Right-of-way

Many studies have noted that denser and more accessible environments with higher level-of-service (LOS) tend to encourage higher levels of walking and bicycling activity. As streets are increasingly designed to facilitate safe cycling through built environment interventions, little has been done to evaluate perceptions of safety on different typologies, particularly one vs. two-way corridors. Theory would suggest that many individuals frame their commutes based in-part on the perceived safety of the environment, yet little research looks at varying street design and this perception. This study uses a moving camera approach to evaluate the perceived cycling comfort for drivers and cyclists on different roadway designs (multi-lane, one way; two-way, bidirectional street; single-lane, one-way).

With the rapid growth of ride-hailing services, e-commerce and on-demand deliveries, demand for curb space has increased in urban areas.

This report studies how the use of Transportation Network Companies are increasing the demand for curb space and the potential related issues such as access, circulation, and safety.

This article details a study done in the neighborhood of Rosslyn in Arlington, Virginia to understand the relationship between e-scooter riders and non-riders in terms of e-scooter parking and pedestrian safety.

"The City of Santa Monica designed a pilot program to test shared electric scooters and bikes operated by private companies, using a flexible approach that could be responsive to community needs, technological advancements, and a nascent and evolving industry."

"NACTO research in seven cities shows that pairing bike share with protected bike lanes encourages riding, increases the visibility of people on bikes, and reduces overall biking risk."

Uber is working on a plan to launch an urban air taxi service and has just joined with California-based aerospace company Joby Aviation.

Despite a growing economy, there has been a decrease in the average miles driven due in part to alternate modes of transportation and more opportunities to work and shop remotely.

Cities around the world are beginning to prioritize people over vehicles by closing major streets to traffic and opening them up to pedestrians, cyclists, public transit.

The NUMO New Mobility Atlas is an extensive, data-driven platform mapping the rapid proliferation of new mobility, including micromobility, in cities around the world. Developed in partnership with partner organizations from the public and private sectors, the Atlas uses open data to track which shared transportation options — currently dockless scooters, bicycles and mopeds — are available in cities.

This is a fact sheet suitable for use as a printed handout on Urbanism Next's topline research findings regarding TNCs.

The purpose of this report is to analyze potential impacts and offer recommendations for the cities of Gresham and Eugene, OR, to understand the potential impacts of new mobility technologies – with an emphasis on autonomous vehicles (AVs) – and prepare a policy and programmatic response. While Gresham and Eugene are case studies, it provides mid-sized communities information on how new mobility services could impact their communities and what they can do about it, from broad strategies to specific policy responses. While this work focuses on the various new mobility and goods delivery services that currently exist, the framework that is discussed here is also applicable to emerging technologies that haven’t yet been introduced, such as autonomous vehicles (AVs).

Autonomous vehicles (AVs) are a near future reality and the implications of AVs on city development and urban form, while potentially widespread and dramatic, are not well understood. This report describes the first order impacts, or the broad ways that the form and function of cities are already being impacted by forces of change including⁠—but not limited to⁠—AVs and related technologies.

A blueprint for designing 21st century streets, the Guide unveils the toolbox and the tactics cities use to make streets safer, more livable, and more economically vibrant.

This is an exercise that deconstructs an urban and a suburban streetscape using the Restreet.com participatory design tool. Restreet was created by William Riggs, Mike Boswell and Ryder Ross in 2016 as a code fork from the Code for America project Streetmix. The idea was to democratize the way we plan streets and synthesize that data for policy and decision-making. The streets depicted show right-of-way needs eroding due to the prevalence of autonomous vehicles creating efficiency or the policy decision to do so in advance of their adoption. The final two slides show the submissions from the over 6,000 users since September and the related summary statistics. All suggest that policy that supports traffic calming and lane reductions to support multimodal transportation might be appropriate in the immediate future.

This policy paper focuses on the primary concept of the street as space that can be repurposed – real estate that can be allocated in similar or different ways than done currently. Cities generally refer to this publicly owned and regulated space from one side of the street to the other as the right of way (ROW). Our focus is on the centrality of the ROW in dictating many other community functions and values – transportation and otherwise. And our particular bias is to focus on the opportunities that AV technology is likely to create to rethink how the ROW is allocated, so that our communities can meet their substantial and unique environmental, social, and economic challenges.

This article describes the changing driving landscape in New York City. The city is making efforts to return the streets to the people and also optimize public transportation options. The pushback is steep again the community where the traffic is being pushed as well as with the business owners.

After 17 cyclists die after being hit on the roads in the first half of the year, the city decides to take major steps to improve bicycle safety.

"Mobility Plan 2035 (Plan) provides the policy foundation for achieving a transportation system that balances the needs of all road users. As an update to the City’s General Plan Transportation Element (last adopted in 1999), Mobility Plan 2035 incorporates “complete streets” principles and lays the policy foundation for how future generations of Angelenos interact with their streets."

The presentation given to the city council goes over the potential the future of the City of Vancouver has to offer and what the next steps may be.

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?

"This paper explores the relationships between transportation, land use and taxation. It investigates how current land tax and regulatory practices affect the amount of land devoted to roads and parking facilities, and how this affects transport patterns. It discusses ways to measure the amount of land devoted to transport facilities, examine how this varies under different circumstances, estimate the value of this resource, evaluate how tax policies and regulations policies treat this land, and analyze whether current practices are optimal in terms of various economic and social objectives."

The main objective of this research project is to provide FDOT with information and guidance on how best to begin to prepare for a future in which AV technology first takes root and then takes over the market. The FSU Research Team is investigating the potential impacts of widespread adoption of AV technology on the transportation network and urban form for four key land use and transportation nodes that are vital to the welfare of the State of Florida: Downtown, Office/Medical/University Center, Urban Arterial, and Transit Neighborhood. To accomplish this, the FSU Research Team engaged one-hundred planners, engineers, industry professionals, and public officials in a facilitated visioning session at the 2015 Florida Automated Vehicle Summit (FAV Summit). During this session the research team gathered input on how AVs will impact our communities and how the built environment will need to adapt to accommodate AVs in the coming decades.

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 provides a review of scenarios on these issues to date. Although some scenario studies provide useful insights about urban growth and change, very few consider detailed impacts of AVs on urban form, such as the density and mix of functions, the layout of urban development and the accessibility of locations, including the distance to transit."

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.

This edition of the Blueprint is organized into three parts, taking the reader through the principles and political structures that underscore and shape our vision of the future, key policy choices around transit, pricing, freight, and data that can reshape our cities, and finally, exploring the sweeping vision for city streets of the future: Shaping the Autonomous Future Today, Policies to Shape the Autonomous Age, and Design for the Autonomous Age

Urban Mobility in a Digital Age is a transportation technology strategy designed to build on the success and innovation of the City of Los Angeles and its Department of Transportation (LADOT) as regulator and transportation service provider in a complex and evolving ecosystem of public and private services.

The purpose of this document is to identify and outline the policies, programs and strategies being adopted by the City of Portland (City), as part of a regionally coordinated effort to promote and integrate electric vehicles (EVs) into our transportation system and to capitalize on local economic development opportunities from this emerging industry.

"Dockless bike share systems present an opportunity for cities to expand access to bike share by lowering costs and geographic barriers, but also create additional challenges in the areas of maintenance, parking, and right-of- way management. Most dockless providers are also private, venture-capital funded entities, representing a significant departure from current public and non-profit approaches. Other cities have encountered challenges in securing cooperation from these operators in areas such as data transparency. This raises a key question: To what extent can cities use contracts and governance to exchange use of the public right-of-way for operating requirements that advance equity, accessibility, innovation, and other goals? Using case studies from other U.S. cities and drawing insights from the wider “smart mobility” literature, this research presents recommendations for regulating dockless bike share in cities and ties these approaches to the implementation of Nice Ride Minnesota’s dockless pilot. "

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.

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.

"To better understand the emerging area of low-speed automated shuttles, the U.S. Department of Transportation (USDOT) Intelligent Transportation Systems Joint Program Office (ITS JPO) partnered with the John A. Volpe National Transportation Systems Center (Volpe) to review the current state of the practice of low-speed automated shuttles. These vehicles share many characteristics with other forms of automated vehicles but include unique considerations in terms of design, operations, and service type, including: fully automated driving (intended for use without a driver); operational design domain (ODD) (restricted to protected and less-complicated environments); low speeds (cruising speeds around 10-15 mph); shared service (typically designed to carry multiple passengers, including unrestrained passengers and standees); and shared right-of-way with other road users, either at designated crossing locations or along the right-of-way itself. This report defines design and service characteristics; discusses the deployers, their motivations, and their partners; and provides information on demonstrations and deployments, both international and domestic. The document also provides context on common challenges and suggested mitigations. Building on all of this information, the document identifies several research questions on topics ranging from safety and accessibility to user acceptance and societal impacts."

"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."

This paper presents ten key challenge areas that need to be at the center of automated vehicle discussions across all sectors and stakeholders, along with a glossary of key terms. It is intended to serve as a discussion guide and orientation piece for people entering the conversation from a wide variety of perspectives, including advocacy, public policy, research, injury prevention, and technology developers.

This document provides guidance for cities and public entities as they look to manage and regulate Shared Active Transportation Companies that are not otherwise managed through competitive procurement processes or contracts. It focuses on clearer and more formal management of public-use mobility options that are not created under the auspices of a public entity. The regulatory focus of this document is not based on the technology or the business plan. Rather, as businesses operating on city streets, Shared Active Transportation Companies need to be overseen and regulated by public entities when they are not otherwise managed through existing processes.

Depending on how you look view transportation, bikes and scooters are the key to future, clean urban mobility or a sideshow that distracts from maintaining mobility across large metropolis. But the basic problem – the reason we’re having a hyper-emotional discussion about these transportation modes on both sides – is that we’re not framing the issue right.

"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."

In recent years, economic, environmental, and social forces have quickly given rise to the “sharing economy,” a collective of entrepreneurs and consumers leveraging technology to share resources, save money, and generate capital. Homesharing services, such as Airbnb, and peer-to-peer carsharing services, such as Getaround, have become part of a sociodemographic trend that has pushed the sharing economy from the fringe and more to the mainstream. The role of shared mobility in the broader landscape of urban mobility has become a frequent topic of discussion. Major shared transportation modes—such as bikesharing, carsharing, ridesourcing, and alternative transit services—are changing how people travel and are having a transformative effect on mobility and local planning.

This report analyzes traffic impacts from the 2015 implementation of a pilot “road diet” on Lincoln Avenue, in the City of San Jose, California, comparing data on traffic volumes and speeds from before and after the road diet was implemented. The analysis looks at impacts on both the road diet location itself and on surrounding streets likely to have been impacted by traffic diverted off the road diet segment. The results within the road diet zone were as expected, with falling volumes and numbers of speeders. The all-day data aggregated by street type (e.g., neighborhood streets, major streets) showed limited overall negative impacts outside the road diet segment. These summary results do not tell the entire story, however. Individual locations, particularly among the neighborhood streets, saw more noticeable negative impacts. The report ends with recommendations for best practices in designing and conducting road diet evaluation studies.
