A Freeway Congestion Prediction Method Fused with Historical Data and Reservation Data

Abstract

The invention discloses a highway congestion forecasting method based on historical data and reservation data. The method comprises steps: 1) a researched highway is selected and basic data are acquired, wherein the basic data altogether comprise data in four aspects: highway user reservation data, highway road network basic data, highway traffic flow historical data and highway toll policy data; 2) according to the road network basic data and the user reservation data, the highway road network is subjected to spatio-temporal partition processing, and a forecasting time period for each road section is determined; 3) the traffic amount of each road section in the highway road network in the forecasting time period is forecasted; 4) the congestion degree of each road section is forecasted; and 5) a programming language is used for realizing visual output of the congestion forecasting result. The problems that the traditional congestion forecasting method can not integrate the reservation data and can not reflect changes of the distribution law of the traffic amount brought by reservation passing in the highway road network can be solved, and more reliable basis is provided for trip guidance and highway management.

Description

technical field [0001] The invention relates to the technical field of highway congestion prediction, in particular to a highway congestion prediction method that combines historical data and reservation data. Background technique [0002] With the continuous increase of traffic volume, the congestion problem of expressways in my country (especially during the holiday peak period) is becoming more and more serious. On the first day of National Day in 2012, 26 expressways in 16 provinces across the country were congested; on the first day of National Day in 2015, 31 expressways in Guangdong Province alone were congested. In order to solve the congestion problem, the expressway management department will take certain dredging measures after the congestion occurs. Although these measures can achieve certain effects, the congestion that has occurred has caused losses to travelers and managers. Therefore, some scholars put forward the idea of ​​congestion relief before the occu...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, provide a highway congestion prediction method that combines historical data and reservation data, and breaks through the conventional highway congestion prediction method that does not consider user reservation data and cannot reflect traffic after reservation traffic It realizes the congestion prediction under the condition of expressway reserved traffic, which can effectively improve the prediction accuracy and lay the foundation for the realization of expressway reserved traffic.
