The invention discloses a perception intelligent driving complex traffic scene dynamic risk prediction method, and relates to the technical field of risk prediction, and the method comprises the steps: obtaining the multi-source traffic dynamic data of a target region in real time; performing space-time alignment processing on the multi-source traffic dynamic data; inputting the space-time coupling feature matrix into a pre-trained depth space-time prediction model to generate a risk thermodynamic map; calculating a dynamic risk index of each traffic sub-region, and generating a risk level distribution sequence; and triggering a self-adaptive early warning response mechanism according to the risk level distribution sequence, and dynamically adjusting operation parameters of the variable information sign and the traffic signal controller. The technical problems of frequent traffic congestion and high accident risk caused by inaccurate traffic risk prediction and difficulty in dynamic adjustment according to the real-time traffic condition in the prior art are solved, and the technical effects of accurately predicting the traffic risk and improving the safety and traffic efficiency in a complex traffic scene are achieved.

The present invention relates to a method and a device for controlling a display system of a vehicle. For this purpose, a variable message sign located on a portion of road on which the vehicle is traveling is detected. Message data representative of a message displayed on the variable message sign are obtained. Graphic content (30) in augmented reality is displayed on a display device (13) following the detection of the sign, said graphic content (30) comprising a first image (31) of a real scene located in front of the vehicle acquired by a camera on board the vehicle and a virtual graphic object (32) superimposed on the first image (31), the virtual graphic object (32) comprising a display area (320) configured to display said message data.

The present invention relates to a method and device for controlling a vehicle display system. To this end, a variable message sign located on a section of road on which the vehicle is traveling is detected. Message data representing a message displayed on the variable message sign is obtained. Augmented reality graphic content (30) is displayed on a display device (13) following the detection of the sign. This graphic content (30) comprises a first image (31) of a real scene located in front of the vehicle, acquired by a camera mounted in the vehicle, and a virtual graphic object (32) superimposed on the first image (31). The virtual graphic object (32) comprises a display area (320) configured to display said message data. (See Figure 3 for abbreviations.)

This utility model provides an intelligent variable information sign device for traffic engineering, relating to the field of traffic sign technology. It includes: a suspension frame, a main frame, information panels, turnbuckles, an electric cylinder, and a transmission link. The top of the suspension frame is fixedly connected to a traffic support rod, and the bottom of the suspension frame is connected to the main frame. A turnbuckle is connected inside the top of the suspension frame and is connected to the main frame. Three information panels are installed inside the suspension frame. An electric cylinder is installed at the bottom of the main frame, and a transmission link is connected to the bottom of each information panel. This utility model ensures the synchronicity of the rotation adjustment of the three information panels through gear meshing. It allows for rotation adjustment of the three information panels according to traffic control needs, enabling switching between two traffic signs to meet traffic control requirements. Furthermore, according to traffic control, rotating the turnbuckles causes the main frame to rise and fall, changing the height of the traffic sign and better meeting practical application needs.

The present invention relates to a Smart Traffic Electronic Enforcer on the Roads (STEER) unit and intelligent data-driven traffic control and safety information exchange infrastructure. This road safety information exchange and traffic control system were developed based on data-driven technologies and wireless communications with focus on two road safety use cases: Emergency Response Vehicle (ERV) prioritization and over speeding. An intelligent traffic controller equipped with a Variable Message Signboard (VMS) and Wireless Access Point (WAP) for communication of road safety messages, and an On-Board Unit (OBU) mounted on a vehicle, were developed, and applied to the two use cases. It was found that the system can communicate safety messages related to over speeding and ERV prioritization to motorists using the MQTT protocol over Wi-Fi and using a VMS for visual communication. Aside from road safety, the system can use road information to actuate traffic control.

This invention provides a method and apparatus for disseminating information on variable message signs (VLDLs). The method is executed by a roadside unit equipped with a VLDL controller and an information generator. The method includes: the information generator receiving a signature template corresponding to a VLDL information dissemination request from a management unit, and obtaining parameter variables corresponding to the signature template; wherein the VLDL information dissemination request is used to determine the VLDL information dissemination template type, and the VLDL information dissemination template includes template validity information and dissemination content containing wildcards, where the wildcards are placeholders for specific parameter variables; the VLDL controller performs digital signature verification and template validity verification on the signature template, and upon successful verification, matches the obtained parameter variables with the wildcards in the signature template, thereby updating the signature template based on the matched parameter variables, so that the VLDL display screen shows the information in the updated signature template. This invention ensures the security of VLDL information dissemination.

The invention relates to a toll station intelligent capacity expansion method and system based on a movable toll island, and belongs to the field of intelligent traffic. The system comprises a toll station setting data acquisition device, a toll island and toll lane automatic adjustment device, a canopy lane level dynamic information issuing device and a system decision module. The decision-making module obtains a charging lane management and control strategy according to the traffic flow data acquired by the data acquisition device in real time and the large-scale equipment special transportation event; the toll island and toll lane automatic adjusting device adjusts the number, position and sequence of toll islands, the number, position, sequence, width and toll function of toll lanes according to the toll lane management and control strategy given by the decision module. The canopy lane level dynamic information issuing device adjusts the number, the positions and the information issuing content of the variable information signs according to the charging lane management and control strategy. The problem that the traffic capacity of the entrance and the exit of the toll station is not matched with the traffic demand is solved, and the traffic capacity of the toll station is improved through an intelligent capacity expansion means.
