Connectivity
On-demand ridesourcing services from transportation network companies (TNCs), such as Uber and Lyft, have reshaped urban travel and changed externality costs from vehicle emissions, congestion, crashes, and noise. To quantify these changes, we simulate replacing private vehicle travel with TNCs in six U.S. cities.
Microtransit—shared transportation that offers dynamic routing and scheduling to efficiently match demand—is emerging as an ally to fixed-route services. However, its positive impacts are too often constrained by the politics and economics imposed by existing transit infrastructure. This paper proposes a solution that ‘‘flips transit on its head.’’ By rapidly prototyping microtransit services across cities and analyzing supply-demand mismatches, it is possible to launch truly data-driven transit services. To illustrate the framework, a unique dataset generated from a year of Dallas Area Rapid Transit’s GoLink service, one of the largest ondemand microtransit services in North America, is used. Mapping and machine learning are combined to empower planners to ‘‘join the dots’’ when (re)designing fixed-route transit lines. It is shown that microtransit should not simply fill in the gaps left by inefficiently scheduled bus routes: by incorporating it fully into their planning processes, cities and transit agencies could dramatically reverse the fortunes of public transit.
Many cities are rolling out bike share programs. However, few studies have evaluated how bike share systems (BSS) are used to quantify their sustainability impacts. This study proposes a Bike Share Emission Reduction Estimation Model (BS-EREM) to quantify the environmental benefits from bike share trips and compare the greenhouse gas (GHG) emission reductions from BSS in eight cities in the United States, including New York, Chicago, Boston, Philadelphia, Washington D.C., Los Angeles, San Francisco, and Seattle. The BS-EREM model stochastically estimates the transportation modes substituted by bike share trips, considering factors such as trip distance, trip purpose, trip start time, the accessibility of public transits, and historical distributions of transportation mode choices.
Jarrett Walker, author of "Human Transit: How Clearer Thinking about Public Transit Can Enrich our Communities and Lives," writes about the costs and benefits of microtransit on his blog, "Human Transit". Walker is skeptical of Microtransit. He argues that it is spacially, economically, and fiscally inefficient and should only be used in very rare and specific cases.
The Handbook provides methods to quantify GHG emission reductions from a specified list of measures, primarily focused on project-level actions. The Handbook also includes a method to assess potential benefits of different climate vulnerability reduction measures, as well as measures that can be implemented to improve health and equity, again at the project level.
This study explores the full life cycle impacts of connected and automated vehicles beyond just operational impacts to understand net energy and environmental performance.
Rural Americans are less likely to own home broadband or a smartphone than suburban or urban Americans. This low percentage of adoption may be partly due to a lack of sufficient infrastructure to support high-speed internet.
In an effort to reduce personal vehicle usage and its carbon footprint Minneapolis has launched new “mobility hubs” where multiple modes of low- or no-carbon transportation are available in one convenient place.
This report examines several scenarios of connected and automated vehicle (CAV) adoption rates and studies their potential impacts on fuel efficiency and consumer costs. The results found massive uncertainties in potential long-term energy impacts from fully automated and highly connected vehicles in the high adoption rate scenario and similar uncertainties in the other scenarios. The authors outline the gaps in existing research and suggest routes for further research in order of importance.
This paper surveys emerging mobility services in order to highlight the key points of the concept of “mobility as a service” and to develop an index that evaluates the level of mobility integration of each service.
This article is a literature review of the definition and effects of urban sprawl for the purpose of implementing planning policies that discourage sprawl.
“This research aimed to look at the future of mobility and MaaS from a perspective of society, to look not only at the challenges to enabling a MaaS ecosystem but the potential direct and indirect effects on the wider transport system and city.”
“The purpose of this paper is to develop a topological approach to characterizing the MaaS concept in order to: 1) facilitate more meaningful discussions of the MaaS concept, 2) enable the ‘comparison of’ different services, 3) understand MaaS’ requirements and effects in terms of society, business, users/ customers, and technology, and 4) aid in the integration of societal goals.”
In New York City, conflict has erupted between private ride-hailing services and neutral third-party mobility platforms battling for bikeshare access. Companies like Lyft and Mobility as a Service (MaaS) providers such as Transit both want to remove the friction of switching in between modes for commuters, however the ride-sharing companies want to build brand loyalty while third-party MaaS platforms want to offer access to all mobility options available.
Sustainable, inclusive, prosperous, and resilient cities depend on transportation that facilitates the safe, efficient, and pollution-free flow of people and goods, while also providing affordable, healthy, and integrated mobility for all people. The pace of technology-driven innovation from the private sector in shared transportation services, vehicles, and networks is rapid, accelerating, and filled with opportunity. At the same time, city streets are a finite and scarce resource.These principles, produced by a working group of international NGOs, are designed to guide urban decision-makers and stakeholders toward the best outcomes for all.

This report combines recently published research and newly available data from a national travel survey and other sources to create the first detailed profile of TNC ridership, users and usage. The report then discusses how TNC and microtransit services can benefit urban transportation, how policy makers can respond to traffic and transit impacts, and the implications of current experience for planning and implementation of shared autonomous vehicles in major American cities.
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.
This paper introduces Metrolinx’s recently released Mobility Hub Guidelines and highlights two key aspects of the document: the importance of classifying the current and planned urban context and transportation function at a mobility hub, and methods to overcome challenges in achieving both transport and placemaking roles.

Connected and fully automated or autonomous vehicles (CAVs) are becoming increasingly viable 23 as a technology and may soon dominate the automotive industry. Once CAVs are sufficiently 24 reliable and affordable, they will gain greater market penetration, generating significant economic 25 ripple effects throughout many industries. This paper synthesizes and expands upon analysis from 26 multiple reports on the economic effects of CAVs across 13 different industries and the overall 27 economy.
"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."
"Beyond Mobility is about prioritizing the needs and aspirations of people and the creation of great places. This is as important, if not more important, than expediting movement. A stronger focus on accessibility and place creates better communities, environments, and economies. Rethinking how projects are planned and designed in cities and suburbs needs to occur at multiple geographic scales, from micro-designs (such as parklets), corridors (such as road-diets), and city-regions (such as an urban growth boundary). It can involve both software (a shift in policy) and hardware (a physical transformation). Moving beyond mobility must also be socially inclusive, a significant challenge in light of the price increases that typically result from creating higher quality urban spaces."
In 2012 UN-Habitat presented to the world the notion of city prosperity, which implies success, wealth, thriving conditions, and wellbeing, as well as opportunity for all. Cities that foster infrastructure development, environmental sustainability, high productivity, quality of life, and equity and social inclusions are considered prosperous cities, Building on the notion of prosperity, UN-Habitat emphasizes that for a city to be prosperous, it must have a generous and well-designed street pattern. In this report, UN-Habitat advocates for a holistic approach to streets as public spaces that embraces the concept of livability and completeness. A good street pattern boosts infrastructure development, enhances environmental sustainability, supports higher productivity, enriches quality of life, and promotes equity and social inclusion.
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 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."
"This report addresses the need for knowledge by providing practical considerations of essential pilot program elements. To assist transit agencies, this report illustrates previously executed autonomous shuttle pilot programs, identifies the core elements of a pilot program, and discusses the relationship between elements. To accomplish these tasks, this report reviews nine European autonomous shuttle pilot programs, literature surrounding the topic, and interviews key personnel associated with the pilot programs. The results of this research help transit agencies make informed decisions about approaching autonomous shuttle pilot programs in public transportation."
"In this chapter I address three commonly misunderstood aspects of vehicle automation: capability, deployment, and connectivity. For each, I identify a myth pervading public discussion, provide a contradictory view common among experts, explain why that expert view is itself incomplete, and finally discuss the legal implications of this nuance. Although there are many more aspects that merit clarification, these three are linked because they suggest a shift in transportation from a product model to a service model, a point with which I conclude."
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.
