Bus priority signal control system and method based on right turn and bus shared lane

Abstract

The invention discloses a bus priority signal control system and method based on right turn and shared lane, and belongs to the field of urban road traffic signal control. The entrance and exit at an entrance of a bus stop in the upstream of each entrance lane of the four entrance lanes at an intersection are separately provided with a bus stop entrance traffic light and a bus stop departure traffic light, and each bus stop is provided with receivers and entrance lane controllers which are in wireless connection. Four entrance lane controllers transmit information in a wireless manner among one another. Each bus is provided with an electronic tag, a turning button and a transmitter. The bus stop is provided with a card reader which can read the electronic tag at a distance in the upstream, and the ground where the bus stop is at is provided with no more than 3 sensing coils. The bus stop can drive at a corresponding social vehicle phase position, or drive by inserting a phase position, thus realizing bus prioritization. The insertion of bus phase position does not interfere the order of phase positions at the intersection and can reduce secondary parking of the bus.

Description

technical field [0001] The invention belongs to the field of urban road traffic signal control, and relates to a combination control technology of a timing signal and an induction signal at an intersection. Background technique [0002] In order to prevent some traffic problems such as traffic disorder, increased accidents caused by traffic congestion, and environmental pollution, a strategy of public transportation priority was proposed to attract more people to travel greenly. The Chinese Patent Publication No. is CN104408949B, and the document titled "Public Priority Signal Control Method Based on Right-Turning Vehicle and Bus Shared Lane" records that the right-turn lane is set as the right-turn vehicle and bus shared lane. Harbor-style bus stops and bus stop signal lights are installed upstream. By setting the phase difference between the main signal lights and the bus stop signal lights, the main signal lights are just right when the bus leaving the harbor-style platfo...

AI Technical Summary

Problems solved by technology

But there are also some shortcomings. For example, at the bus station, there is no consideration to prevent overflow, which will cause queues at the bus station, affect the driving of social vehicles, and cause certain delays; the signal lights are all timing, although in There is no queue at the intersection, but there is a queue at the bus stop, and the time is the same

So buses are not well prioritized
