The invention relates to the technical field related to vehicle navigation, and discloses an adaptive control method and system for vehicle-mounted navigation broadcast, which are suitable for urban roads, especially for vehicle navigation broadcast control in time periods with more traffic flows in morning and evening rush hours. According to the method, more appropriate lane changing sections are divided in advance before approaching the intersection, a user is guided to complete the lane changing action in advance, the situation that after approaching the intersection, the traffic flow density is increased, the vehicle speed is reduced, and then lane changing is difficult can be effectively avoided, meanwhile, the interference situation between vehicles needing crossing lane changing at the intersection is reduced, and the passing smoothness degree of the road is optimized.

The application relates to the technical field of data prediction, and provides a traffic jam prediction method for an accident high-risk area, which comprises the following steps: extracting the connection relationship between different detection points, the width of a road and the traffic flow of the detection points, determining the connection characteristic value of the detection points, and establishing the traffic flow vector and the traffic flow matrix of the detection points; establishing a connection characteristic matrix, a selectable path matrix and a traffic flow similarity matrix, and determining the fusion traffic characteristic matrix at a collection time; using a sine function to encode the collection time, obtaining the time point encoding value of the collection time, and obtaining traffic flow prediction data; and according to whether the collection time is within the rush hours of a workday, the traffic flow prediction data and the width of the road where the detection point is located, realizing traffic jam prediction. The application can improve the accuracy of traffic jam prediction.

The invention discloses an intelligent traffic regulation and control system and method based on traffic flow, and belongs to the technical field of intelligent traffic regulation and control. Comprising a real-time traffic flow sensing module, a traffic flow mode clustering analysis module, a multi-source context fusion prediction module, an intelligent signal lamp dynamic optimization module, a user feedback real-time integration module, a dynamic lane distribution module and an adaptive optimization module. Typical modes such as morning peak commuting flow and weekend purchase logistics are accurately identified, and a structured label is output; therefore, the system can implement differentiated strategies for different traffic scenes, the pattern recognition accuracy is improved, deep semantic support is provided for multi-source prediction, and the comprehensiveness and practicability of traffic state understanding are greatly enhanced.

The invention relates to the technical field of data prediction, and provides a congestion prediction method for an accident high-risk area, and the method comprises the steps: extracting the communication relation between different detection points, the width of a road, and the traffic flow of the detection points, determining the connection feature values of the detection points, and building the traffic flow vectors and a traffic flow matrix of the detection points; establishing a connection feature matrix, a selectable path matrix and a traffic flow similarity matrix, and determining a fused traffic feature matrix at the acquisition time; a sine function is adopted to encode the acquisition moment, a time point encoding value of the acquisition moment is obtained, and traffic flow prediction data is obtained; the traffic jam prediction is realized according to the traffic flow prediction data and the width of the road where the detection point is located according to whether the acquisition time is in the rush hour of the workday. According to the invention, the accuracy of traffic jam prediction can be improved.

The application provides a kind of initiative bidirectional rotating disc system based on circular intelligent underground parking lot, belongs to underground parking lot technical field, including control device, mechanical rotating disc shelter, underground parking lot body and mechanical rotating disc, when parking or taking car, control device determines the parking position of the car to be stored, control device controls mechanical rotating disc to rotate when moving downward, at the same time, control the rotation of the corresponding parking lot body rotating layer to be taken, the rotating direction of parking lot body rotating layer is opposite to that of mechanical rotating disc. The efficiency of parking and taking car is improved by half. Through the rotation of mechanical rotating disc and the rotation of a layer of underground parking lot body, they can move in the same direction, faster in and out, making the efficiency of parking higher, faster, better meeting the demand of parking and taking car during rush hour, selecting efficient bidirectional rotating mode, improving the efficiency of vehicle transportation and warehouse. Through such initiative bidirectional rotating mode, the highest efficiency of circular underground parking lot can be realized.
