Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a traffic flow monitoring and forecasting system. 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 problems, the present inventi...
