Abstract

The embodiment of the invention discloses a traffic information predicting method based on time series and a device thereof, relating to the communication field. In order to fast, effectively and accurately predict the traffic information, the technical scheme of the invention comprises the following steps: obtaining a statistic value of road condition data of each time window of each road in characteristic days every week according to memorized history road condition data; removing a trend term of reference road condition data of a predictive road according to the statistic value of the predictive road; obtaining a predictive equation of the predictive road according to the reference road condition data of the predictive road after removing the trend term; and obtaining predictive road condition data of the predictive road according to the predictive equation of the predictive road and real-time road condition data of the predictive road.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for predicting traffic information based on time series. Background technique [0002] Short-term traffic information prediction is one of the core issues in the construction of intelligent transportation systems. It provides the basic conditions for advanced traffic management systems (ATMS) to formulate active traffic control strategies and traffic travel information systems (ATIS) for real-time route guidance. [0003] Traffic information prediction refers to the real-time prediction of the traffic information at the next decision time t+Δt and even several moments later at time t. It is generally considered that the prediction time span from t to t+Δt does not exceed 15 minutes as short-term traffic information prediction. The results of traffic information prediction can be directly sent to the traffic information system and traffic management syste...
