Carsharing and Partnership Management: An International Perspective

Shaheen, Susan
Sperling, Dan
Wagner, Conrad
2004

Most cars carry one person and are used for less than 1 hour per day. A more economically rational approach would be to use vehicles more intensively. Carsharing, in which a group of people pays a subscription plus a per-use fee, is one means of doing so. Carsharing may be organized through affinity groups, large employers, transit operators, neighborhood groups, or large carsharing businesses. Relative to car ownership, carsharing has the disadvantage of less convenient vehicle access but the advantages of a large range of vehicles, fewer ownership responsibilities, and less cost (if...

Review of California Wildfire Evacuations from 2017 to 2019

Wong, Stephen D.

2020

Between 2017 and 2019, California experienced a series of devastating wildfires that together led over one million people to be ordered to evacuate. Due to the speed of many of these wildfires, residents across California found themselves in challenging evacuation situations, often at night and with little time to escape. These evacuations placed considerable stress on public resources and infrastructure for both transportation and sheltering. In the face of these clear challenges, transportation and emergency management agencies across California have widely varying levels of preparedness...

Evolution of E-Mobility in Carsharing Business Models

Shaheen, Susan, PhD
Chan, Nelson
2014

Carsharing continues to grow worldwide as a powerful strategy to provide an alternative to solo driving. The viability of electric vehicles, or EVs, has been exam-ined in various carsharing business models. Moreover, new technologies have given rise to electromobility, or e-mobility, systems. This paper discusses the evolution of e-mobility in carsharing business models and the challenges and opportunities that EVs present to carsharing operators around the world. Operators are now anticipating in-creased EV proliferation into vehicle fleets over the next 5-10 years as technology,...

An Evaluation of Via Rideshare Service in West Sacramento: An Exploratory Analysis Through Surveys and Expert Interviews

Martin, Elliot, PhD

Shaheen, Susan, PhD
2019

The UC Berkeley Transportation Sustainability Research Center (TSRC) conducted an evaluation for the City of West Sacramento of the pilot Via Rideshare System, which began providing rides to customers in May of 2018 and is currently in operation. This analysis presents the findings from surveys and expert interviews. Surveys were deployed to both users and non-users of the pilot service in order to assess the behavioral impacts of the system on users and to evaluate non-user response to the system and why they had not yet opted to not use the service. The user survey, which collected 224...

Carsharing is a service in which individuals gain the benefits of private vehicle use without the costs and responsibilities of ownership. Individuals typically access vehicles by joining an organization that maintains a fleet of cars and light trucks. Fleets are usually deployed within neighborhoods and at public transit stations, employment centers, and colleges and universities. Typically, the carsharing operator provides gasoline, parking, and maintenance. Generally, participants pay a fee each time they use a vehicle (Shaheen, Cohen, Zohdy, 2016). Carsharing includes three types of...

Roundtrip Carsharing in New York City: An Evaluation of a Pilot Program and System Impacts

Martin, Elliot, PhD
Stocker, Adam
Nichols, Aqshems
Shaheen, Susan, PhD
2021

The study found that roundtrip carsharing in NYC mostly serves as a substitute for car rental, other personal vehicle modes, and personal vehicle ownership. The analysis showed that the broader pilot program had a modest impact on user behavior through carsharing (i.e., reduced vehicle ownership, reduced VMT, and mode shift). It also found that the pilot program likely expanded the membership base of carsharing to demographic cohorts that are traditionally underrepresented in carsharing populations (i.e., increased participation by lower education levels, lower household incomes, minority...

Bridging the Income and Digital Divide with Shared Automated Electric Vehicles

Lazarus, Jessica
Bauer, Gordon, PhD
Greenblatt, Jeffery, PhD
Shaheen, Susan, PhD
2021

This research investigates strategies to improve the mobility of low-income travelers by incentivizing the use of electric SAVs (SAEVs) and public transit. We employ two agent-based simulation engines, an activity-based travel demand model of the San Francisco Bay Area, and vehicle movement data from the San Francisco Bay Area and the Los Angeles Basin to model emergent travel behavior of commute trips in response to subsidies for TNCs and public transit. Sensitivity analysis was conducted to assess the impacts of different subsidy scenarios on mode choices, TNC pooling and match rates,...

Mobility on Demand (MOD) Sandbox Demonstrations Independent Evaluation (IE)-City of Palo Alto and Prospect Silicon Valley Bay Area Fair Value Commuting (FVC) Demonstration Project Evaluation Plan

2018

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 City of Palo Alto and Prospect Silicon Valley Bay Area Fair Value Commuting (FVC)...

Integrating Vehicle Design and Human Factors: Minimizing Elderly Driving Constraints

Shaheen, Susan
Niemeier, Debbie
2001

With a projected rise in the number of elderly, most of whom have also relied primarily on the private automobile for their mobility, it is likely that future adaptations in vehicle design will be linked in some part to the physical infirmities often faced by the elderly. This paper offers a bridge between medical research on the physical impairments of the elderly and automobile design and driving safety. We describe recent findings on the driving-related physical and cognitive impairments faced by the elderly. We then propose two major types of vehicle design and infrastructure...

Peer-To-Peer (P2P) Carsharing: Exploring Public Perception and Market Characteristics in the San Francisco Bay Area

Ballús-Armet, Ingrid
Shaheen, Susan, PhD
Clonts, Kelly

2014

Peer-to-peer (P2P) carsharing is an innovative approach to vehicle sharing in which vehicle owners temporarily rent their personal automobiles to others in their surrounding area. P2P carsharing belongs to the larger sharing economy, an economic model premised on the notion of collaborative consumption as opposed to ownership. This study examines current public perception of P2P carsharing and potential market characteristics through an intercept survey conducted in the San Francisco Bay Area. Three hundred respondents from 14 locations in San Francisco (N=150) and Oakland (N=150) were...
