Abstract:
    Using six types of nodes of radio sensors to structure four types of radio sensor networks, the invention forms cooperation in four layers, and accomplishes four functions. The said cooperation is: cooperation between section of road and vehicles; road junction and road junction; road junction and subarea; subarea and subarea. The said four functions are: using radio sensor networks to collect data of traffic flow in real time, fast and accurately; based on need of real time traffic flow, the invention selects self-contained signal control algorithm or cooperated signal control algorithm dynamically to generate optimal scheme for allocating time of signal for road junction; communication between road junction and vehicles make possible to redistribute spatial traffic flow; remote control end can control schemes for allocating time forcibly. There is good compatibility between the invention and current hardware of signal control system.
