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 Pinellas Suncoast Transit Authority (PSTA) Public-Private-Partnership for Paratransit...

Shared mobility-the shared use of a vehicle, motorcycle, scooter, bicycle, or other travel mode-provides users with short-term access to a transportation mode on an as-needed basis. Shared mobility includes various travel modes and service models that meet the diverse needs of users including: carsharing, bikesharing, transportation network companies (TNCs, also known as ridesourcing and ridehailing), and others. The following section, TravelModes, provides U.S. Department of Transportation, American Planning Association, and SAE International definitions of the most common shared mobility...

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...

One-Way Electric Vehicle Carsharing in San Diego: An Exploration of the Behavioral Impacts of Pricing Incentives on Operational Efficiency

Shaheen, Susan, PhD
Martin, Elliot, PhD
Bansal, Apaar
2018

This project is a two-year evaluation of pricing/incentives applied to the one-way, all electric carsharing system operated by car2go in San Diego, CA. This system is the only electric vehicle-based, one-way carsharing system with instant access (i.e., accessible without reservation) operating in the U.S. The goal of this project is to work with car2go and the San Diego region to develop and evaluate pricing/incentive structures for their members, which improve system operational efficiency (vehicle redistribution, state-of-charge management, use of vehicles placed at public transit...

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...

Exploring Electric Vehicle Carsharing As A Mobility Option for Older Adults: A Case Study of A Senior Adult Community in The San Francisco Bay Area

Cano, Lauren

2015

By the year 2030, 57 million people will be over the age of 65 in the United States. Baby Boomers drive approximately 17% more than other age groups and are active well past retirement. This paper examines electric vehicle (EV) carsharing (short-term vehicle access) as a future alternative to vehicle ownership for older adults living on fixed incomes in a gated community to provide reduced cost mobility and eliminate vehicle maintenance hassles. The authors conducted a study of the response to the EV carsharing concept in a senior community in Northern California, between Winter 2009 and...

Shared Micromoblity Policy Toolkit: Docked and Dockless Bike and Scooter Sharing

Shaheen, Susan, PhD
Cohen, Adam
2019

Shared Micromobility – the shared use of a bicycle, scooter, or other low-speed mode – is an innovative transportation strategy that enables users to have short-term access to a mode of transportation on an as-needed basis. Shared micromobility includes various service models and transportation modes that meet the diverse needs of travelers, such as station-based bikesharing (a bicycle picked-up from and returned to any station or kiosk) and dockless bikesharing and scooter sharing (a bicycle or scooter picked up and returned to any location). Early documented impacts of shared...

Behavioral and Sociodemographic Impacts of Carsharing

Shaheen, Susan A.
Pan, Alexandra
2024

The growth of carsharing in North America since the service was first introduced in 1994 has had notable impacts on travel behaviour, including vehicle ownership and modal shift. Existing forms of carsharing (e.g., roundtrip, one-way, and peer-to-peer) alter the conventional cost structure of driving from one of fixed cost to variable cost. Multiple studies have shown that overall, carsharing users increase public transit and non-motorized modal use, with some users also selling their vehicle or postponing future vehicle purchases as a result of being a carsharing member. These modal...
