Intersection signal control method based on public transport priority

Abstract

The invention relates to an intersection signal control method based on public transport priority. According to the method, intersection lane arranging information and real-time traffic flow information of all entrance passages are considered and combined with a vehicle jamming detection device and two groups of intersection signal lamps, a detector is triggered when an exit passage of an intersection is in a jamming state, an intervention signal control scheme is generated through automatic control of a computer to ensure timely stopping of social vehicles, a jamming area is prevented from spreading to the interior area of the intersection to affect traffic of the other direction, and at the same time public transportation vehicles are allowed to continue to run in a public transportation lane to ensure the public transport priority. Therefore, jamming of downstream road sections is prevented from affecting traffic of the intersection near upstream in an urban road peak traffic hour or when an sudden accident happens, influence of traffic jam on irrelevant traffic flow of the intersection is reduced, the public transport priority is guaranteed at the same time, and traffic circulation efficiency of a road network is improved. The invention belongs to the technical field of traffic signal control.

Description

technical field [0001] The invention relates to considering the layout of intersection lanes and the real-time traffic flow information of each entrance road, combined with a vehicle congestion detection device and two sets of intersection signal lights, triggering a detector when congestion occurs at an intersection exit road, and automatically controlling by a computer to generate Intervention signal control scheme to ensure that social vehicles can stop in time, avoid the congested area from spreading to the interior of the intersection, and affect the passage of traffic in other directions. In the event of unexpected accidents, avoid the congestion of the downstream section from affecting the traffic operation of the upstream intersection, reduce the impact of traffic congestion on the road network, and at the same time ensure the priority of public transportation and improve the traffic operation efficiency of the road network. The utility model belongs to the technical f...

Problems solved by technology

At present, the main problem that affects the use of bus-only lanes at intersections is that when the intersection exits are congested, social vehicles follow up with green lights, causing congestion in the intersection area, and traffic cannot operate

Taking roads with dedicated bus lanes at road sections and intersections as an example, buses driving in the dedicated lanes can ensure that they have priority in road sections and intersection entrances, but the actual situation is that when the intersection exits congestion , the traffic signal has not changed, and social vehicles drive into the congested exit road, causing congestion in the intersection area, and vehicles in all directions are unable to pass, resulting in the inability of public transportation priority facilities to function, and public transportation vehicles cannot pass
