摘　　要：区域物流配送中车辆线路选择问题(VRP),就是最短路径的选择问题。在大区域的物流配送过程中,影响车辆最短路径选择的主要是公路网络中的交通流量和公路网络的可行路径。本文讨论了基于交通流量变化的VRP的分配模型。研究了交通流量、车速和公路技术等级之间的关系。提出用路段的技术等级作为最短路径选择的路阻权重。试验表明基于公路技术等级路段权重信息的最优路径搜索与单纯从道路长度考虑的最短路径分析相比,显然更实用也更具有实际意义。The problem of the vehicle route choice in area logistics distribution is the shortest route choice problem right away. In the process of big area logistics distribution, traffic flow and feasible highway route are the main factors to affect the shortest route choice. In this paper, a traffic flow change - based VRP distribution model is discussed firstly. Then, the relations among traffic flow, vehicle running speed and highway technology grade is studied. Finally, it proposes a method to select shortest route based on highway technology grade. Test indicates that this method is more significant than the method that only considers the road length.
