Problems solved by technology
Due to its limited length, the short lane of the exit road will create a conflict point with the adjacent through lane, causing vehicles to stop and line up on the short lane of the exit road, and drivers will jump in line at will
In turn, the exit road at the intersection is blocked, and the entrance road cannot operate normally during the green light period.

The invention discloses a method for controlling additional short lanes at an intersection to relieve the phenomenon of unreasonable utilization of road resources due to tide performance of urban traffic flows. The method mainly comprises two aspects including control of vehicles to enter an entrance short lane and leave an exit short lane. Firstly, the maximum vehicle number accommodated by the exit short lane is used as a threshold, and the queue length of vehicles in the entrance short lane is controlled according to the number of vehicles entering the entrance short lane; then, the phase difference is set reasonably according to real-time signal timing of the intersection to determine the moment of vehicles leaving the intersection in the exit short lane, so that afflux traffic flow ofthe exit short lane and straight traffic flow of the adjacent lane are least affected, and conflict points of the two traffic flows are eliminated.
Description
technical field [0001] The invention belongs to the field of road traffic control, and particularly relates to an additional short-lane control method for eliminating the conflict point of the exit road of the intersection and improving the traffic capacity of the intersection. Background technique [0002] Setting up short lanes is an important means to improve the traffic capacity of signalized intersections. However, due to the limited space conditions of short lanes, their length is limited. The phenomenon of spillover is becoming more and more common. This phenomenon is called the short-lane effect, which seriously affects the traffic capacity of the intersection and even the road network. However, the current optimization of short lanes at urban signalized intersections mainly focuses on the entrance of the intersection. For the problem of short exit lanes, the lane utilization rate is generally optimized in combination with the short lanes of the entrance, while ignor...
