GIG Car Share is a free-floating carsharing system that began operations in the East Bay in April 2017. Similar to other free-floating carsharing systems, such as car2go and ReachNow (which later combined as ShareNow), members of GIG have access to a fleet of vehicles which they can book and unlock via an app. Once booking the vehicle, members can drive anywhere, but must park back in the home zone in order to terminate their session. The price of driving a GIG vehicle is charged per hour, per mile, or per day, and is calculated based on the lowest cost to the user. This report uses the...

Intelligent Transportation Systems

2013

Intelligent transportation systems (ITS) represent a group of technologies that can improve transportation system management and public transit, as well as individual decisions surrounding many aspects of travel. ITS technologies include state-of-the art wireless, electronic, and automated technologies with a goal to improve surface transportation safety, efficiency, and convenience. Reducing energy consumption, while not a primary goal for ITS, is a demonstrated ITS benefit in certain circumstances. This paper reviews and summarizes key energy benefits associated with a variety of ITS...

This report provides Mobility on Demand (MOD) planning and implementation practices and tools to support communities. The report discusses different stakeholders in the MOD ecosystem and the role of partnerships in filling spatial, temporal, and other service gaps. Additionally, the report discusses how MOD can be integrated into transportation planning and modeling. The report also discusses shared mobility implementation considerations, such as rights-of-way management, multimodal integration, data sharing, equity, labor impacts, and the role of pilot evaluations. Finally, the report...

Mobility on Demand: State of the Industry Practitioner Census, Fall 2021

2021

The Transportation Sustainability Research Center (TSRC) at the University of California, Berkeley is pleased to present the results of the Mobility on Demand (MOD) State of the Industry Practitioner Census. The global pandemic has led to a challenging period for the transportation sector. Nevertheless, the industry has shown resilience and innovation. This industry outlook provides information on MOD and Mobility as a Service (MaaS) developments throughout the United States (U.S.) and highlights some industry changes in response to the pandemic.

Mobility on Demand (MOD) Sandbox Demonstration: Vermont Agency of Transportation (VTrans) OpenTripPlanner

Martin, Elliot
Nichols, Aqshems
Cohen, Adam

2021

This report documents the results of an independent evaluation of the Vermont Agency of Transportation’s (VTrans) OpenTripPlanner (OTP), called Go! Vermont, part of the Federal Transit Administration (FTA) Mobility on Demand (MOD) Sandbox Demonstration program. The project intended to serve as an alternative to other trip planners by including flexible transit options such as route deviation, dial-a-ride, and other demand-responsive alternatives and to analyze web traffic data to determine the level of user activity attracted by Go! Vermont since its launch. The evaluation compared the...

Strategies to Overcome Transportation Barriers for Rent Burdened Oakland Residents

Pan, Alexandra
Shaheen, Susan, PhD
2021

Shared mobility is gaining traction in the transportation community as a potentially more environmentally friendly alternative to automobile travel and complement to public transit. However, adoption and use of shared mobility by low-income individuals lags behind other demographic groups. Additional research is needed to better understand the transportation needs of low-income travelers and how public agencies, community-based organizations, and shared mobility operators can work together to best serve those needs. This research fills gaps in understanding the potential policy strategies...

Creative Reallocation of Curbs, Streets, Sidewalks Accelerated by the Pandemic May be Here to Stay

Shaheen, Susan, PhD
Cohen, Adam
Broader, Jacquelyn
2023

Curb space has been traditionally designed for private vehicle parking, public transit, and passenger and commercial loading. However, in recent years, a growing number of newservices and activities have increased the demand for limited curb space, including passenger pick-up and drop-off; last-mile delivery (e.g., courier network services, personal delivery devices); electric vehicle (EV) charging; micromobility parking and use (e.g., personally owned and shared bikes and scooters); and carsharing services. The curb serves a variety of functions such as vehicle and device storage (...

An Assessment of the Potential Weather Barriers of Urban Air Mobility (UAM)

Reiche, Colleen PhD
Brody, Frank
McGillen, Christian
Siegel, Joel
Cohen, Adam
2018

Urban Air Mobility (UAM) is an emerging concept of air transportation where small package delivery drones to passenger-carrying air taxis operate over populated areas from small towns to the largest cities. This could revolutionize the way people move within and around cities by shortening commute times, bypassing ground congestion, and enabling point-to-point flights across cities. In recent years, several companies have designed and tested enabling elements of this concept, including; prototypes of Vertical Take-Off Landing (VTOL) capable vehicles, understanding of operational concepts,...

Generic Time- and Method-Interdependencies of Empirical Impact-Measurements: A Generalizable Model of Adaptation-Processes of Carsharing-Users' Mobility-Behavior Over Time

Firnkorn, Jörg
Shaheen, Susan, PhD
2016

The purpose of this article is to advance empirical sustainability-evaluations of carsharing-systems. Carsharing, a frequently cited example of a product–service system (PSS), is currently morphing from a niche into a mainstream mode of transportation. Carsharing has the potential to provide a more sustainable mobility-option compared to private car usage, for example by reducing the overall motor-vehicle traffic in cities. However, the quantification of this potential is complex, and few studies have analyzed the fundamental impacts of the chosen measurement-methodology on the results of...

Struggling to Connect: Housing and Transportation Challenges of Low-Income Suburban Residents in the San Francisco Bay Area

Pan, Alexandra
Deakin, Elizabeth, PhD
Shaheen, Susan, PhD
2024

Suburban areas have lower density development than urban areas, which may make them less accessible for the growing population of low- and moderate-income suburban residents, particularly those without a personal vehicle. This research examines factors that lead these households to move to suburban areas and identifies accessibility barriers they face. We use a mixed-methods approach with Public Use Microdata Sample (PUMS) data from the U.S. Census, online/in-person surveys (n=208), and interviews conducted in English and Spanish (n=25) with households in Contra Costa County with an income...
