Problems solved by technology

At present, the method of evaluating the operation effect of road sections and the form of presentation results are relatively single. Usually, the comparative analysis, sorting, analysis and judgment of different road sections are carried out based on indicators such as average operating speed and congestion duration, without considering the differences in actual traffic conditions under normal conditions of different road sections. It also does not consider the improvement factors of the operation effect of the road section itself, resulting in the low reliability of the comprehensive analysis results between different road sections, or even the situation of no practical application value

Abstract

The disclosure provides a multi-section operation effect evaluation method. The method comprises: step one, according to historical traffic data of road sections, automatically calculating and storingan early-warning reference value matrix and setting an early-warning threshold matrix and an assessment threshold matrix according to the early-warning reference value matrix; step two, on the basisof real-time traffic data of the road sections, determining whether traffic congestion happens automatically and eliminating a sudden congestion state; step three, after aggravation of traffic congestion, determining whether an early-warning threshold and an assessment threshold have been reached; carrying out early warning under the condition of reaching the early-warning threshold; and recordingan assessment indicator value automatically under the condition of reaching the assessment threshold; and step four, calculating an operation effect evaluation result of each road section according to the historical traffic data of the road section and the recorded assessment indicator value.

Description

technical field [0001] The disclosure relates to a multi-section operation effect evaluation method, in particular to the operation effect evaluation method of urban arterial road sections, and belongs to the technical field of intelligent transportation. Background technique [0002] The evaluation of the operation effect of the road section is one of the main functions of analysis and judgment in the traffic control platform, and it is also an important basis for the evaluation of traffic services based on the operation effect. It is of great significance to the optimization of traffic organization and the improvement of traffic management measures. At present, the method of evaluating the operation effect of road sections and the form of presentation results are relatively single. Usually, the comparative analysis, sorting, analysis and judgment of different road sections are carried out based on indicators such as average operating speed and congestion duration, without c...
