Dynamic Simulation Method for Travelling Mode Choice Behavior of Intercity Passengers Based on Two Parameters

Based on simulation methods, this paper analyzed how traffic mode characteristics and the passenger's own characteristics influenced on the choice behavior for inter-city passengers with a mathematical model. By comprehensive application of the production and income methods and introduction of the proportional coefficient, the calculation model of the travel time value was improved on the basis of the passenger attribute whether to own cars. Based on the expression function of the distribution parameters of waiting time and the elements which cannot be accurately quantified, a simulation method of the travel mode choice behavior was systematically designed for intercity passenger. In addition, this dynamic simulation approach was illustrated with the Shanghai-Hangzhou inter-city transport corridors in China. The sensitivity analysis of four parameters showed that the proposed simulation approach was accurate and valid .
