Embodiment Construction

[0019] An example is given below.

[0020] Referring to the accompanying drawings, what the present embodiment discusses is an intersection of a two-lane road, and the traffic flow direction (7) shown by the arrow is set forth as an example from south to north. There are traffic lights (1) at the intersection, and before the road reaches the intersection (2), each lane of the original lane (4) is divided into two, and two new lanes are added, and after the intersection On the road section (3) behind the lights after the crossing, two new lanes have also been increased accordingly. When the green light of the traffic light (1) is on, the vehicles waiting in each lane pass through the intersection together and enter the road section (3) behind the light, wherein the vehicles on the priority lane (6) continue to move forward, while the vehicles on other lanes The vehicles then drive slowly in turn or stop and wait until the green light turns red, and the vehicles that have cross...

Abstract

The invention relates to a method for keeping traffic flow in red light. Traffic lanes are increased with equal quantity on a front-light road section (2) before a road reaches a crossroad and a post-light road section (3) after the road reaches the crossroad. When a red light is bright, vehicles stop on each traffic lane and wait, and when a green light is bright, the vehicles together pass through the crossroad to enter the behind-light road section (3), wherein vehicles on a prior traffic lane continue to go forwards, vehicles on other traffic lanes run slowly or stop to wait until the green light become red, vehicles which get across the traffic light on the prior traffic lane (6) pass over the traffic light, and then enter an original traffic lane to continue to go forwards, thereby the passing capability of traffic flow of the road is greatly improved.

Description

technical field [0001] The invention relates to a method for increasing road traffic flow, and belongs to the technical field of traffic. Background technique [0002] In the prior art, intersections are ubiquitous, and it is self-evident that they have a great negative impact on road traffic flow. Without loss of generality, take a car going straight through the intersection and setting the time of the green light and the red light equal as an example, then in 50% of the time when the red light is on, the car on the road section before the intersection stops and waits for the green light, while The road section after the intersection is vacant, and the traffic capacity of the road is completely unused. Only utilized 50% of the time when the light is green and red. It takes time for each car to start and accelerate successively after the green light is on, and the actual utilization rate must be lower than 50%. The situation is even worse when there is more than one inter...
