Road network control method based on controllability and importance

Abstract

The invention provides a road network control method based on controllability and importance, and belongs to the technical field of traffic control, and the method comprises the steps of selecting any local road network from the whole road network of a whole city, and building a weighted directed network model for the local network; sorting the edges and the nodes in the weighted directed network model respectively by using an edge importance sorting algorithm and a node importance sorting algorithm; constructing a key road network and a standard road network according to a sorting result; obtaining a condition that the node state and the edge state are controllable at the same time; implementing traffic flow input management and control of the key road network according to traffic flow state information which is monitored and fed back by each road section and each intersection in the key road network; and summarizing traffic flow state information which is monitored and fed back by all road sections and intersections of each local road network of the whole city, and implementing traffic flow input management and control of the whole city. According to the invention, the overhead cost of road network control is reduced, the data processing amount is suddenly reduced, the data processing difficulty is reduced, and the control response speed is accelerated.

Description

technical field [0001] The invention belongs to the technical field of traffic control, in particular to a road network control method based on controllability and importance. Background technique [0002] In recent years, with the expansion of the city, the traffic flow that the transportation network needs to carry is also increasing, and traffic congestion is not uncommon, and the time waste, environmental pollution, traffic safety and other problems it brings have also begun to restrict the city in recent years. of sustainable development. [0003] The urban road network is huge and complex, and it is often impossible to control every state of the entire road network; and it is even more impossible to completely eliminate road network congestion, because the cause of road network congestion is There is a lot of randomness and uncoordination. [0004] However, after analyzing the actual situation of the road network, combined with the perception of real life, in practic...
