Tramcar intersection priority control detector position arrangement method

Abstract

The invention discloses a tramcar intersection priority control detector position arrangement method, and the method comprises the steps: collecting the operation basic information of a tramcar; setting a distribution section of arrival time of the tramcar; calculating the pass waiting time of the tramcar at an intersection; determining the position relation among a detector, a parking station and an upstream adjacent interaction; and arranging the position of the detector. According to a tramcar intersection priority control strategy and the distribution of time when the tramcar parks a parking line, the method enables the tramcar pass waiting condition to be divided into seven types, proposes a method for calculating various types of pass waiting time, gives full consideration to the acceleration and deceleration time of the tramcar, the parking time and the running time, takes the analysis of the position relation among a detector, the parking station and the upstream adjacent interaction as the basis, builds a calculation model for the arrangement position of the detector, enables the probability of the arrangement position to be optimal, and achieves the prior passing of the tramcar at the intersection.

Description

technical field [0001] The invention belongs to the technical field of urban rapid public transport operation and intersection signal control, and relates to a method for arranging the position of a priority control detector at an intersection of trams. Background technique [0002] With the rapid growth of the number of motor vehicles, the contradiction between the supply and demand of urban road traffic has become increasingly acute, leading to a very prominent problem of urban traffic congestion. It affects the work and life of urban residents, and is directly related to the sustainable development of my country's economy. In June 2005, Premier Wen Jiabao pointed out that "the priority development of urban public transportation is the correct strategic thinking in line with China's actual urban development and transportation development." At present, vigorously developing urban public transportation to alleviate traffic congestion has become the direction of traffic devel...

AI Technical Summary

Problems solved by technology

[0006] Some research results have been achieved on the placement of conventional bus detectors, but there is still little research on the priority control of detector locations at tram intersections, and the existing research is not enough to provide guidance for quantitatively determining the location of detectors in engineering practice
