Active Targeted Traffic Guidance Information Release System

Abstract

The traffic control and guidance are two important management tools for today's urban traffic system. As a new kind of traffic guidance information service for traveler, active targeted traffic guidance information release system actively communicates with the roadside information sending devices by ZigBee short-range wireless communication technology and gets the traffic information within the guidance service region. Meanwhile, using the Global Positioning System (GPS) information and effective algorithms, system can automatically identify the location and travel direction of the vehicle and find out the targeted information. Finally, the information will release to the traveler through speech in real-time. Active targeted traffic guidance information release system can induce travelers to select the appropriate path, avoid congestion and improve travel efficiency. This paper introduces the hardware and software design of the system. Experimental test shows that the system works effectively and stably with good performance, low power consumption and high reliability.
