Abstract

The invention discloses a road traffic cooperative control method for an urban central area. The method comprises the following steps of: by taking a biological synergy phenomenon as a background, comprehensively considering each traffic factor of the urban central area, connecting a plurality of adjacent signal intersections in the area for cooperative control through a controller area network (CAN) bus data communication technology, performing immune adjustment on the individual population of the plurality of intersections, and enabling traffic environment pressure change and traffic signal systems (traffic signal control synergy bodies) applied to the traffic environment to be respectively corresponding to targets for resolving problems and solutions of the problems. By adoption of a multi-mode immune co-evolution mechanism, a traffic cooperation optimized target function is that the delay sum of vehicles at the intersections is the minimum, so that the traffic parameters such as the period, the green ratio and the phase difference are controlled, the target cooperation and evolution fusion among the signal intersections are formed, and the efficiency of solving the traffic problems in the urban central area is effectively improved.

Description

technical field

[0001] The invention belongs to a road traffic organization management method, in particular to a road traffic cooperative control method applicable to urban central areas. Background technique

[0002] With the rapid development of economic globalization and science and technology, transportation, as an important aspect of social and economic life, plays an important role in ensuring the normal operation of the social and economic system, and has become an indispensable and important part of people's lives. In the past 20 years, countries around the world have successively established transportation networks extending in all directions, but the growth rate of transportation vehicles is much higher than that of roads and other transportation facilities, resulting in traffic congestion, traffic accidents, environmental pollution, energy shortages, etc. The problem has become a common problem faced by all countries in the world, and it has also caused huge mate...
