In order to solve the problem of traffic jams, this paper presents a solution about traffic signals area control system based on ZigBee wireless sensor network. The basic idea is to connect the area's traffic lights through ZigBee wireless sensor network according to the traffic flow during a time period where the system located. The command center coordinates and controls the length of the green signal, period and the time of the green signal on all roads through the ZigBee wireless sensor network, so that the motor vehicles which move from corresponding two-way intersections could get through with less red signal. The solution adopts TI's CC2430 RF transceiver chip and analog front-end chip CC2591 and some external circuits to design the hardware circuit of sensor nodes and the central control nodes. Then designs the applications about sensor nodes, central control nodes and management software of control center, which based on the ZigBee protocol stack. Test results show that the performance of the system, such as stability, response speed, could meet the actual demand. It can obviously improve the highway capacity.
