Bus priority signal control method for intersection adjacent to subway station

Abstract

The invention belongs to the field of urban road intersection control and relates to a bus priority signal control method for an intersection adjacent to a subway station. In full consideration of aninfluence of pedestrian crossing on such intersection bus priority signal control, the invention provides a new bus priority signal control method for an intersection adjacent to a subway station in consideration of pedestrian crossing. The method innovatively establishes a bi-level planning model for maximizing the road capacity and most optimizing pedestrian, bus passenger, and social vehicle passenger delay change benefits, solves a problem that a conventional bus priority signal control method does not take pedestrian crossing delay into account and thus influence the traffic because the pedestrians stay at the intersection for an excessive long time, thereby maximizing the total benefit of the intersection.

Description

technical field [0001] The invention belongs to the field of urban road intersection control, and relates to a method for controlling bus priority signals at intersections adjacent to subway stations. Background technique [0002] Urban road intersections are the gathering places of a large number of turning vehicles and people crossing the street, and they are also the bottleneck of urban traffic network and the source of traffic congestion. Among the urban road intersections, the ones with the highest degree of congestion and the most complicated traffic conditions are the intersections adjacent to some large public facilities and traffic stations. At such intersections, when the waiting time of pedestrians exceeds the maximum tolerable waiting time of 90s, their violations will increase significantly, which will seriously affect the traffic of vehicles and cause traffic chaos. At the same time, the bus priority signal control at the intersection is to give the bus vehicl...

AI Technical Summary

Problems solved by technology

[0003] The existing bus priority signal control methods are mainly applied to signalized intersections with simple traffic conditions. The control targets focus on the delay changes of social vehicles, bus vehicles and their passengers. No scholars in the research results of priority signal control have considered the impact of priority measures on pedestrians crossing the street

However, the existing research and analysis of pedestrian crossing delays only focus on conventional signal timing schemes, and do not consider the changes in pedestrian crossing delays when bus signal priority measures are adopted.
