Intelligent transport systems are developing to provide effectiveness and safety of transport management with the help of information calculations and communications between transport infrastructures and vehicles. This work studies key technologies for wireless sensor networks with the aim to provide safety and connections in road networks. To solve this problem, the work uses the fact that the vehicles move along routes with a known map, which means vehicle mobility predictability and the location of the road network. With the help of statistical analysis of vehicle detection time marks, we can obtain estimates of the distances between any pairs of sensors on the roads and construct a virtual graph that is associated with the topology of the known road map on them. Wireless sensor networks are considered to be new components for intelligent transport systems and deployed on road networks to further enhance safety and protection of driving. In this article the system of wireless sensor network autonomic passive localization for intellectual transport systems, adapted and optimized for road networks is developed. The developed localization system is reliable and realistic, taking into account time synchronization error, vehicle speed deviation and various vehicular traffic intensity, as well as the lack of sensor detection and the probability of detection duplication. The APL system shows encouraging results in the localization of a road network completely covered by vehicular traffic for estimating the distance along with one vehicle speed distribution.
