This paper presents a new alert and emergency warning system concept based on a dedicated 2G or 3G cellular radio network operated along highways and motorways. By offering some of the services defined under the intelligent transport system initiative, it aims at enhancing and improving road safety. In order to locate emergency calls, the authors examine, in the context of the dedicated cellular system, the performances achieved by a time difference of arrival (TDOA) positioning technique. It then focuses on the requested physical infrastructure implantation accuracy.
