基于综合交通运输体系的市域快线线网规模预测

Prediction of Urban Fast-Line Network Scale Based on Integrated Transportation System

以城市内各种运输模式协调发展、供给高效、缓解交通拥堵为目标,结合城市综合交通需求,预测研究市域快线线网的合理规模。应用欧式距离不相似测度理论、三次吸引法和客流转移相结合的方法预测城市综合交通系统各运输方式向新建市域快线的客流转移量,运用"溢出+转移"客流需求分析思想,构建综合交通条件下市域快线线网规模的模型,并以2025年成都市规划为例,预测市域快线线网合理规模,验证了模型的有效性和可实施性。

Based on the goal of the coordinated development of various transportation modes in the city, the high supply efficiency and the traffic congestion alleviation, combined with the urban comprehensive traffic demand, the research is conducted for the reasonable scale of the urban fast-line network. The combination methods of the European distance non-similarity measure theory, three-time attraction method and passenger flow transfer are used to predict the passenger transfer flow of each mode of transportation of urban integrated transportation system to the newly-built fast lines. The idea of passenger flow demand analysis,“Overflow + transfer”, is used to construct the model of the urban fast-line network scale under the integrated traffic conditions. Taking the 2025-year urban planning in Chengdu City as an example, the reasonable scale of the urban fast-line network is predicted, and the validity and feasibility of the model are tested.
