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

Embodiment 1

[0027] Embodiment 1, with reference to figure 1 : A simple evaluation method for urban road congestion status, which classifies urban roads according to regional characteristics, regional characteristics and road facility scale. Select the traffic volume survey indicators related to the above characteristics from the general traffic volume survey indicators in the city. With the above survey indicators as the target, carry out traffic volume survey, and judge the state of urban road congestion through the survey. Conduct on-site statistics during a certain peak period, judge the difference between the survey results and the on-site statistics, and adjust the survey results.

[0028] Classify urban roads according to regional characteristics, regional characteristics and scale of road facilities. For example, the roads around the city center are urban arterial roads, with regional characteristics, the functional area around the city center roads is a shopping mall concentrati...

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...
