Channelizing and signal timing method of three-entrance way intersection provided with public transportation lane

Abstract

The invention discloses a channelizing and signal timing method of a three-entrance way intersection provided with a public transportation lane. The channelizing and signal timing method comprises the following steps of: step 10) judging whether a left turning lane and a right turning lane can satisfy a combining condition: when the combining condition is satisfied, combining the left turning lane and the right turning lane, and entering a step 20); when the combining condition is not satisfied, stopping judgment; step 20), determining a position of every lane of an entrance way; step 30), channelizing the intersection; step 40), determining saturated flow of every lane; step 50), performing Webster signal timing on a road: performing the Webster signal timing on the basis of every turning flow at the intersection obtained in step 10) and the saturated flow of every lane confirmed in step 40), and checking whether the shortest green light time length when passengers cross a street. By adopting the method, a problem of insufficient space caused by arranging the public transportation lane at a cross intersection is solved, and reduction of the public transportation lane on social vehicle traffic capacity is reduced.

Description

technical field [0001] The invention belongs to the field of traffic management and control, and relates to urban road intersection channelization and intersection signal control technology, specifically, to a three-entrance intersection channelization and signal timing method with dedicated bus lanes. Background technique [0002] With the rapid development of the urban economy and the continuous expansion of the population, public transportation as a large transport capacity has become more and more popular. In order to protect the exclusive right of way of public transport vehicles, bus-only lanes are often considered for roads with more than three lanes. However, the setting of bus-only lanes not only improves the traffic capacity of buses, but also occupies the road resources of social vehicles, resulting in poor driving of social vehicles, especially the capacity of straight vehicles is greatly reduced. Therefore, how to rationally use intersection resources to set up...

AI Technical Summary

Problems solved by technology

However, in the existing road channelization method, on the premise that turning is not prohibited, the setting of bus lanes will inevitably lead to the sharing of lanes between straight-going social vehicles and other turning vehicles.
