A modern tram-first detector placement method for preventing vehicle queuing overflow

Abstract

The invention discloses a detector layout method of a modern tram priority for preventing queuing overflow of vehicles. The method comprises the steps of (11) collecting intersection traffic operation parameters and signal timing parameters, (12) calculating a minimum cycle length, (13) determining a layout position of a modern tram direction detector, and (14) determining the position of a queue detector in a direction different from the running direction of the modern tram. An active priority control strategy and a passive priority control strategy are employed by intersection priority pass strategies of a modern tram, in the two control strategies, the queuing state of vehicles in different directions of the running direction of the modern tram is not detected, priority is directly given to the modern tram, thus a long queue of the vehicles in other directions is caused, a queue overflow phenomenon appears, a problem of traffic jam is caused, and the problem is effectively solved by the method of the invention.

Description

technical field [0001] The invention relates to the technical field of intersection signal control in intelligent traffic technology, in particular to a modern tram priority detector layout method for preventing vehicle queuing overflow. Background technique [0002] Modern trams are an upgraded public transportation method based on traditional trams. Compared with buses, they have greater transportation capacity and are more environmentally friendly and energy-saving transportation tools. In recent years, my country's modern trams have developed rapidly, and modern trams in Beijing, Shanghai, Shenyang, Suzhou, Huai'an, Wuhan, Zhuhai and other places have all been completed and opened to traffic. By 2020, there will be more than 150 modern tram lines planned, the planned total mileage will exceed 2,500km, and the total investment will exceed 300 billion yuan. [0003] As a mode of surface rail public transportation, modern trams make priority for modern trams to pass throug...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a modern tram priority detector layout method for preventing vehicle queuing overflow, and the present invention effectively solves the active priority control strategy and passive priority control strategy adopted by the intersection priority traffic strategy of modern trams Two, the above two control strategies do not detect the queuing status of non-modern trams traveling in different directions when the traffic volume is heavy during peak hours, and directly give priority to modern trams, causing vehicles in other directions to queue too long and queuing The phenomenon of overflow, causing traffic jam problems
