摘　　要：在公共交通顾客满意度评价体系中,行程时间可靠性具有极其重要的作用。基于此,本文提出了通过改进行程时间可靠性以提高公交服务水平的策略。在可靠性改进模型中,以专用车道设置费用最小为目标函数,行程时间可靠性为机会约束,建立了机会约束规划模型,并在求解时将其转化为整数规划,利用分支定界算法和遗传算法进行求解。在文章的最后,以新加坡188路公交车为例进行了案例分析。The travel time reliability is of great importance for evaluating the service level of pubfic transit. If service level is expected to effectively improve, the travel time reliability must be enhanced. This paper proposed a novel model for setting up bus lane in urban area with the chance constraint of travel time reliability. The objective function is to minimize the setting up fare of bus lane. This model is chance constraint programming model, which can be solved by branch and bound method and Genetic Algorithm. The Bus No. 188 is performed as a case study to validate the model.
