【摘要】：为解决区域运输系统存在的货主超载运输导致的与公路运营方的利益冲突问题,建立了基于系统动力学的政策评价模型。该模型进一步考虑车辆严格限载和铁路介入等政策对货主时间成本的影响,通过模拟公路的货流量、路面磨损、运输能力和运输时间等环节间的互动与反馈,分析各主体利益的变化机理并给出有效策略,以协调各方利益。以曹妃甸至唐山的铁矿石运输系统为例进行仿真,结果表明:单纯的限载政策造成的货主运输成本和时间成本的增加大大高于公路运营方维护成本的降低,无法协调双方利益;通过建设铁路分流铁矿石,当铁路等级达到Ⅱ级时能同时降低双方成本,且双方累计节省的成本大于铁路建设投资,是公路严格限载下协调双方利益的有效政策。
[Abstract]:In order to solve the problem of conflicts of interest between overloaded cargo owners and highway operators in the regional transport system. A policy evaluation model based on system dynamics is established, which further considers the influence of strict vehicle load restriction and railway intervention on the time cost of the cargo owner. The interaction and feedback between the links such as transportation capacity and transportation time are analyzed and effective strategies are given to coordinate the interests of all parties. The iron ore transportation system from Caofeidian to Tangshan is taken as an example. The results show that the increase of cargo owner's transportation cost and time cost is much higher than that of highway operator's maintenance cost, which can not coordinate the interests of both parties. By diverting iron ore from construction railway, the cost of both sides can be reduced when the railway grade reaches grade 鈪，
