The invention discloses a road state prediction method, system and device and a storage medium, and belongs to the technical field of intelligent traffic. The method comprises the steps of obtaining input traffic flow data of a current time period; the input traffic flow data comprises input traffic flow density and average vehicle speed corresponding to the input traffic flow density; the input traffic flow data comprises first input traffic flow data of a first road and second input traffic flow data of a second road; the first road is connected with the second road; determining an input traffic flow based on the input traffic flow data; acquiring the average vehicle speed of the third road in the current time period; obtaining a pre-established road state prediction model; and inputting the input traffic flow and the average vehicle speed into the road state prediction model to obtain the road state of the third road. The problem that road condition prediction is not timely due to the fact that only the road state of the current road after a short time can be predicted through the traffic flow density and the vehicle speed of vehicles existing in the current road can be solved. The control effect of road congestion can be improved.
Description
technical field [0001] The present application belongs to the technical field of intelligent transportation, and in particular relates to a road state prediction method, system, equipment and storage medium. Background technique [0002] In recent years, with the increase of road vehicles, road congestion is also increasing, especially at the entrance of high-speed, where vehicles on multiple roads merge into one road, which greatly increases the probability of road congestion. Therefore, in order to To achieve intelligent management and control of roads and optimize road congestion, it is necessary to predict the state of the roads that merge into the road. [0003] Traditional road state prediction methods include: predicting the state of the current road by collecting or observing the traffic density and speed of existing vehicles on the current road. [0004] However, based on the traffic density and vehicle speed of existing vehicles on the current road, the road state...
