Embodiment 1

[0024] Such as figure 1 As shown, the present invention provides a road signal control method, including the following steps:

[0025] A1. The vehicle terminal collects vehicle operation and road condition information in real time, and sends the vehicle operation and road condition information to the cloud platform through the control terminal;

[0026] In this step, the vehicle terminal has a wireless communication module, a positioning module (GPS, Beidou, Galileo, etc.), a voice communication module with remote voice function, a display module with a map display function, and a control module with user buttons (map zoom, map Zoom out, enter options, return).

[0027] A2. The cloud platform stores and analyzes the vehicle operation and road condition information, and generates virtual control signals;

[0028] In this step, the cloud platform maps the vehicle information to the road network model through the control center, and the platform has the optical satellite SAS system and t...

Embodiment 2

[0042] Such as Figure 4 As shown, the present invention provides another road signal control system,

[0043] The vehicle terminal is used to collect vehicle operation and road condition information in real time, and send the vehicle operation and road condition information to the cloud platform through the control terminal; the vehicle operation and road condition information includes: based on the geographic information system, the actual road network topology Mapped to the local digital city construction system; the vehicle terminal includes: a display module, a voice module, a positioning module, a vehicle controller, and a vehicle wireless module, the display module, voice module, and vehicle wireless module are connected to the vehicle controller , The positioning module is connected to the vehicle controller through the wireless module.

Abstract

The embodiment of the invention discloses a road signal control method and system. The road signal control method comprises the steps that 1, a vehicle-mounted terminal collects information of vehicle running and the road condition in real time, and sends the information of vehicle running and the road condition to a cloud platform through a control terminal; 2, the cloud platform stores and analyzes the information of vehicle running and the road condition and generates a virtual control signal; 3, the control terminal sends the virtual control signal to the vehicle-mounted terminal. By means of the road signal control method and system, virtual traffic control can be achieved, and traffic facilities do not need to be arranged on the road surface; the vehicle-mounted terminal can sense virtual traffic lights in a full-process monitoring mode, an event drive data base is set up to store feature information, and physical bases bringing convenience for traffic and transportation management department to penalize violation of regulation and for the public security department to investigate cases are provided.

Description

Technical field [0001] The invention relates to a virtual traffic signal control method and system, in particular to a road signal control method and system. Background technique [0002] Road traffic accidents have become one of the main factors that threaten the safety of human life. Road intersections, bends, bridges and other sections have always been dangerous sections with potential safety hazards. Among them, road intersections are the hubs of road traffic, and are often the high-incidence points of road traffic accidents. According to statistics, 40% of domestic traffic accidents and violations occur at intersections. [0003] In order to direct the traffic of drivers or pedestrians, promote smooth traffic and avoid traffic accidents and accidents. The transportation management department spends a lot of cost every year to build and maintain traffic signal lights and traffic signs. At the same time, it also consumes a lot of electric energy to support the operation of tr...
