Description

Technical field [0001] The invention relates to the field of intelligent transportation, in particular to a traffic jam early warning device. Background technique [0002] Traffic flow refers to the actual number of vehicles passing through a certain section of the road per unit time, and is an important characteristic parameter describing 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 prediction devices have strong limitations and low prediction accuracy. Real-time prediction fails to achieve satisfactory results, and fails to provide effective suggestions for people's real-time road selection, so traffic flow prediction mostly stays at Medium and long-term forecasts of traffic flow. Summary of the invention [0003] In view of the above problems, the present invention provides a traffic ja...
