摘　　要：随着出行需求及汽车保有量的增加,交通拥挤愈发严重.为了缓解交通拥挤,本文针对公私合营的交通网络,考虑用户异质性,提出了对交通网络同时实行道路收费和可交易电子路票方案的混合策略,即分别对使用政府资建的公有路段和BOT模式下的私有路段的出行用户收取电子路票和费用.通过对用户在混合策略下的出行行为分析,建立了用户均衡和路票市场均衡下的变分不等式模型.接着,对交通网络的系统最优模型进行分析,得到了促使路网在用户均衡状态下达到系统最优的混合策略集合,同时给出了混合策略下系统效率损失的上界.在此基础上进一步提出了涵盖其他目标的双层规划模型,得到能实现双重目标的最优混合策略.最后,对具体路网进行数值实验,可分别得到路网中每一公有和私有路段的具体路票收取量和收费值,以及需要设置的收取总窗口数.With the increase in travel demand and car ownership,traffic congestion is becoming more and more serious.To alleviate traffic congestion,based on the user heterogeneity,this paper proposes to implement both toll and tradable credit scheme for the public-private partnership transportation network,i.e.,tolling and charging tradable credits for the users who use the government-built public roads and BOT private roads,respectively.Based on the travelers'routing behavior under this mixed strategy,we build the variational inequality model of user equilibrium and market equilibrium.Then,according to the system optimal model,the mixed strategy set can be obtained that promotes the user equilibrium flow pattern to the system optimal flow pattern,and the upper bound of system efficiency loss under mixed strategy is also derived.Furthermore,we propose two bi-level programming models covering other objectives and obtain the optimal mixed strategy.Finally,a numerical experiment on a specific road network is conducted,which can obtain the specific amount of tradable credits and charging value for each public road and BOT private road respectively,and the total number of windows for that need to be set in the road network.
