基于OpenStreetMap的城市自行车网建模与多判据路径规划

自行车交通是一种健康、绿色、环保的交通出行方式,合理地规划自行车出行路线对于满足骑行者多元化出行需求、构建安全规范的城市交通出行环境具有重要的意义.在对真实骑行者路径选择行为深入分析的基础上,提出了基于Open Street Map的城市自行车网络的构建方法及基于其上的多判据自行车路径优化的数学模型,并给出了求解该模型的一种基于聚类的最优多判据路径规划方法.实验仿真结果表明,该模型及方法能够生成满足骑行者真实需求的多判据路线方案.

OpenStreetMap Based Modeling and Multi-criteria Routing of Urban Cycleway Network

Cycling provides a healthy and environmental form of transport for most segments of the population. Planning the bicycle routes properly has important significance for satisfying the needs of cyclists with different travel purpose, and for the formation of safe and correct urban travel environments. Based on a well study of real-world cycle route choice behavior, a cycleway network is constructed based on the OpenStreetMap data, and a multi-criteria bicycle routing model and an optimum clustering-based multicriteria route planning algorithm are then proposed. The simulation results demonstrate the capability of the proposed method to generate a practical set of bicycle routes in realistic conditions.
