Plane intersection design variable weight comprehensive evaluation method based on rank sum ratio method

Abstract

The invention discloses a plane intersection design variable weight comprehensive evaluation method based on a rank sum ratio method. The plane intersection design variable weight comprehensive evaluation method comprises constructing an original data list, editing ranks, applying weights to different evaluation indexes, computing weighting rank sum ratios (RSRs), determining the distribution of the RSRs, computing a regression equation, classifying and sequencing files and other steps. According to the plane intersection design variable weight comprehensive evaluation method, on the basis of designing relevant evaluation indexes for urban road plane intersections under the condition of mixed traffic, variable weight factors and the rank sum ratio method are combined and used for comprehensive evaluation and sequencing of the running conditions of the multiple plane intersections. Besides, an efficiency index and a safety index are combined so that the defect of a traditional single evaluation method with efficiency as priority or safety as priority can be overcome, and meanwhile, the situation that a weight coefficient changes along with the change of an index value is considered so that the defect that a constant weight coefficient is used for the evaluation of multiple targets traditionally is overcome. The plane intersection design variable weight comprehensive evaluation method based on the rank sum ratio method has actual engineering application value in the aspects of judging the running conditions of the intersections and analyzing traffic system crucial reasons.

Description

Technical field [0001] The invention relates to a comprehensive evaluation method for the design of urban road intersections under mixed traffic conditions, in particular to a comprehensive evaluation method for variable weight design of intersections based on a rank-sum ratio method. Background technique [0002] With the economic development and the increasingly busy social activities, the process of urbanization and motorization is accelerating, and the demand for transportation is growing rapidly. The modern urban transportation system has many problems such as serious road congestion, frequent traffic accidents, and deterioration of environmental quality. Road intersections are an important part of the urban transportation network. Its smooth flow plays an important role in improving the operating efficiency of the entire transportation system. When congestion or accident occurs, it often restricts the efficiency of the entire road transportation system. Bottleneck. Therefo...
