Multi-screen display device capable of carrying out traffic flow prediction

Abstract

The invention provides a multi-screen display device capable of carrying out traffic flow prediction. The multi-screen display device capable of carrying out traffic flow prediction comprises a multi-screen display device and a prediction device connected with the multi-screen display device, wherein the prediction device comprises an acquisition module, a data pre-processing module, a data classification module, a smooothness detection module, a correlation coefficient calculation module, a threshold setting module, a space-time correlation coefficient matrix generation module, a historical correlation coefficient matrix generation module, a prediction factor selection module and a prediction model construction module which are sequentially connected. The multi-screen display device capable of carrying out traffic flow prediction is advantaged in that prediction precision is relatively high, and a constructed prediction model is with more pertinency.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a multi-screen display device capable of predicting traffic flow. Background technique [0002] Traffic flow refers to the actual number of vehicles passing through a certain section of the road per unit time, which is an important characteristic parameter to describe the traffic state. The change of traffic flow is a real-time, high-dimensional, non-linear, non-stationary random process, and changes in related factors may affect the traffic flow at the next moment. In related technologies, short-term forecasting devices have strong limitations, low forecasting accuracy, real-time forecasting fails to achieve satisfactory results, and fails to provide effective suggestions for people's real-time road choices, so traffic flow forecasting mostly stays in the Medium and long-term forecasting of traffic flow. Contents of the invention [0003] In view of the above proble...
