Design of Novel Intelligent Transportation System based on Wireless Sensor Network and ZigBee Technology

Intelligent transportation system (ITS) applied in the city traffic is mainly reflected in the microscopic traffic information collection, traffic control and guidance, to improve the efficiency of traffic system. Wireless sensor network has excellent characteristics, and it can provide an effective means for information collection of intelligent transportation system and can monitor the intersection in all directions of the vehicle. ZigBee is a short distance data communication network protocol and network layer based on 802.15.4. This design uses the mesh model and builds a ZigBee personal network by using ZigBee network coordinator and PAN ID. The nodes of wireless sensor network on the ZigBee module of the physical network address is sole, and it can be sent to the ITS through the physical address information. This design can improve the signal controller and intelligent public traffic system is effective and intelligent
