Traffic road condition prediction method and device

Abstract

The invention relates to the field of traffic data processing and the field of intelligent transportation, and discloses a traffic road condition forecasting method and device based on historical data and date attribute data. The method and the device are used for solving the problems that in the prior art, traffic road condition forecasting depends on real-time data, forecasting input is complex, and a traffic road condition change rule is hard to embody on the date attribute data. The technical scheme provided by the invention is that the method comprises the steps of through mining a relation of the date attribute data and the road condition, on the basis of the road historical road condition data and the date attribute data, building a reliable and effective road condition forecasting model, i.e. completing road traffic road condition changing process similarity assessment modeling at different dates based on the date attribute date through researching historical multi-day date attribute data and the road condition data; and on the basis of the obtained traffic road condition changing process similarity model, date attribute data corresponding to a date to be forecasted, and a date attribute and road condition data corresponding to the historical date, carrying out road condition forecasting of the date to be forecasted.

Description

technical field [0001] The invention relates to the field of traffic data processing and the field of intelligent traffic, in particular to a traffic road condition prediction method and device. Background technique [0002] With the continuous increase of urban car ownership, problems such as urban traffic congestion and traffic accidents have attracted more and more attention from traffic managers and participants. In order to alleviate traffic pressure and improve traffic operation efficiency, relevant personnel in the traffic field have proposed a variety of auxiliary ideas on the basis of existing technologies. Among them, traffic road condition prediction is of great significance to improve the traffic situation. On the one hand, traffic road condition prediction can guide traffic travelers to plan travel routes reasonably and avoid congested areas; on the other hand, it can provide reliable reference for traffic managers to designate traffic management measures, so a...
