规避超载超限货车的导航系统路径规划方法研究
Research on Path Planning Methods for Navigation Systems to Avoid Overloaded and Overweight Trucks

受到部分交通设施限载和限高的影响，货车司机需要合理的导航路径规划，该路径规划既要满足全路径交通设施限载和限高，又要实现运行的最小成本，目前缺乏高效的算法流程，因此本文对基础路网进行拓扑，提出了将道路上的货车限制信息相匹配，形成面向货车的约束路网，考虑道路约束信息对路径规划的相互关系，通过计算通行成本，标记合适道路，构建面向超载超限货车的导航系统路径规划方法。最后本文以浙江大学紫金港校区区域为例，构建了与地图相匹配的路径规划算法，展示了货车路径规划工作原理的工作逻辑。
Affected by some traffic facilities with load and height restrictions, truck drivers need reasonable navigation path planning, which should satisfy the full path traffic facilities with load and height restrictions, and also realize the minimum cost of operation, so this paper topologizes the basic road network, proposes to match the truck restriction information on the road to form a truck-oriented constrained road network, and considers the interrelationship of road constraint information on path planning. By calculating the access cost and marking the suitable roads, the path planning method of the navigation system for overloaded and overloaded trucks is constructed. Finally, this paper takes the Zijingang campus area of Zhejiang University as an example, constructs the path planning algorithm matching with the map, and shows the working logic of the working principle of truck path planning.
