摘要
高速公路收费到期或政府回购后可能面临路面交通拥堵、道路设施养护成本上升等诸多问题,以养护道路为目的降低收费标准继续收费是减缓地方财政压力和减少社会舆论压力的可行方法之一.本文从养护成本的角度出发,建立了双层规划模型.上层规划中将路网管理者(政府)作为领导者,以高速公路承载的交通流量最大,而路网总延误最小为目标函数,同时考虑代为管理者(运营方)的合理收益和养护成本支出的最低收费标准及道路使用者所能接受的最高收费标准.下层规划则在充分考虑道路使用者的路径选择差异性及道路拥堵对交通分布影响的基础上,建立用户均衡模型.最后采用模拟退火算法验证模型并得出具有参考意义的收费费率值.
Highway would face problems such as traffic congestion and maintenance cost rise of road infrastructure after highway toll phase expires or government repurchases. Toll extension but at a lower rate out of road conservation purpose is considered to be one feasible approach to mitigate the financial burdens and dissolve the social media pressure. From this point of view, a bilevel programming model is built. On the upper level, road network manager （government） as the leader maximizes the network traffic load and minimizes the total network delay; the lower bound of charging which ensures the reasonable profits and maintenance costs of network operator, as well as the upper bound of charging determined by the road users affordability is also considered. On the lower level, User Equilibrium （UE） model is built in full account of route choice heterogeneity and the congestion effect on traffic demand distribution. Simulated Annealing （SA） is used to validate the model and find the reference toll rate.
