Shared Mobility

Automated Vehicles, On-Demand Mobility and Environmental Impacts

Greenblatt, Jeffery
Shaheen, Susan, PhD
2015

We review the history, current developments, projected future trends and environmental impacts of automated vehicles (AVs) and on-demand mobility, and explore potential synergies. Many automobile manufacturers and Google plan to release AVs between 2017 and 2020, with potential benefits including increased safety, more efficient road use, increased driver productivity and energy savings. Estimates of AV energy use and greenhouse gas (GHG) emissions range from an ~80 % or greater decrease to a threefold increase; however, we argue that net decreases are likely. On-demand mobility services...

2020

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, a MOD Sandbox Independent Evaluation was conducted that includes an analysis of project impacts from performance measures provided by the project partners and an assessment of the business models used. This document presents the Evaluation Report for the BART Integrated Carpool to Transit Access Program project. The project tested...

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.)...

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)

Shaheen, Susan, PhD

2019

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...

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...

Shared Mobility: Current Practices and Guiding Principles Brief

Shaheen, Susan

2016

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an as-needed basis. The term shared mobility includes various forms of carsharing, bikesharing, ridesharing (carpooling and vanpooling), and on-demand ride services. It can also include alternative transit services, such as paratransit, shuttles, and private transit services (called microtransit), which can supplement fixed-route bus and rail services. With diverse options for mobility on the rise, smartphone...
