Municipal road construction period traffic jam reason discrimination method

Abstract

The invention discloses a municipal road construction period traffic jam reason discrimination method, which comprises the following steps of 1 acquiring historical traffic data, and researching traffic characteristics of a traffic system in a city main road reconstruction construction period according to four factors of a road traffic system; 2, classifying common congestion reasons of the traffic system in the municipal road construction period, and establishing a traffic system congestion reason tree model in the municipal road construction period; 3, traffic characterization characteristic analysis being carried out on various congestion reasons in the congestion reason tree model; and 4, collecting traffic data of the congested traffic road section through traffic information collection equipment arranged around the road, calculating the traffic index and judging the cause of the congested traffic road section. The method solves problems that the reason of traffic congestion during the construction period is difficult to find, efficiency is low, and management measures are not high in pertinence and poor in effect, can be used for guiding the decision-making of the traffic congestion treatment measures during the construction period in the future, and improves efficiency and scientificity of selecting the traffic treatment measures.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a method for judging the cause of traffic congestion during municipal road construction. Background technique [0002] my country has experienced the largest and fastest urbanization process in the history of the world. The urbanization rate of the permanent population has risen from 18% in 1978 to 60% in 2019. The achievements of urban development have attracted worldwide attention. However, in recent years, more and more cities in our country have suffered from many "urban diseases" including traffic congestion. Some intersections or sections of urban roads in the morning and evening peaks are caused by insufficient traffic capacity or traffic accidents. The decrease in speed and even the traffic congestion on a large-scale upstream section have affected the operating efficiency and development quality of the city. [0003] Not only the traffic congestion on normal ...

AI Technical Summary

Problems solved by technology

In particular, large-scale construction projects occupy roads for a long time and occupy a large area, which brings great traffic pressure to surrounding roads and seriously affects the normal life and travel of residents along the line.

In addition, the traffic organization during the conventional construction period mainly relies on traffic police and construction guides to conduct manual command and guidance at key road sections and intersections. The more unable to effectively deal with complex traffic conditions

[0004] At present, there are few studies on alleviating traffic congestion during the construction period of municipal roads. Most of them are researches on the problem of traffic congestion on urban conventional roads, and the causes and measures of congestion are mostly analyzed from the macro level.
