A method for laying out the location of priority control detectors at tram crossings

Abstract

The invention discloses a layout method for preferentially controlling the position of a detector at a tram intersection, which comprises collecting basic tram running information, dividing the distribution interval of the tram arrival time, and calculating the time for the tram to stop at the intersection and wait for a green light 1. Determining the positional relationship between the detector, the stop station and the upstream adjacent intersection, and designing the layout position of the detector in five steps. According to the intersection priority control strategy of the tram and the time distribution of the tram to the stop line, the inventive method divides the situation of the tram waiting for the green light into seven categories, proposes various calculation methods for the waiting time of the green light, and then fully considers Tram acceleration and deceleration time, station stop time and road section travel time, and based on the analysis of the positional relationship between the detector, the station and the upstream adjacent intersection, a calculation model for the layout position of the detector is established, so that the tram intersection The priority control detector layout position has the best probability to realize the priority of tram crossing.

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 are still few researches on the priority control detector location at tram intersections, and the existing research is insufficient, so it is difficult to provide guidance for quantitatively determining the detector location in engineering practice
