Abstract :
In the develop history of intelligent transportation system, TTI (traffic and traveler information) service is hotpots of research all the time. Due to its low cost, wide coverage area and high bandwidth, data broadcast is usual way to publish information of real-time traffic, traffic control and dynamic traffic. This publication way has some disadvantages, such as standards´ disunity and communication´s unreliability. In this paper, we shall introduce a broadcast publication model, which can provide muti-mode communication interfaces and improve service quality of TTI system. After description of this model, we are able to evaluate its effectiveness by sufficient test results.
