摘要
根据交通供需随机性分析,借鉴网络可靠性分析方法,提出了概率型指标——畅通可靠度的概念和计算方法,通过该指标可分析拥挤路网阻塞现象发生的可能性。同时,以路网阻塞概率分析为基础,在没有实时交通数据采集的条件下,利用统计资料及经验信息,综合考虑绕行距离,建立了基于阻塞概率分析的车辆自动导航路径优选模型。该模型可为出行者提供更接近实际情况的满意的路径及出行信息,减少用户决策的盲目性。
Based on the random analysis of traffic demand and supply , the unblocked reliability of road is used to analyze the possibility of congestion happening. At the same time, the model of optimum route selection is provided, which is based on the analysis of unblocked reliability and the circuitous length as well as the historical data and experience. The results of this optimum route selection model can provide the route guidance information for the traveler, which can reduce the blindness of travel.
