Abstract

The invention discloses an optimal control method for intersection group traffic flow, which resolves the defect that the smallest unit of current urban traffic control is a single intersection, which cannot satisfy the needs of actual traffic control, can realize the optimization of local traffic flow, and provides helps for micro control of traffic flow. The steps of the method are:(1) real time acquiring actual traffic flow of ''intersection group'' on roads through a ground induction coil which has been paved in a city; (2) constructing an optimal control model with a smart approach and inferring and optimizing the parameters of a controller according to real-time traffic information;(3) the controller carrying out optimal control for traffic flow according to the control model.

Description

technical field

[0001] The invention relates to a control method in the technical field of traffic flow control, in particular to a traffic flow optimization control method based on intersection groups. Background technique

[0002] The smallest unit of traditional urban traffic flow control is a single intersection. Practice has shown that it is feasible to adopt an intelligent control algorithm for an isolated intersection when the traffic flow is small. However, multiple intersections in the urban traffic network If the distance is relatively close to each other and the traffic flow in the network is large, it will not work to still use the same algorithm. In response to this situation, the present invention effectively combines and divides the crossings in the traffic network, and the crossings that are far away from each other can be considered isolated, while two to three crossings that are very close to each other are combined. Controlled as a whole, this whole is ca...
