城市道路交通拥挤的区间数综合评判及对策研究

Research on Interval-number Evaluation Method and Solutions for Traffic Congestion in Urban Road Sections

针对城市道路路段交通拥挤问题,利用区间数评判理论进行了研究.根据城市道路路段交通拥挤特性和影响因素,在综合考虑诸多影响因素的基础上,建立了城市道路路段交通拥挤评价指标体系.然后利用区间数评价原理,在确定评价等级的基础上,建立了基于区间数的城市道路路段交通拥挤的综合评价模型,提出解决城市道路路段交通拥挤对策与方法,并进行了实例分析.

This paper has studied the problem of traffic jams of city road sections through the knowledge of interval-number mathematics. On the basis of considering each factor of traffic jam sof city road sections with the relevant knowledge, the multilevel interval-number evaluation of traffic jams of city road sections has been presented. This paper has alos brought forward some countermeasures and methods in resolving city road section traffic jams and has analyzed them with actual examples. They have been applied to the practical evaluation of traffic jams of city road sections in a city and some positive results have been obtained.
