Optimization of Municipal Transportation Structure Based on Collaborative Service-Take Serving the Passenger Flow of Trunk Rail Line as an Example

摘要

The collaboration of transportation modes is the inevitable direction for the development of transportation system under the current comprehensive transportation system. Guiding the collaborative development of municipal transportation system is a necessary way to solve municipal transportation problems. The efficient assignment of line passenger flow in railway hub requires the collaboration service of various modes of the municipal transportation system. Each mode has different service characteristics in the process of serving passenger flow and occupies a corresponding proportion. The analysis shows that the arrival passengers' choices of the municipal transportation mode are mainly influenced by the travel cost, travel time, transfer time, and coverage rate. This paper analyzes the relationship between municipal transportation structure and collaborative service based on collaborative service of municipal transportation system. Aiming at minimizing the deviation of the ideal and actual utilization rate of effective supply in a single mode, the objective function of overall utilization rate of municipal transportation system is constructed, and the municipal transportation collaborative service model is established. According to the variables solved by the model, the generation mechanism of optimization strategy of municipal transportation structure based on optimizing transportation service characteristic index is analyzed, and the municipal transportation structure optimization strategy aiming at collaborative service is proposed.
