| 摘要: |
| 为满足客流高峰时段乘客出行舒适度要求，解决公交服务水平低的问题，基于电脑视觉模拟理论，将在车服务水平以立席密度为标准分为4个等级；引入“出行者收入”变量对现有在车感知价值模型进行优化，得到不同服务等级下平均在车感知价值，并考虑乘客感知成本，建立发车间隔计算模型.最后以天津市649路公交数据为例，对模型进行验证，通过MATLAB软件计算出客流高峰时段最优发车间隔.结果表明：高峰客流时段，乘客在车感知成本占总成本的38%~69%，验证了发车间隔计算模型中考虑乘客感知成本的必要性；在保证公交公司基本利益的情况下，最大程度地降低公交出行者的感知成本，充分体现以人为本的服务理念，研究结果可为提高公交系统的吸引力提供理论依据.

| Abstract: |
| To satisfy the comfortable demand for passengers during peak period in a low service level, the on-bus service level is divided into four grades with a standard of standing-passenger density based on the theory of computer visual simulation. An improved on-bus perceived value model of different service is proposed with the introduction of passengers' income, and the average of perceived value for different service level under different income of passengers is obtained. Furthermore, the model of departure interval considering passengers' perceived cost is formulated. The model was applied to the 649 bus route in Tianjin City, and the optimal departure time in peak period is derived based on MATLAB. Results show that it is necessary to consider passenger's perceived cost when the on-bus perceived value is 38%-69% in total during peak period. Passenger's perceived cost is cut down sharply while bus company basic interests be guaranteed. It reflects people-based service concept and may provide important scientific support with promoting the attraction of bus systems.
