Analysis and Design of Vehicle Sharing Programs

Project 23Vehicle sharing programs (VSP’s) have been gaining ground around the world for providing an environment-friendly, socially responsible and economical mode of transport. These programs involve a fleet of vehicles positioned strategically at stations across the transportation network. Users are free to lease vehicles to complete a trip and drop the vehicle at a station close to their destination.

The shared vehicle fleet can be comprised of cars, electric vehicles or bicycles. Such systems offer innovate solutions to the larger mobility problem and can have positive impacts on the transportation system as a whole by affecting modal choice.

Strategies to better manage fleets under demand uncertainty were developed in this research effort. These strategies involve anticipative fleet redistribution that operators initiate to correct short-term demand asymmetry (since flow from one station to another is seldom equal to flow in the opposite direction). When these strategies were tested on the Singapore car sharing program, the system operated at higher reliability levels and serviced more demand than would be possible without capital improvements to the system.
