5 results about "Variable-message sign" patented technology

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.
