摘　　要：为了分析公共交通整合运营模式给乘客带来的效益,对此条件下的轨道交通的最优发车间隔和票价进行了研究.采用分析优化方法,探讨了公共交通的实际乘客需求及票价成本收益,并以此为基础建立了以社会福利最大化为目标的发车间隔和票价综合优化模型,确定该模型为非线性约束最优值规划,应用可行方向法对模型进行了求解.结合算例讨论了模型的可行性和稳定性,并分析了轨道交通发车间隔和票价变化对目标函数值影响的灵敏度.For analyzing the passenger benefit of integrated operation of urban transit systems,the optimization of headway and fare of rail transit is researched.Using the analytic optimization approach（AOA）,both the practical passenger demand and the cost income of system are discussed.Based on the analyzed result,an optimization model of which the objective function aiming at maximizing social benefit is built to determine the headway and fare.This model is a non-linear constraint program,and a feasible direction search algorithm is applied to solve it.A case is studied to verify feasibility and stability of the optimization model,at the same time,the sensibilities of the effects of changes of rail transit line headway and fare on the objective function value are analyzed.
