ABSTRACT

Safe navigation support through wireless car-to-car and car-to-curb communications has become an important priority for car manufacturers as well as transportation authorities and communications standards organizations. New standards are emerging for car-to-car communications (DSRC and more recently IEEE 802.11p).1 ere have been several well-publicized testbeds aimed at demonstrating the feasibility and e ectiveness of car-to-car communication safety; for instance, the ability to rapidly propagate accident reports to oncoming cars, the awareness of unsafe drivers in the proximity, and the prevention of intersection crashes.
