Embodiment 1

[0039] see figure 1 , is a functional block diagram of an embodiment of a roadside system based on the Internet of Vehicles and capable of real-time traffic guidance in the present invention. In this embodiment, a vehicle-mounted terminal, a background control center, intelligent traffic lights, and roadside equipment form a A complete car networking system. Specifically, the roadside system in this embodiment includes a plurality of roadside devices 11, at least one intelligent traffic light 12, and a background control center 13, as well as a plurality of vehicles that can be installed on vehicles for real-time collection of vehicles Data vehicle terminal 14. Wherein, a plurality of roadside devices are arranged at intervals on both sides of the road in each road section, and intelligent traffic lights 12 are installed at crossroads or crossroads in each road section. In this embodiment, the roadside device 11 is used to collect the environmental data around it, and receiv...

Embodiment 2

[0057] Correspondingly, based on the roadside system based on the above-mentioned real-time traffic guidance based on the Internet of Vehicles, the present invention also provides a real-time guidance method based on the roadside system, which will be described in detail below in conjunction with specific embodiments and drawings illustrate.

[0058] see Figure 4 , is a schematic flowchart of an embodiment of a roadside system-based real-time guidance method of the present invention. The real-time traffic guidance method of the present embodiment is based on the roadside system in the above-mentioned embodiment, and its structure and positional relationship will not be repeated here. Specifically, the real-time traffic guidance method includes steps:

[0059] S11, the roadside device collects the vehicle data of all vehicles within its coverage area and the environmental data around the roadside device, and sends them to the background control center through the wireless com...

Embodiment 3

[0068] Due to the bad environment, or emergencies such as traffic accidents, or emergencies such as ambulances, police cars, etc., these will have a certain impact on traffic. Therefore, in order to improve efficiency, it is also possible to The environmental data is analyzed to obtain the corresponding situation, so as to provide information reference for the driving vehicle, and make corresponding countermeasures. Based on this, the present invention also provides a real-time traffic guidance method. Specifically, the real-time traffic guidance method in this embodiment includes the steps in the second embodiment above. The difference is that in this embodiment, when the roadside After the device collects vehicle data and environmental data within its range, the real-time traffic guidance method further includes steps:

[0069] The roadside equipment analyzes and judges according to the collected vehicle data and / or environmental data within its coverage area, whether there ...

Abstract

The invention discloses a real-time traffic guidance method based on Internet of Vehicles and a roadside system. The real-time traffic guidance roadside system of the invention comprises multiple roadside devices arranged at intervals along two sides of a road, intelligent traffic lamps arranged at an intersection, a vehicle-mounted terminal arranged on a vehicle, and a backstage control center, wherein each roadside device is in wireless communication connection with the backstage control center via a 3G/4G network; the roadside devices closed to the intelligent traffic lamps are in wireless communication connection with the intelligent traffic lamps; and the vehicle-mounted terminal of each vehicle driving in a coverage range of each roadside device is also in wireless communication connection with a corresponding roadside device via a wireless communication network. According to the roadside system of the invention, vehicle guidance and traffic lamp control can be realized, the display state of the traffic lamps can be adjusted according to factors such as a traffic flow and the environment in the Internet of Vehicles environment, the traffic jam phenomenon can be effectively lessened, the operational capacity of a trunk road is improved, and the operational capacity of the traffic system can be effectively improved.

Description

technical field [0001] The invention relates to the Internet of Vehicles technology, in particular to a real-time traffic guidance roadside system and a real-time traffic guidance method based on the Internet of Vehicles. Background technique [0002] As the traffic problem becomes more and more severe, the pressure on the road traffic system brought by the sharp increase of motor vehicles cannot be relieved only by improving the road infrastructure and hardware facilities, and the problem of traffic congestion is becoming more and more prominent. Development has brought enormous pressure, which not only caused economic losses, but also induced traffic accidents, leading to aggravated environmental pollution and other traffic problems. As a rather complex system, the traffic system is difficult to fundamentally solve this practical problem only in terms of vehicles or roads. Therefore, based on the Internet of Vehicles, how to combine the information of the vehicle-road-bac...
