Simple urban road congestion statistic evaluation method

Abstract

The invention relates to a simple urban road congestion statistic evaluation method. The method comprises the following steps: (1) classifying according to the regional feature, the local feature and the scale and facility of roads; (2) selecting the traffic volume survey indicator related with the features obtained in the step (1), from the common urban traffic volume survey indicators; (3) performing a traffic volume survey according to the survey indicator selected by the step (2) so as to judge the urban road congestion; (4) performing field statistics to the same road section in one peak period; (5) comparing the statistical data obtained in the step (4) with the data obtained in the step (3) to find the difference; (6) adjusting the survey result obtained in the step (3) according to the data difference obtained in the step (5) to obtain final data; and (7) according to the final data obtained in the step (6), dividing the congestion of the urban road to be evaluated to five types, namely complete unimpeding, little congestion, some congestion, standard congestion and severe congestion; and obtaining the evaluation result. By using the method, the congestion level of the road section can be fast determined and the method corresponds to the lumped characteristic of the traffic flow.

Description

technical field [0001] The invention relates to an evaluation method, in particular to a simple statistical evaluation method of urban road congestion state, which is suitable for rapid traffic volume investigation in large and medium-sized cities in my country. Background technique [0002] my country is in a period of rapid economic growth, urban traffic volume increases rapidly, and the phenomenon of urban traffic congestion is ubiquitous. However, the construction of urban road traffic infrastructure is slow, and the level of traffic management is increasing very slowly. Congestion, as the main problem that hinders the rapid development of cities, affects the smooth progress of urban planning, causes huge economic losses, and increases urban exhaust and noise. In addition, urban congestion also affects people's living standards and working environment. In order to solve the traffic congestion, the country has proposed a series of guidelines and policies, and it is expe...

Problems solved by technology

[0006] Generally speaking, the urban road congestion solution method applicable to my country's national conditions has not been released, and one of the main reasons is that the state evaluation method of urban traffic congestion is not perfect. The present invention promptly proposes a simple and effective urban road congestion state evaluation method
