Festival and holiday traffic scheduling method and device based on traffic flow prediction

Abstract

The invention relates to the technical field of intelligent traffic control, in particular to a festival and holiday traffic scheduling method and device based on traffic flow prediction. The festivaland holiday traffic scheduling method based on traffic flow prediction comprises the steps: completion processing is performed on sample data from a traffic detector to obtain traffic flow data; a network model is constructed based on the traffic flow data for prediction to obtain the festival and holiday traffic flow; if a similarity value between the festival and holiday traffic flow and the historical traffic flow in a preset time period is greater than or equal to a preset threshold, a traffic scheduling scheme corresponding to the historical traffic flow is selected as a festival and holiday traffic scheduling scheme; otherwise, festivals and holidays are divided into a plurality of time periods all day long according to the change trend of the holiday traffic flow; and the historical traffic flow having the highest similarity with the traffic flow change trend in the multiple time periods is searched, and a traffic scheduling scheme corresponding to the historical traffic flowis taken as the holiday traffic scheduling scheme.

Description

technical field [0001] The present application relates to the technical field of intelligent traffic control, in particular, to a method and device for traffic dispatching on holidays based on traffic flow prediction. Background technique [0002] Holiday traffic scheduling refers to the all-day signal control plan specially formulated by the traffic management department in response to the large-scale concentrated travel of social vehicles during the holidays, resulting in a surge in traffic flow and traffic congestion. Improve the utilization rate of urban road network. [0003] In some traffic dispatching implementations, the historical traffic information of road conditions is first sampled and a traffic network model is constructed; then a method for filling missing data is proposed based on the historical traffic information, an reachable matrix is ​​constructed according to the travel time, and convolution calculation is performed to extract features; Then, the recur...

AI Technical Summary

Problems solved by technology

[0005] This application provides a holiday traffic scheduling method and device based on traffic flow forecasting. By completing the sample data, constructing a traffic flow forecasting network model, and comparing the similarity between holidays and historical dates and traffic flows and trends, the It can solve the problem that the network model training set data is incomplete and cannot automatically and quickly output matching traffic dispatching schemes based on traffic flow forecast data
