The development of intelligent transportation systems is one of the most important strategies for making roads safer and more efficient. The key technology underpinning all such systems, from cooperative safety systems to electronic tolling, is wireless communications. Vehicles must be able to communicate with each other, and with fixed infrastructure, in real time. One promising architecture involves forming an ad hoc network among the vehicles and taking advantage of the peer-to-peer connectivity to reduce infrastructure costs.
