Problems solved by technology

This may lead to the situation that in a certain signal cycle, the traffic flow in one direction is large but the number of entrances is small, and the traffic flow in the other direction is small but the number of entrances is large, resulting in a waste of road resources. Cannot maximize the traffic capacity of the intersection

Embodiment Construction

[0084] In this embodiment, as figure 1 Shown is a dynamic allocation method for the entrance of a signalized intersection in a purely networked autonomous driving environment, where the signalized intersection contains signal lights; the purely networked autonomous driving environment is that all vehicles on the road are networked autonomous driving vehicles; The number of inlets is n, where n≥3;

[0085] like figure 2 As shown, the dynamic allocation method is carried out according to the following steps:

[0086] Step 0: Obtain the saturated flow of a left-turn entrance at the signalized intersection, denoted as G z ;Get the saturated flow of a straight entrance at the signalized intersection, denoted as G s ;Get the saturated flow of a right-turn entrance at the signalized intersection, denoted as G r ;

[0087] Step 1 Obtain the green light time for left-turning, straight-going green light time, and right-turning green light time at the intersection within the curren...

Abstract

The invention discloses a dynamic distribution method of signal intersection entrance lanes in a pure network connection automatic driving environment, which is suitable for a signal intersection with more than 3 entrance lanes, and all vehicles running on a road are network connection automatic driving vehicles. According to different conditions such as signal timing, lane number and vehicle number in straight, left and right directions in the current period, the method adopts a corresponding algorithm to dynamically allocate the number of entrance lanes for straight movement, left turning and right turning of vehicles in the signal period. The dynamic allocation method provided by the invention is helpful for improving the traffic capacity of the intersection and reducing the total delay of vehicles, thereby providing method support for traffic organization optimization of the signal intersection entrance lane in a pure network connection automatic driving environment.

Description

technical field [0001] The invention belongs to the field of intelligent traffic organization control, in particular to a dynamic allocation method for signal intersection entrances in a pure network-connected automatic driving environment. Background technique [0002] The signalized intersection is an important part of the urban traffic system, and the traffic condition of the signalized intersection is the key to the operation efficiency of the entire traffic system. Due to the large number of traffic conflicts and interactive disturbances at the intersection, the intersection becomes a bottleneck restricting the road capacity. In order to improve the traffic capacity of the intersection, in the prior art, the timing of signals of different phases is usually controlled by traffic lights, in order to reduce the conflict between vehicles at the intersection and improve the traffic efficiency at the intersection. However, since the number of entry lanes is fixed, it does no...
