The application discloses a road state prediction method, system, equipment and storage medium, belonging to the technical field of intelligent transportation. It obtains the input traffic flow data of the current period; the input traffic flow data includes the input traffic flow density and the average vehicle speed corresponding to the input traffic flow density; the input traffic flow data includes the first input traffic flow data of the first road and the second input traffic flow data of the second road; The first road is connected to the second road; based on the input traffic data, determine the input traffic flow; obtain the average vehicle speed of the third road in the current period; obtain the pre-established road state prediction model; input the input traffic flow and average speed into road state prediction model to get the road status of the third road. It can solve the problem that the road state of the current road can only be predicted after a short period of time through the traffic density and speed of the existing vehicles on the current road, resulting in untimely prediction of road conditions. It can improve the control effect of road congestion.
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...
