Abstract
Disclosed is a method for establishing and utilizing electronic tracks on roads for ground vehicles so as to ease the driving task with added safety and efficiency. Electronic tracks define traces on roads guiding the movement of a ground vehicle in as much as the same way that railroad tracks confine the movement of a train. Speed control can be achieved by using equipments detecting the driving conditions and the road environment along with the gliding action of the ground vehicle on electronic tracks. Automation in driving is thus possible, at least partially. Electronic map can be constructed consisting of many of the electronic tracks. Based upon both the static and dynamic information on roads, an electronic map is able to configure an optimal route connecting two addresses with the shortest time in traveling.
