Problems solved by technology

However, in this scheme, the alarm system is installed at the same location on the road, which makes the target vehicles of its early warning unclear and weakly targeted, which greatly reduces the effectiveness of road traffic risk early warning.
The driver of the target vehicle with risky traffic behavior is likely to ignore the warning information due to excessive speed, or misjudge the warning object and ignore the risk of his own vehicle due to too many vehicles around him, which may easily cause traffic accidents

Embodiment 1

[0022] This example discloses a traffic risk early warning system based on tweeter queues, such as figure 1 , 2 As shown, it includes: intelligent sensing device 1 , intelligent roadside terminal 2 , directional tweeter queue 3 and data center visualization platform 4 .

[0023] Intelligent sensing device 1, intelligent roadside terminal 2, directional tweeter queue 3 and data center visualization platform 4, intelligent sensing device 1, for obtaining driving information of each vehicle; intelligent roadside terminal 2 is connected with intelligent sensing device 1, for Obtain the driving information of each vehicle, and screen the vehicles with traffic risks, and send a control signal to the directional tweeter queue 3 corresponding to the selected vehicle; the directional tweeter queue 3 is connected to the intelligent roadside terminal 2 for receiving the control signal, Play long and short sounds according to the control signal and whistle regularly; the data center visu...

Embodiment 2

[0031] Based on the same inventive concept, this embodiment discloses a traffic risk early warning method based on tweeter queues, using the traffic risk early warning system in Embodiment 1, such as figure 1 , 2 shown, including the following steps:

[0032] S1 collects driving information of each vehicle;

[0033] S2 converts the vehicle driving information into corresponding traffic behavior data, and identifies, predicts and evaluates the corresponding traffic behavior based on the traffic behavior data, and determines the risky traffic behavior according to the evaluation results;

[0034] S3 judges the risky traffic behavior type and risk degree, and combines the vehicle driving information to generate a directional tweeter queue 3 control signal for the vehicle corresponding to the risky traffic behavior;

[0035] S4 The directional tweeter queue 3 plays the long and short sounds according to the control signal and whistles regularly to give an early warning to the dr...

Abstract

The invention relates to a traffic risk early warning system and method based on a tweeter queue. The system comprises intelligent sensing equipment, an intelligent roadside terminal, a directional tweeter queue, a data center visualization platform. The intelligent sensing equipment which is used for acquiring the driving information of all vehicles. The intelligent roadside terminal is used forreceiving the vehicle driving information, screening vehicles with traffic risks and sending a control signal to a tweeter queue of a target vehicle driving position; the directional tweeter queue isused for receiving the control signal and controlling tweeters on the two sides of a cab of the target vehicle according to the control signal to realize regular whistling of long and short tone matching; and the data center visualization platform is used for receiving the vehicle driving information acquired by the intelligent roadside terminal and the data of vehicles with traffic risks, and carrying out road monitoring, data storage and offline analysis. The early warning effect is obvious, the pertinence is strong, the road traffic safety can be effectively improved, and the accident occurrence probability of the expressway is reduced.

Description

technical field [0001] The invention relates to a traffic risk early warning system and method based on tweeter queues, and belongs to the technical field of traffic risk early warning. Background technique [0002] With the continuous increase of the number of national automobiles in our country and the increasing demand for long-distance transportation and travel, the state's investment in expressway construction has continued to increase. Compared with other roads, expressways have the advantages of good linearity, large flow, and fast speed, which greatly facilitate people's travel and life. However, high driving speed and large traffic flow also lead to frequent large-scale traffic accidents on expressways, especially in typical traffic road conditions such as long downhill, sharp bends, bridges and long tunnels, the accident level is often higher . Taking the long downhill road conditions as an example, because of the special road alignment characteristics, it is eas...
