Abstract

The invention discloses a road network dynamic traffic flow prediction method based on Simulink simulation. The method comprises the following steps that 10, basic traffic information of a to-be-predicted road network is acquired, wherein the basic traffic information comprises road network topological structure information and road network traffic operation information; 20, a road network traffic simulation system based on Simulink is created according to the acquired basic traffic information of the to-be-predicted road network; 30, dynamic road network traffic flow prediction is conducted according to the created road network traffic simulation system, and predicted traffic information is extracted. According to the prediction method, the dynamic traffic flow information operating on a large-scale city road network can be precisely predicted in real time.

Description

technical field [0001] The invention relates to a road network dynamic traffic flow prediction method, in particular to a road network dynamic traffic flow prediction method based on Simulink simulation. Background technique [0002] At present, my country's urban traffic congestion has risen from a traffic problem to a social problem of national concern, which is increasingly affecting economic and social development and the improvement of people's livelihood. The prevention and control of urban traffic congestion is extremely dependent on the accurate and real-time prediction of the dynamic traffic flow of the road network. However, due to the complex composition of my country's urban road network, various vehicle driving behaviors, and time-varying traffic demand, dynamic prediction of dynamic traffic flow is a very challenging technical problem. It is considered the most accurate traffic flow prediction method to reproduce the microscopic behavior of vehicles on complex...
