A Correction Method of Traffic Allocation under the Condition of Tail Number Traffic Restriction

Abstract

The present invention discloses a traffic distribution correction method in a condition of tail number traffic control. The method comprises eight steps: obtaining the newest urban basic road network information, obtaining an initial road right table for traffic distribution, obtaining traffic zone information for traffic distribution, obtaining the newest traveling mode OD distribution matrix of a city, obtaining a vehicle tail number traffic control scheme for test, determining the proportion of two OD distribution matrixes for traffic distribution, performing multi-path-capacity limitation iteration traffic distribution, and outputting vehicle traffic volume distributed to each road section in the tail traffic control scheme. The traffic distribution correction method in condition of the tail number traffic control fully considers the national current vehicle tail number traffic control scheme to take the number of the limited vehicle tail numbers as the basis, divide the travelling mode OD distribution matrixes limited by tail numbers into unlimited tail number portion and a limited tail number portion and perform traffic distribution. The traffic distribution correction method in condition of tail number traffic control can be used for quantification test of vehicle tail number traffic control strategy enforcement effect in the urban virtual traffic test platform.

Description

Technical field: [0001] The invention relates to a method for correcting traffic allocation under the condition of tail number restriction, and belongs to the technical field of urban road network traffic allocation. Background technique: [0002] The motor vehicle tail number restriction measure is a unique traffic system in my country. It was originally born as a traffic management control strategy to alleviate urban traffic congestion. It was first implemented in Beijing during the 2007 Beijing Olympic Games test competition. Odd and even numbers are restricted. In recent years, with the rapid growth of the number of motor vehicles in major cities in my country, the traffic demand has gradually approached or even exceeded the traffic supply. The most intuitive manifestation is the traffic congestion on urban roads. Number restriction measures can alleviate traffic congestion more directly, and the effectiveness estimation of tail number restriction measures is an essential...

Problems solved by technology

[0005] The purpose of the present invention is to be completely different when the route selection result of the driver under the existing tail number restriction condition and not implementing the tail number restriction measure, yet there is no problem of the traffic distribution correction method under the tail number restriction condition at present, This paper proposes a traffic allocation correction method under the condition of tail number restriction, which fully considers the existing motor vehicle tail number restriction schemes in major cities in my country, and corrects the traffic allocation method to make up for the shortcomings of the traffic allocation correction method under the tail number restriction condition. It is of great significance to accurately and quickly realize the quantitative test of the implementation effect of the motor vehicle tail number restriction strategy in the urban virtual traffic test platform
