobility services: Chapter 5 examines labor and employment issues; Chapter 6 addresses personal security for drivers and passengers and safety for the public; Chapter 7 reviews insurance issues; and Chapter 8 looks at issues of access and equity. Chapter 9 presents the overall conclusions resulting from this study and the committee’s recommendations for policy makers and regulators who must consider whether and how to regulate these new services to serve public policy goals, and outlines research needs."

This Strategic Plan is designed to help the East-West Gateway Council of Governments (EWG) to better position itself to prepare for emerging transportation technologies in its planning and investment decision making processes.

"Automated driving technologies are currently penetrating the market, and the coming fully autonomous cars will have far-reaching, yet largely unknown, implications. A critical unknown is the impact on traveler behavior, which in turn impacts sustainability, the economy, and well-being. Most behavioral studies, to date, either focus on safety and human factors (driving simulators; test beds), assume travel behavior implications (microsimulators; network analysis), or ask about hypothetical scenarios that are unfamiliar to the subjects (stated preference studies). Here we present a different approach, which is to use a naturalistic experiment to project people into a world of self-driving cars. We mimic potential life with a privately-owned self-driving vehicle by providing 60 h of free chauffeur service for each participating household for use within a 7-day period. We seek to understand the changes in travel behavior as the subjects adjust their travel and activities during the chauffeur week when, as in a self-driving vehicle, they are explicitly relieved of the driving task. In this first pilot application, our sample consisted of 13 subjects from the San Francisco Bay area, drawn from three cohorts: millennials, families, and retirees. We tracked each subject’s travel for 3 weeks (the chauffeur week, 1 week before and 1 week after) and conducted surveys and interviews. During the chauffeur week, we observed sizable increases in vehicle-miles traveled and number of trips, with a more pronounced increase in trips made in the evening and for longer distances and a substantial proportion of “zero-occupancy” vehicle-miles traveled."

This paper presents an analysis of the data and frames it in a broader context. It concludes with a description of FTA actions that address climate change.

This paper describes research undertaken to establish plausible fuel-speed curves (FSC) for hypothetical advanced powertrain vehicles. These FSC are needed to account for the effects of congestion in long-term transportation scenario analysis considering fuel consumption and emissions. The results presented in this paper will assist analysis of the roles that vehicle technology and congestion mitigation can play in reducing fuel consumption and emissions from roadway travel.

"Ride-sharing services are transforming urban mobility by providing timely and convenient transportation to anybody, anywhere, and anytime. These services present enormous potential for positive societal impacts with respect to pollution, energy consumption, congestion, etc."

"This article intends to advance future research about the travel behavior impacts of SAVs, by identifying the characteristics of users who are likely to adopt SAV services and by eliciting willingness to pay measures for service attributes. The results show that service attributes including travel cost, travel time and waiting time may be critical determinants of the use of SAVs and the acceptance of DRS. Differences in willingness to pay for service attributes indicate that SAVs with DRS and SAVs without DRS are perceived as two distinct mobility options. The results imply that the adoption of SAVs may differ across cohorts, whereby young individuals and individuals with multimodal travel patterns may be more likely to adopt SAVs."

This article discusses the changes that will be necessary once AVs hit our streets. The changes in insurance policies, jobs, land use, etc. will change our societal norms.

A new analysis tracking the relationship between transit access and apartment rent seeks to put some numbers behind the dramatic shifts in urban mobility. The new study by RCLCO, a real estate consultancy, and TransitScreen, a company that provides real-time arrival and departure info, analyzed 40,000 apartment developments nationwide, which contained roughly 9 million units, to determine how access impacts costs in different cities and neighborhoods. Results found that improvements in access to bike-sharing and ride-hailing made a more significant difference nationally than access to traditional transit or carshare services.

The 2017 Community and Transportation Preferences Survey echoes many of the major findings from the previous surveys. Residents in the fifty top metropolitan areas continue to be split on what they look for in a neighborhood. A small majority prefer the idea of a walkable community and more alternatives to driving, but suburban living remains highly attractive to a sizable portion of the community.

Upon the roll-out of AVs into our streets, the importance of public and private sector partnerships are emphasized. With increased mobility, the demand for private rides could be increased and therefore increase congestion in our streets.

This study aims at capturing the users’ preference, while considering investors’ limitations and societal cost and benefits of each mode. The problem is defined as a mixed-integer non-liner problem, with non- linear objective function and constraints. Because of the computationally challenging nature of the problem, a metaheuristic algorithm based on simulated annealing algorithm is proposed for its solution. The performance of the algorithm is tested in this study and convergence patterns are observed.

"This study examines the potential for public e-scooter sharing systems to fill mobility needs within and between Chicago neighborhoods. It explores how availability of this micro-mode of transportation could influence travel time, cost, and the convenience of trips relative to other active and shared-use modes including walking, bicycling, bikeshare, and public transit."

The article summarizes the current scope of the e-scooter, bike and moped scene. It offers the dangers and true benefits of the programs to readers.

"This report attempts to address these questions by further exploring evidence of how TNCs are affecting the use of public transit and personal automobiles in several regions."

According to the latest statistics from the American Public Transit Association, the region has experienced a 5.7 per cent increase in the number of boardings year-over-year. Only three other urban areas with a population of more than one million saw transit ridership growth last year.

This article discusses about the cost of AV per mile compared to SOVs and looks into AV peak demand and surge pricing.

The goals of this study were to explore e-hail (e.g., Uber/Lyft) knowledge, use, reliance, and future expectations among older adults. Specifically, we aimed to identify factors that were related to e-hail, and how older adults view this mode as a potential future transportation option. Data were collected from a sample of older adults using a pencil-and-paper mailed survey. Univariate, bivariate, and regression techniques were used to assess the relationships among e-hail and several demographic and other factors. E-hail may be a viable future option for older adults who have limited or stopped driving. More exposure to e-hail and continued evolution of these services is required to overcome older adults’ lower internet/smartphone use. Policies could be implemented at departments of motor vehicles to pair information or training on transportation alternatives (like e-hail) with elimination of driving privileges, or at doctors’ offices, senior centers, or hospitals. Potential underlying reasons for the findings are also discussed.

The forces that will influence the environmental impacts of large-scale AV adoption are identified to help determine necessary future research directions. It is too early to determine which of these forces will dominate the system and dictate whether AV adoption will result in net reductions or increases in greenhouse gas (GHG) emissions. The environmental research community must develop a better understanding of the disruptive forces of AVs to help develop a strategy to reduce transportation emissions. Particular emphasis is needed regarding how AVs will be adopted and used, as these patterns may ultimately dictate the environmental impacts of AVs. Without better integration of engineering, social science, and planning disciplines to model future adoption scenarios, important opportunities to steer markets toward sustainable outcomes will be lost.

A year ago, electric rental scooters were hailed as the next big thing in transportation. But their troubles in San Diego show how the services have now hit growing pains.

As private mobility services such as car-sharing, ridehailing, and micromobility have rapidly expanded in cities, the public sector has historically had limited access to data on how these vehicles are changing travel patterns and the movement of people. Populus has launched a platform to change that.

"This paper presents findings from a comprehensive travel and residential survey deployed in seven major U.S. cities, in two phases from 2014 to 2016, with a targeted, representative sample of their urban and suburban populations. The purpose of this report is to provide early insight on the adoption of, use, and travel behavior impacts of ride-hailing. The report is structured around three primary topics, key findings of which are highlighted below."

For 50 years, American geography and land use has been centered on the personal car. The three revolutions in vehicle sharing, automation and electrification present new challenges and also great opportunities for land use and transportation planners. Absent policy reform, the three revolutions may contribute to more sprawl, but a sustainable planning approach that supports both higher-density development and lower single-occupant (or zero-occupant) driving can once again put people first rather than their cars.

"The aim of this paper is to show how TNCs could replace public transportation in the United States if subsidized at the same level of transit agencies."

"This paper advances understanding of modal shifts caused by bikesharing through a geographic evaluation of survey data collected through recently completed research. Working with surveys in two of the cities surveyed in the United States, the authors analyze the attributes of individuals who increased and decreased their rail and bus usage in a geospatial context along with the population density of respondent home and work locations. The results inform the nuances of bikesharing impacts on the modal shift of urban residents with respect to public transportation."

The reality is that bus ridership is plummeting across the country. Who is doing it right? This article highlights the details of the ebb and flow of transit ridership in the US.

This University of Washington (UW) study focuses on a strategy to manage TNC driver stops when picking up and dropping off passengers with the aim of improving traffic flow in the South Lake Union (SLU) area. SLU is the site of the main campus for Amazon, the online retail company. The site is known to generate a large number of TNC trips, and Amazon reports high rates of ride-hailing use for employee commutes. This study also found that vehicle picking-up/dropping-off passengers make up a significant share of total vehicle activity in SLU. The center city neighborhood is characterized by multiple construction sites, slow speed limits (25 mph) and heavy vehicle and pedestrian traffic.

A plan to develop a data standard for technology that could monitor and manage various mobility services has raised privacy fears.

Traffic at the airports—even before you get inside—has gotten worse. The cause is not just the record number of travelers. It’s also the shift to ride sharing.

When ride-hailing services stormed into cities in the 2010s they offered a grand utopian promise: By tapping into America’s vast reservoir of idle vehicles, on-demand, app-based rides would reduce the need for personal car ownership and ultimately remove cars from the road. But now, less than a decade into this experiment, the industry is ‘fessing up. The ride-hailing giants released a joint analysis showing that their vehicles are responsible for significant portions of VMT in six major urban centers. Still, Uber and Lyft’s combined share is still vastly outstripped by personal vehicles.

Smartphone data from riders and drivers schlepping meals for restaurant-to-home courier service Deliveroo shows that bicycles are faster than cars. In towns and cities, bicyclists are also often faster than motorized two-wheelers.

In 2013, advocates, planners, and policymakers were abuzz with the 10.7 billion rides taken on transit, an all-time U.S. record. Yet the discussion focused too much on the sheer number of rides, without a deep look at the riders themselves, and particularly the changing attitudes that are propelling recent ridership increases. TransitCenter commissioned a survey to take that deeper look. We now have a snapshot into perceptions of transit and neighborhoods in 2014. As Millennials take center stage in American life and the Baby Boom generation confronts retirement, both the transit and real estate industries will have to adjust.

This report draws on results from six focus groups in New York, Raleigh and Denver as well as a survey of 3,000 people in 17 U.S. metropolitan areas with varying levels of transit development and ridership. It builds on the findings from TransitCenter’s first Who’s On Board report released in 2014.

With so much transportation funding going toward highways, it’s tempting to support any transit investment as a step in the right direction. But not all transit investments will produce service that helps people get where they need to go. To make transit a useful travel option that people want to ride, says TransitCenter, there are three basic goals that officials and advocates should strive for: speed, frequency and reliability, walkability and accessibility.

Public transit accounts for only 1% of U.S. passenger miles traveled but nevertheless attracts strong public support. Using a simple choice model, we predict that transit riders are likely to be individuals who commute along routes with the most severe roadway delays. These individuals’ choices thus have very high marginal impacts on congestion. We test this prediction with data from a sudden strike in 2003 by Los Angeles transit workers. Estimating a regression discontinuity design, we find that average highway delay increases 47% when transit service ceases. This effect is consistent with our model’s predictions and many times larger than earlier estimates, which have generally concluded that public transit provides minimal congestion relief. We find that the net benefits of transit systems appear to be much larger than previously believed.

Shared micromobility devices could thrive in a city like New York where individuals are encouraged to get out of their cars due to impending congestion pricing tolls and an expansion of protected bike lanes, according to the report. But biker and pedestrian safety remain a major issue in U.S. cities. Therefore, the most effective way to get people to use micromobility devices is to make them easy and safe to use, INRIX Transportation Analyst Trevor Reed told Smart Cities Dive in an email.

The Indiana Toll Road in the US has reduced traffic incidents by 30 per cent using Extreme Networks intelligent transportation system. The Indiana Toll Road Concession Company (ITRCC) deployed the software-driven network, which uses Extreme’s Smart OmniEdge technology to provide real-time updates on traffic patterns, enabling safer, more coordinated use of the roadway.

First came e-bikes, then scooters. Now the District is adding mopeds to the mix of micromobility services available in the nation’s capital. Looking forward, they are focused on luring electric tricycles (trikes) and e-cargo bikes to the city. D.C. transportation officials say they’re open to testing whatever happens to be the next big thing in transportation technology.

Seniors need transportation alternatives more than ever, but many are intimidated by ride-hailing apps." This article explores how transportation network companies are providing transportation options for seniors.

The purpose of this report is to provide information on TNC activity in San Francisco, in order to help the San Francisco County Transportation Authority (Transportation Authority) fulfill its role as the Congestion Management Agency for San Francisco County. The report is also intended to inform the Transportation Authority board which is comprised of the members of the San Francisco Board of Supervisors, as well as state and local policy-makers in other arenas, and the general public, on the size, location and time-of-day characteristics of the TNC market in San Francisco.

This report summarizes findings from a three-year collaboration between the World Economic Forum and The Boston Consulting Group (BCG) to explore how autonomous vehicles could reshape the future of urban mobility. The project built on the collective insights generated from the Autonomous and Urban Mobility Working Group (Working Group) of the System Initiative on Shaping the Future of Mobility, composed of roughly 35 business executives from diverse industries (including automotive, technology, logistics, insurance, utilities and infrastructure) that convened for 10 full-day workshops and numerous conference calls.

In the last ten years transit use in Southern California has fallen significantly. This report investigates that falling transit use. We define Southern California as the six counties that participate in the Southern California Association of Governments (SCAG) – Los Angeles, Orange, Riverside, San Bernardino, Ventura and Imperial. We examine patterns of transit service and patronage over time and across the region, and consider an array of explanations for falling transit use: declining transit service levels, eroding transit service quality, rising fares, falling fuel prices, the growth of Lyft and Uber, the migration of frequent transit users to outlying neighborhoods with less transit service, and rising vehicle ownership. While all of these factors probably play some role, we conclude that the most significant factor is increased motor vehicle access, particularly among low-income households that have traditionally supplied the region with its most frequent and reliable transit users.

This briefing document concisely conveys the key findings of NCHRP Research Report 845: Advancing Automated and Connected Vehicles: Policy and Planning Strategies for State and Local Transportation Agencies. NCHRP Research Report 845 assesses policy and planning strategies at the state, regional, and local levels that could influence private-sector automated vehicle (AV) and connected vehicle (CV) choices to positively affect societal goals. The researchers identified and described mismatches between potential societal impacts and factors that influence private-sector decisions on CV and AV technologies. Policy and planning actions that might better align these interests were then identified. Researchers and the project oversight panel identified the promising actions and then conducted in-depth evaluations of the feasibility, applicability, and impacts of 18 strategies.

The development of self-driving, or autonomous, vehicles is accelerating. Here’s how they could affect consumers and companies.

This article is about the development of microtransit. It suggests that microtransit can be the answer to underused, oversized public buses. And the technology such as routing software can improve the services as well.

This report by KPMG discusses how the new market will look like for autonomous future. It talks about transportation market, new customer demand, change of economic models, trip mission, and other market changes.

One of the more confusing words frequently associated with robocars (and all discussion of the future of transportation) is "shared." Unfortunately, this means two very different things, with quite different consequences.

Ford and other companies say the industry overestimated the arrival of autonomous vehicles, which still struggle to anticipate what other drivers and pedestrians will do.

To help decision-makers understand the impact of AV technology on regional plans, modeling tools should anticipate automated vehicles’ effect on transportation networks and traveler choices.This research uses the Seattle region’s activity based travel model to test a range of travel behavior impacts from AV technology development. The existing model was not originally designed with automated vehicles in mind, so some modifications to the model assumptions are described in areas of roadway capacity, user values of time, and parking costs. Larger structural model changes are not yet considered.

"While recent policies directed toward multimodal or complete streets have encouraged increased funding for bicycle- and pedestrian oriented projects, many streets are still plagued by unsafe conditions. This is especially true for one-way streets, which studies show often create unsafe crossing conditions. This study evaluates changes to street dynamics after a two-way street conversion in Louisville, Kentucky. We find that traffic flow increased after implementation of two-way flow, but traffic accidents decreased. We also note other ancillary benefits, such as increase in property values and reduced crime. These results provide evidence that conversions can promote mobility, safety, and livability."
