Road holographic induction-based traffic service and management system

Abstract

The invention discloses a road holographic induction-based traffic service and management system. The system comprises a three-dimensional geographic information platform, a traffic situation displayunit, a road traffic information acquisition unit, a traffic event judgment analysis unit, an intersection signal timing docking unit, and a peripheral information collection and sharing unit; the three-dimensional geographic information platform is used for providing the road network map layer information of a lane level; the traffic situation display unit is used for fully presenting urban traffic operation situations from a macroscopic level, an intermediate level and a microscopic level; the road traffic information acquisition unit is used for acquiring traffic flow information on roads;the traffic event judgment analysis unit is used for judging whether a traffic event exists according to the traffic operation status of the traffic situation display unit and sending alarm information; the intersection signal timing docking unit is used for obtaining intersection signal timing information; and the peripheral information collection and sharing unit is used for collecting traffic facility information on a road network, and sharing the information displayed by the three-dimensional geographic information platform with a cloud server. With the road holographic induction-based traffic service and management system of the invention, the urban traffic conditions can be comprehensively presented from the macroscopic level, the intermediate level and the microscopic level, urban traffic management capabilities can be effectively improved, and the refinement of urban traffic information services can be realized.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a traffic service and management system based on road holographic perception. Background technique [0002] Most of the existing urban intelligent traffic command systems use 2D-GIS or dashboards to present the overall situation of urban traffic. When abnormal traffic conditions are displayed on the map, on the one hand, traffic commanders cannot accurately grasp specific traffic events (or accidents). Refined management cannot be achieved; on the other hand, the traffic operation index currently displayed by the command center is only a relatively rough road condition given by the single-directional core guide line of the road network, and cannot present accurate road condition information to pedestrians, that is, presented to The road condition information of the traveler's road section may not truly reflect the actual congestion and smoothness of the road network. ...
