A resource allocation method for intersections based on adaptive zebra crossing

Abstract

The invention discloses an intersection resource allocation method based on self-adaptive zebra crossing. Congestion adjusts the time of road traffic lights; zebra crossings include staggered upward zebra crossings and downward zebra crossings, and are composed of ground light strips. The lighting length of the ground light strips is adjustable from both sides of the zebra crossing to the center. The absolute value of the difference between the crowding degree of the pedestrian waiting area and the crowding degree of the descending pedestrian waiting area, the difference between the absolute value of the lighting length difference of the ground light strips on the ascending zebra crossing and the descending zebra crossing, and the difference in the absolute value of the crowding degree difference of the pedestrian waiting area The values ​​are positively correlated, and the sum of the lighting lengths of the upward and downward zebra crossing ground light strips remains unchanged. The invention dynamically adjusts the time length of the traffic lights and the width of the zebra crossing according to the traffic flow density and the human flow density, so as to improve the traffic efficiency.

Description

technical field [0001] The invention relates to an intersection resource allocation method, in particular to an intersection resource allocation method based on an adaptive zebra crossing. Background technique [0002] With industrialization and the improvement of people's living standards, the number of motor vehicles in my country has increased significantly. By the end of 2018, it had reached 327 million vehicles, making people's travel more convenient, but traffic congestion has become more and more serious The problem. Longer and longer traffic jams, more and more common traffic accidents, and more and more pollution emissions have undoubtedly become a huge obstacle to people's better life. At the present stage, the main causes of traffic congestion are the following three aspects: 1. The growth rate of vehicle ownership is much higher than the speed of road construction and the unreasonable road network structure; 2. The distribution of vehicles is unbalanced, with veh...

Problems solved by technology

At the present stage, the main causes of traffic congestion are the following three aspects: 1. The growth rate of vehicle ownership is much higher than the speed of road construction and the unreasonable road network structure; 2. The distribution of vehicles is unbalanced, with vehicles in the core area much higher than The peripheral area and the use time are unreasonable, and the excessive concentration of use in the morning and evening after get off work is particularly prominent in the city; 3. The focus on motor vehicles weakens non-motor vehicles and pedestrians, resulting in inconvenience and disorderly traffic.

However, the construction of speed roads cannot keep up with the increase of vehicles for a long time, and the distribution and use time of vehicles cannot be allocated and changed.

[0003] Existing solutions usually focus on improving the traffic efficiency of motor vehicles, and achieve the fastest traffic of motor vehicles by adjusting the duration of traffic lights, but they ignore the slow and random road use of pedestrians and non-motor vehicles. group
