2016

As of October 2014, carsharing was operating in 33 countries, five continents, and an estimated 1,531 cities with approximately 4.8 million members sharing over 104,000 vehicles. Europe, the largest carsharing region measured by membership, accounts for 46% of worldwide membership and 56% of global fleets deployed. The world’s second largest carsharing market, North America, accounts for 34% of worldwide members and 23% of vehicle fleets. In 2014, Mexico maintained the highest member-vehicle ratios (131:1), followed by 107:1 in Italy.

Zero- and Low-Emission Vehicles in U.S. Carsharing Fleets: Impacts of Exposure on Member Perceptions

2015

The California Zero-Emission Vehicle (ZEV) Mandate, adopted in 1990, was aimed at increasing the sale and dissemination of low- or zero-emission vehicles throughout the California auto market. ZEVs include plug-in hybrid vehicles (PHVs) and all-electric vehicles (EVs). In an attempt to accelerate the exposure of ZEVs in the general population, in 2001, additional credits were allotted to automakers in return for placing ZEVs into transportation networks, such as carsharing fleets. This policy is set to end in 2018. This white paper presents the results of a study that evaluated the impacts...

Information Brief: Carsharing for Business – Zipcar Case Study & Impact Analysis

Susan Shaheen, PhD and Adam Stocker
2015

Business carsharing (or corporate carsharing) is a form of carsharing that enables commercial businesses to reduce or eliminate private vehicle eets typically maintained for business purposes. It may provide exclusive-use vehicles to clients that are shared among employees and departments or it may offer shared vehicles where the client accesses the vehicles as part of a larger carsharing eet (i.e., employees use the same vehicles that are shared by individuals and/or other business members) (Shaheen and Cohen, 2012).

Since 1994, 83 carsharing programs have been deployed in the Americas — 45 are operational and 38 defunct. As of January 1, 2015, there were 20 active programs in Canada, 23 in the United States (U.S.), one program in Mexico, and one in Braziltotaling approximately 1,529,811 carsharing members sharing 22,134 vehicles in the Americas. The three largest carsharing operators in the U.S. and Canada support 95.9% and 83.2% of the total membership, respectively. Only one operator provides service in both Mexico and Brazil.

Two large all electric carsharing programs will be launching in Las Vegas, Nevada and Indianapolis, Indiana in 2014-2015.

In Las Vegas, SHIFT carsharing will be launching in late-2014. SHIFT will feature two services “CoreDrive” and “CityDrive.” CoreDrive will feature a fleet of Smart and Chevrolet Volt electric vehicles designed for short trips within downtown Las Vegas. CityDrive will feature longer-range Tesla Model S vehicles intended for longer trips around the greater Las Vegas metropolitan area. SHIFT members will also have access to a trolley service and SHIFT bikesharing....

Innovative Mobility Carsharing Outlook – Summer 2014

2014

In October 2013, TSRC hosted the inaugural Shared-Use Mobility Summit in San Francisco, a two-day event facilitating a lively dialogue among mobility providers, policymakers, governmental agencies, non-profits, affiliated industries, technologists, academics, and other stakeholders on the current state of the practice, opportunities, and obstacles to market expansion in the fields of carsharing, public bikesharing, ridesharing, ondemand ride services, employer shuttles, and related sharing economy affiliates. Day One featured sessions on industry trends, success stories, the sharing...

Peer-to-Peer Carsharing: Exploring Public Perception and Market Characteristics in the San Francisco Bay Area, California

Ingrid Ballús Armet, Susan Shaheen, PhD, Kelly Clonts, and David Weinzimmer
2014

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

Carsharing: A Guide for Local Planners

Adam Cohen, Susan Shaheen, PhD, and Ryan McKenzie
2018

Transportation issues can create seemingly no-win conflicts for planners, whether it’s dealing with traffic demand management, wrangling over parking requirements, addressing quality of life issues that accompany traffic congestion, or trying to reduce vehicle emissions to forestall climate change. A new “product-as-service” approach to vehicle use, called carsharing, is springing up in major metropolitan markets, smaller districts, and university campuses all across the country. Where the conditions are right to support carsharing, these programs can give planners another flexible...

Good Practices for Local Governments and Private Companies Driving Change Together in Urban Mobility: Lessons Learned from One-Way Carsharing

Transforming urban mobility requires integrating public with private services into a single transportation system. Local governments and private companies face the challenge of how to coordinate themselves. An emblematic example is one-way carsharing (shared use of a fleet of vehicles that are typically free-floating throughout an urban area). Surprisingly, good practices for public and private players driving this change remain relatively undocumented. This paper proposes a systematic and balanced public-private approach to foster transportation innovation management. We review both...

Evolution of E-Mobility in Carsharing Business Models

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,...
