摘要
为了提高无信号交叉口主次路通行能力,增强交叉口车辆通行的高效性和安全性,提出对单车道无信号交叉口建立相应的车辆诱导模型。采用上述模型进行仿真,结果表明,在特定车流量时,有诱导情况下的交通状况远优于无诱导情况下的交通状况,平均时间延误和停车次数有了较大程度的缩短。设计出针对无信号交叉口的车辆诱导系统,可以有助于驾驶者安全高效地通过无信号交叉口,从而提高通行能力和安全性。最后,提出了以S5PV210为核心的嵌入式车载诱导系统方案,设计的系统可保证行驶的安全性。
In order to improve the traffic capability, efficiency and safety at unsignalized intersection, this paper put forward a vehicle guidance model and an algorithm for single-lane unsigualized intersection. Based on this model, simulation results between roads and average latency, roads and stopped times show that the traffic condition performs more effectively with guidance system than that without guidance system in specific traffic condition. At last, the pa- oer presented the functional design and the develonment of embedded vehicle guidanca system with SSPV210
