Intelligent transportation systems (ITS) have primarily focused on systems management. To further improve connectivity and safety in the future, ITS might embrace a more holistic planning approach. While the future of ITS remains an open question, its evolution is closely linked to how the world evolves on many dimensions, social, political, economic, legal, and environmental. In this paper, the authors present results from four expert workshops. These consisted of an initial steering committee workshop (February 2011), two expert scenario-planning workshops (June 2011), and a final...

In recent years, technological and social forces have pushed smartphone applications (apps) from the fringe to the mainstream. Understanding the role of transportation apps in urban mobility is important for policy development and transportation planners. This study evaluates the role and impact of multimodal aggregators from a variety of perspectives, including a literature review; a review of the most innovative, disruptive, and highest-rated transportation apps; interviews with experts in the industry, and a user survey of former multimodal aggregator RideScout users. Between February...

Planning for Shared Mobility

Cohen, Adam

2018

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...

Cycling for transportation has become an increasingly important component of strategies to address public health, climate change, and air quality concerns in urban centers. Within this context, planners and policy makers would benefit from an improved understanding of available interventions and their relative effectiveness for cycling promotion. We examined predictors of bicycle commuting that are relevant to planning and policy intervention, particularly those amenable to short- and medium-term action. We estimated a travel mode choice model using data from a...

Pooling Passengers and Services

2018

In the past ten years, passenger and goods movement transportation systems have evolved rapidly. Shared mobility providers are filling gaps in service and creating new markets for delivery; vehicle fleets continue to electrify; and pooled services are increasing vehicle occupancy. The uptake of innovative pooled services, as well as automation, promise to continue the trend of transformative change. As the private sector continues to advance, there is a great need for institutional flexibility in managing and coordinating all users of transportation infrastructure, particularly on the...

Estudiamos la experiencia de cinco casos en tres ciudades colombianas (Bogotá, Pereira, y Barranquilla) en la implementación desarrollo urbano orientado a buses rápidos. Aunque los casos reflejan un éxito desigual, algunas lecciones se desprenden del análisis. Primero es el papel activo de las autoridades municipales a cargo de la planificación es clave. Segundo, es la complejidad institucional durante el proceso de planificación para la coordinación entre las inversiones en transporte y el desarrollo del suelo, lo cual incide en el éxito del proyecto. Tercero, es la tendencia del...

California Transportation Plan 2050: Northern and Southern California Visioning Sessions Findings

Improving California’s transportation system requires cross-sector collaboration, particularly as technologies, policies, and regulations develop simultaneously. The California Transportation Plan (CTP) 2050 aims to integrate perspectives from a diverse array of stakeholder that may not typically participate in the statewide planning process. The Visioning Sessions were conducted in two day-long visioning workshops in October 2018 in Southern and Northern California. Overall, these visioning sessions initiated a much-needed dialogue among experts and practitioners from diverse backgrounds...

Social Equity Impacts of Congestion Management Strategies

2019

This white paper examines the social equity impacts of various congestion management strategies. The paper includes a comprehensive list of 30 congestion management strategies and a discussion of equity implications related to each strategy. The authors analyze existing literature and incorporate findings from 12 expert interviews from academic, non-governmental organization (NGO), public, and private sector respondents to strengthen results and fill gaps in understanding. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework (...

David Godschalk: A Planner’s Lifelong Search for the Sweet Spot

2019

David R. Godschalk, professor emeritus in the Department of City and Regional Planning at the University of North Carolina, Chapel Hill, passed away in early 2018. In this essay we reflect on Dave’s planning scholarship and practice. We discuss his main contributions in 4 prominent areas. First is the importance of public participation and collaboration for the planning and governance of communities. He argued for democratizing and recasting public participation, with planners working alongside community members coproducing plans and incorporating uncertainty, new information, and...

Social (In) Equity in Access to Cycling Infrastructure: Examining the Distribution of Bike Lanes with Respect to Area-Level Sociodemographic Characteristics in 23 Large US Cities

Cycling advocates have recently argued that low-income and minority communities across the U.S. have disproportionately low access to bike lanes. To date, however, quantitative evidence of disparities in access to bike lanes has been limited to a small number of cities. We addressed this research gap by examining cross-sectional associations between bike lanes and sociodemographic characteristics at the block group level for 22 large U.S. cities (n = 21,843 block groups). Dependent variables included the presence (yes/no), coverage, connectivity, and proximity...
