Problems solved by technology

However, because the traditional particle swarm optimization algorithm is easy to fall into local optimum and the convergence accuracy is not high, resulting in inaccurate final optimization results, it is still difficult to obtain good feedback in practical applications.

Embodiment Construction

[0091] Such as Figure 1 ~ Figure 2 As shown, the present invention discloses a coordinated optimization control system for regional traffic signals. The control system sets each intersection node in the road network as an intersection control agent (Agent), and each intersection control agent Both include a traffic state perception module, a traffic signal coordination optimization module, a coordination control module, an execution module and an intersection control agent. Specifically, it is as follows.

[0092] The traffic state perception module is used to obtain the traffic state of the intersection, and collect the traffic flow information on each lane in each intersection.

[0093] The traffic signal coordination and optimization module is used to analyze the traffic status of the current intersection and adjacent intersections, obtain the optimal timing scheme of each intersection and its corresponding performance indicators, and output the results.

[0094] The tra...
