摘　　要：为引导驾驶员能快速便捷地到达兴趣点(学校、景区等),需要为其规划一条综合权值最优的路径,并在路径上布设指路标志。基于此,以交通路网模型为基础,考虑路径长度、交通饱和度、标志布设数量,定义三者综合值最小的路径为最优路径。接着从给定入口开始,采用遗传算法对到达兴趣点的路径进行自适应寻优,寻优过程中引入种群聚集度和个体偏离度对遗传算法进行改进,克服了过早收敛的缺点。最后以广州大学城为实例,利用上述算法模型得到从大学城入口至岭南印象园的指路标志布设的规划路径,并与现状导航推荐路径进行对比分析,对比结果表明,规划路径不仅考虑了路径的便捷性,同时兼顾了标志的建设成本及道路交通情况,具有科学性和可行性。In order to guide drivers to arrive at POI(schools,scenic spots,etc.)quickly and conveniently,it is necessary to plan a path with the best comprehensive weight and deploy guide signs.Based on this point,in the paper,based on a traffic road network model,considering the length of the path,traffic saturation,and the number of signs deployed,the path with the lowest comprehensive value of the three as the optimal path is defined.Then,starting from a given entrance,genetic algorithm is used to adaptively optimize the path to the POI,during the optimization process,population aggregation and individual deviation are introduced to improve the genetic algorithm,which overcomes the disadvantage of premature convergence.Finally,taking Guangzhou Higher Education Mega Center as the background,the planned path for the deployment of guide signs from the entrance of the road network to Lingnan Impression is obtained by using the above algorithm model,and compared with the current navigation recommended path.The comparison results show that the planned path not only considers the convenience of the path,but also takes the cost of guide sign and road traffic conditions into consideration,which is scientific and feasible.
