Most trips in U.S. metropolitan regions are drive-alone car trips, an expensive and inefficient means of moving people. A more efficient system would allow drivers to share cars. Such a system is often less convenient for travelers, but convenience can be enhanced by deploying "smart" technologies in concert with shared-use vehicles and transit. The motivation for this research is to determine how the use of information and communication technologies can enhance flexibility and mobility-and what value travelers will place on these new transportation means.
