    摘要:

    指路标志对人们的出行有着非常良好的指引作用,良好的指路标志设计可提高驾驶人的通行效率。路网中节点处标志信息量的多少会影响驾驶员对标志信息的识读,进而影响到整个路网的通行效率。因此,通过引入节点的指路标志信息量作为惩罚系数,计算得出路段成本,建立OD间指引路径规划模型,结合A*算法,遍历整个路网,最后得出OD间的最优指引路径,通过在指引路径上增设指路信息,从而完善OD间指路标志信息的连贯性,更好的引导驾驶员做路径选择,降低路网中的交通压力。并选取甘肃省庆阳市的火车站(O点)到人民医院(D点)的区域进行实际应用与分析。

    Abstract:

    Guide signs have a very good guiding effect on people"s outgoing, and good design of guide signs can improve the driving efficiency of drivers. The amount of sign information at nodes in the road network will affect the driver"s ability to read sign information, thereby affecting the overall traffic efficiency of the whole network. Therefore, by introducing the amount of guidance sign information from nodes as a penalty coefficient, the cost of the road segment is calculated, and a guidance path planning model between ODs is established. Combined with the A * algorithm, the entire road network is traversed to obtain the optimal guidance path between ODs. By adding guidance information on the guidance path, the coherence of guidance sign information between ODs is improved, guiding drivers to make path choices better, and reducing traffic pressure in the road network. And select the area from the railway station (point O) to the People"s Hospital (point D) in Qingyang City, Gansu Province for practical application and analysis.
