一种区域性智能交通系统的研究与实现

Research and Implementation of Regional Intelligent Transportation System

基于RFID、无线传感网络、精细网格GIS等技术,提出了一个区域性智能交通模型。将无线传感节点嵌入在公共照明系统中,形成一个均匀覆盖和没有能量异构的无线传感网络,通过RFID车载终端,感知区域中每一条道路中车辆数量、类型、位置和移动速度,在准确获取道路数据的基础上,实现了"人—车—路—停车场"的相互感知,科学使用道路资源和合理分配停车资源。该方法具有很高的研究价值及应用前景。

A regional intelligent transportation model is introduced based on technologies such as RFID, wireless sensor network and fine grid blocks. In the model, wireless sensor nodes are embedded into the public lighting sys- tem to form a wireless sensor network perfectly covering a whole area without any problem of energy heterogeneous. With the help of the RFID vehicle terminal, information about the amount, type, location and velocity of the vehicles on each road can be acquired. Based on these information, people, vehicles, road and parking lot can perceive each other, which will lead to a reasonable utilization of the road and parking resource. The method has high research val- ue and good application prospects.
