Public Bikesharing in North America: Early Operator Understanding and Emerging Trends

Shaheen, Susan, PhD
Cohen, Adam
Martin, Elliot, PhD
2013

Public bikesharing—the shared use of a bicycle fleet by the public—is an innovative mobility strategy that has recently emerged in major North American cities. Bikesharing systems typically position bicycles throughout an urban environment, among a network of docking stations, for immediate access. Approximately five years ago, information technology (or IT)-based bikesharing services began to emerge in North America. Between 2007 and March 2013, 28 IT-based programs have been deployed–24 are operational, two are temporarily suspended, and two are now defunct in the United States (U.S.)...

2022

The State of California is currently moving forward with a road usage charge (RUC) demonstration program, creating promising research opportunities to examine the potential social equity implications of a shift from a gas tax to a RUC system in California. RUC . To this aim, this study investigates the relative burden of gas taxes and mileage-based RUC across various sociodemographic and geographic dimensions by examining key trends in road use, vehicle ownership, fuel consumption, use of RUC-related technologies, and attitudes/opinions related to RUC adoption. Expert interviews were...

The Mobility on Demand (MOD) Sandbox Demonstration Program provides a venue through which integrated MOD concepts and solutions – supported through local partnerships – are demonstrated in real-world settings. For each of the 11 MOD Sandbox Demonstration projects, the MOD Sandbox Independent Evaluation includes an analysis of project impacts from performance measures provided by the project partners, as well as an assessment of the business models used. This report constitutes the Evaluation Plan for the TriMet OTP SUM Sandbox project. It includes the following chapters: project overview;...

Tercer Informe Anual del Estado de al Industria de La Micromovilidad Compartida

La Asociación Norteamericana de Bicicletas y Monopatines Compartidos (North American Bikeshare & Scootershare Association – NABSA)
2021

La Asociación Norteamericana de Bicicletas y Monopatines Compartidos (North American Bikeshare & Scootershare Association – NABSA) se complace en presentar nuestro tercer informe anual sobre el estado del sector de la micromovilidad compartida. En 2021, el sector continuó respondiendo a la pandemia del COVID-19, y la micromovilidad compartida cubrió vacíos críticos en la movilidad esencial. El sector siguió recuperándose y demostrando una enorme resiliencia, con un número de sistemas que supera los niveles anteriores a la pandemia. Este informe hace unseguimiento de este progreso y...

Ridesharing (Carpooling and Vanpooling)

Ridesharing allows travelers to share a ride to a common destination and can include several forms (Shaheen & Cohen, 2019; Chan & Shaheen, 2011; SAE International, 2018). Ridesharing differs from for-hire vehicle services (i.e., transportation network companies (TNCs), ridesourcing, and ridehailing) in its financial motivation. When a ridesharing payment is collected, it partially covers the driver’s cost and is not intended to result in financial gain. Additionally, the driver has a common origin and/or destination with the passengers. In this toolkit, readers will find a summary...

The Low Carbon Fuel Standard (LCFS) can play a major role in reducing greenhouse gas emissions and stimulating improvements in transportation fuel technologies so that California can meet its climate policy goals. In Part 1 of this study we evaluated the technical feasibility of achieving a 10 percent reduction in the carbon intensity (measured in gCO2e/MJ) of transportation fuels in California by 2020. We identified six scenarios based on a variety of different technologies that could meet or exceed this goal, and concluded that the goal was ambitious but attainable. In Part 2, we examine...

How Public Education on Ecodriving Can Reduce Both Fuel Use and Greenhouse Gas Emissions

Martin, Elliot W.
Chan, Nelson D.
Shaheen, Susan A.
2012

Ecodriving, the concept of changing driving behavior and vehicle maintenance to impact fuel consumption and greenhouse gas (GHG) emissions in existing vehicles, has gained recent prominence in North America. One ecodriving strategy involves public education through Internet-based information dissemination. This paper presents the results of a controlled stated-response study conducted from June to December 2010 with approximately 100 University of California, Berkeley faculty, staff, and students, assessing the effectiveness of static ecodriving web-based information. A comparison of the...

Shared Mobility Policy and Modeling Workshop

Shaheen, Susan, PhD
Cohen, Adam
Farrar, Emily
2019

The market for personal mobility is changing rapidly due to shifting social and cultural trends, as well as technological advances, such as smartphones, information processing, widespread data connectivity, sharing, and vehicle automation. Shared, on-demand mobility represents a sustainable vision for future mobility with a reliable network of multimodal options that are available to all travelers. On March 22, 2019, the Local Government Commission (LGC) and the Transportation Sustainability Research Center (TSRC) at the University of California, Berkeley hosted the Caltrans Shared...

Current State of the Sharing Economy and Evacuations: Lessons from California

Wong, Stephen
Shaheen, Susan, PhD
2019

In many evacuations including wildfire evacuations, public agencies often do not have enough resources to evacuate and shelter all citizens. Consequently, we propose that the sharing economy, through private companies and/or private citizens, could be leveraged in disasters for transportation and sheltering resources. To assess this feasibility, we distributed surveys to individuals impacted by three major wildfires in California: 1) the 2017 October Northern California Wildfires (n=79), 2) the 2017 December Southern California Wildfires (n=226), and 3) the 2018 Carr Wildfire (n=284)....

Future of Public Transit and Shared Mobility: Scenario Planning for COVID-19 Recovery

Shaheen, Susan, PhD
Wong, Stephen, PhD
2021

In 2020, the novel coronavirus (COVID-19) pandemic enveloped the world, leading to a public health crisis that profoundly changed all aspects of society, especially multiple sectors in transportation such as public transit and shared mobility. With so much uncertainty about the future of travel, the transportation sector needs to move rapidly to shape the nature of public transit and shared mobility services during the COVID-19 recovery period. Consequently, the University of California Institute of Transportation Studies (UC ITS) and the Transportation Research Board’s (TRB) Executive...
