The transmission of vehicle data can be real-time, which can ensure that the data is up-to-date and the road guidance given is also up-to-date, or it can be timed. The timed data does not need to be sent in real time, which saves traffic and power, and can be carried out according to the actual situation. Choose, when the road is prone to traffic jams during peak hours, you can choose to send it in real time, and when the road is relatively spacious and there are few vehicles, you can choose to send it regularly. In addition, the vehicle has the function of data supplementary transmission. If the wireless access point cannot be accessed, the data can be automatically cached, and the data will be supplemented to the traffic road network system when it is re-connected to the wireless access point.

Step S103: The traffic road network system receives the vehicle data and analyzes and processes the vehicle data.

Step S104: Send out corresponding guidance for road traffic according to the analysis and processing result. As shown in Figure 5, it also includes steps:

Step S501: Send an instruction to the road network monitoring camera to capture the speeding vehicle. To establish a normalized speed measurement mechanism;

Step S502: or

In response to the vehicle driving request for help, give avoidance guidance to other vehicles on the road where the vehicle is located, and notify relevant departments to arrive at the scene in time for processing. For example, when the car encounters an emergency, it will send an alarm to the traffic road network system. The traffic road network system analyzes the out-of-control state of the vehicle through big data, and feeds back emergency evasion guidance information to the car on the road after it may pass the current road. , guide vehicles to avoid, and the traffic network system will also notify the relevant traffic departments according to the actual situation, so that the traffic police can arrive at the scene as soon as possible.

Or when a traffic accident occurs on the road, an alarm is sent to the traffic road network system, and the traffic road network system will notify the traffic department and insurance agency as soon as possible, and at the same time, depending on the specific situation, it is necessary to notify medical resources, so that the injured or the accident can be notified. Deal with it as soon as possible to minimize losses and injuries.

Step S503: or

Issue vehicle driving instructions on blocked roads;

Step S504: or
