城市间旅客列车的票价与流量的灵敏度分析

摘要

In this paper, the passenger demands of railways are obtained by a Log it model under the condition of competition between different traffic modes and an equilibrium model for different sorting trains is proposed. The derivatives o f demands of different sorting trains with respect to their passenger-ticket pr i ces are found through sensitivity analysis. Finally, the application of sensitiv ity analysis is illustrated with a practical example.%首先应用Logit分离模型得出城市间不同交通方式（包括铁路和公路）的客流量，在此基础上，提出了一个铁路客流量在不同旅客列车之间的均衡分配模型.然后用灵敏度分析方法分析了票价因素对于不同旅客列车客流量变化的影响关系.最后用一个实际例子，来说明灵敏度分析方法在多模式运输条件下的应用，即如何得出不同交通方式竞争条件下，铁路客运中不同旅客列车的旅客票价与其客流量之间的相互关系.
