【摘要】：露天矿传统车流规划以路径最短为基础,没有考虑路段通过能力和路段拥挤程度,车流规划结果存在超过路段通过能力的隐患。为了解决这一问题,以Wardrop均衡原理为理论依据,综合考虑路段车流、路段通过能力的影响,引入综合路阻理念,建立了露天矿车流路网均衡分配模型,实现了在传统车流规划结果基础上对路段车流进行再次优化。实验结果表明,路网均衡分配模型在不考虑路段综合路阻时,其分配结果与传统车流规划一致;当考虑综合路阻时,各路段的车流行驶总时间最小,有效避免了路段拥堵,实现了对卡车调度进一步优化,证明本模型具有更强的通用性和实用性。
[Abstract]:The traditional train flow planning of open-pit mine is based on the shortest path without considering the passage capacity and congestion degree of the road section. The result of the train flow planning has hidden trouble of exceeding the passage capacity of the road section. In order to solve this problem, based on the theory of Wardrop equilibrium principle, considering the influence of traffic flow and capacity of road section, the paper introduces the idea of comprehensive road resistance, and establishes the equilibrium distribution model of vehicle flow network in open-pit mine. Based on the results of traditional vehicle flow planning, the traffic flow of road section is optimized again. The experimental results show that the allocation results of road network equilibrium allocation model are consistent with the traditional traffic flow planning without taking into account the road sections' comprehensive road resistance, and when the road resistance is considered, the total travel time of each section is the least, which effectively avoids the congestion of the road sections. The further optimization of truck dispatching is realized, and it is proved that this model is more universal and practical.
