顾及限高限重的公路大件运输方案设计

Design on the Route Selection Scheme of Large-cargo Transportation Based on the Restriction of Height and Weight

已有的大件运输方案通常只将距离、时间、运输成本等因素作为权重值参与路径选择的分析计算,但对于超高、超重的运输车辆来说,道路的限高限重也是一个值得考虑的因素。基于经典的Dijkstra算法,结合道路网络模型,生成一个基于道路限高限重的辅助网络,并参与最短路径分析,最终得到一条综合考虑道路运输成本和限高限重的最优路径,更能适应道路网络复杂多样的情况,为大件运输的选线提供可靠的依据。

The existed large-cargo transportation scheme only takes distance,time,and transportation costs as weight values involved in analysis and calculation of path selection.However,for super-high and overweight transport vehicles,the restriction of height and weight of the road is also a consideration.By introducing the classical Dijkstra algorithm into a road network model,we generated an auxiliary network based on the restriction of height and weight to participate in the shortest path analysis.And then,we obtained an optimal path considering transportation cost,height and weight restrictions.The method can demonstrate a favourable adaptability to complex and diverse road network situations,and provide a reliable basis for the route selection of large-cargo transportation.
