Embodiment Construction

[0023] Take the evaluation of the traffic status of a main road Kaiyuan Avenue in a certain city as an example below to describe the implementation process of the inventive method in detail: Kaiyuan Avenue in a certain city is the urban traffic artery that runs through the new district of the city in the east-west direction, and the Kaiyuan Avenue traffic during morning and evening rush hours The traffic flow is relatively large, the traffic load is average during off-peak hours, and the traffic flow is relatively stable. The test case selects four intersections of Tongji Street, Jinchengzhai Street, Yongtai Street, and Shifu West Road connected from west to east on Kaiyuan Avenue. Such as figure 1 shown.

[0024] First define the average number of parking times of vehicles Vehicle Average Travel Time As the survey values ​​of two indicators of the traffic status of urban corridors, the average number of parking times of vehicles It is the ratio of the total number of re...

Abstract

The invention provides an urban passage traffic state evaluation method based on a measured vehicle.The method can solve the problem that at home and abroad, a scientific, objective and practical quantitative evaluation index and method for evaluating an urban road traffic condition do not exist.A vehicle average stop frequency S[T] and a vehicle average travel time T serve as two index investigation values of the urban passage traffic state, and vehicle traveling data of the measured vehicle passing through an urban passage to be evaluated is collected; the vehicle average stop frequency S[T] and the vehicle average travel time T when the measured vehicle passes through the urban passage to be evaluated are calculated according to the vehicle traveling data, and traffic state indexes p[i] corresponding to the two index investigation values are calculated; a comprehensive evaluation index P is calculated according to the traffic state indexes p[i] corresponding to the two index investigation values, and the grade of the traffic state of the urban passage to be evaluated is finally evaluated according to high and low of the comprehensive evaluation index P.

Description

technical field [0001] The invention relates to the field of road traffic management, in particular to a method for evaluating the traffic state of urban corridors based on measured vehicles. Background technique [0002] The use of scientific traffic organization, signal control and induction management on major passages such as urban arterial roads and expressways can effectively improve road traffic capacity and traffic efficiency, and is an effective means to alleviate urban road congestion. However, in China, there has been a lack of practical methods for evaluating the effects of traffic organization and management of major urban passageways. Most cities lack systematic evaluation of traffic organization and management technologies in the process of construction and application, making it difficult to reflect the application effects. [0003] Scholars at home and abroad have conducted preliminary research on the evaluation of traffic conditions. The evaluation indicato...
