Shared Mobility

Mobility patterns in our cities are changing with the onset of shared mobility services. However, publicly available information on the use of shared mobility services is lagging behind. This study set out to fill this data gap by gathering web-based travel diary survey from carsharing and Transportation Network Company (TNC) users in the San Francisco Bay Area. Respondents were screened to be regular users of shared mobility services. The shared use reported in our sample was primarily car sharing and TNC, with bike sharing not being reported enough to be studied here. Our analysis drew...

Public agencies have subsidized taxi rides for people who have difficulty driving a car or using the regular transit system – targeting older residents and people with disabilities. There is interest among public agencies to add transportation network companies (TNCs), such as Uber and Lyft, to subsidized ride programs as a travel option due to the widespread availability of TNCs and high-quality service. Key issues include the need for wheelchair accessible vehicles, subsidy needs, and clients who lack or are uncomfortable using a smartphone and credit card. This research included a...

Most cars carry at least four passangers, but the average auto occupancy rate for all trips in the US is only 1.6 persons. Because all the empty seats in cars represent our greatest source of untapped transportation capacity, promoting ridesharing is of considerable interest. Government agencies across the country employ ridesharing programs both to provide transportation at low cost and to reduce traffic congestion and the other costs of solo driving. The rigidity of conventional ridesharing arrangements, which generally require fixed travel times, presents a barrier to many people. But...

This paper presents the findings of an “Integrated Hydrogen/Intelligent Transportation Systems Evaluation for the California Department of Transportation” project that was conducted by the University of California – Berkeley. The project reviewed state hydrogen activities suggested potential applications of combined hydrogen and intelligent transportation system (ITS) technologies that warrant further study and field-testing. The main concept underlying this study is the potential for synergies between two rapidly evolving areas of advanced transportation and energy technology: hydrogen...
