Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the prior art. When a traffic accident occurs on the expressway, the motor vehicle driving behind often cannot grasp the traffic accident in front in time and decelerates, resulting in the occurrence of secondary traffic accidents, and When a rear-end collision occurs, problems such as failure to detect and give early warning in time

Embodiment 1

[0027] An embodiment of the present invention provides a method for preventing secondary traffic accidents on an expressway, which is used in a traffic control terminal on a road section where rear-end collision accidents frequently occur on an expressway, and the traffic control terminal is connected to a detection device set on a road section where rear-end collision accidents frequently occur. Obtain the information of motor vehicles traveling on this road segment. Due to climate change and the influence of bad weather, rear-end collision accidents often occur on some sections of the expressway. If there is no timely warning after a traffic rear-end collision accident occurs on the expressway, the visibility is low, the road is icy or the driver is not responding in time, etc. Under normal circumstances, it is also easy to cause secondary traffic accidents, which will seriously affect the passage of expressways, and usually when sending traffic accidents, the traffic managem...

Embodiment 2

[0054] A system for preventing secondary traffic accidents on expressways is provided in this embodiment, such as image 3 As shown, the system for preventing secondary traffic accidents on expressways includes:

[0055] The driving information acquisition module 1 is used to acquire the driving speeds of the first motor vehicle and the second motor vehicle on the expressway, the first motor vehicle and the second motor vehicle are located in the same lane and drive sequentially, and the first motor vehicle is ahead of the second motor vehicle . For details, refer to step S1 in Embodiment 1.

[0056] The first traveling speed judging module 2 is used for judging whether the traveling speed of the second motor vehicle is higher than the traveling speed of the first motor vehicle. For details, refer to step S2 in Embodiment 1.

[0057] The inter-vehicle distance calculation module 3 is used to calculate the inter-vehicle distance between the first and second motor vehicles wh...

Embodiment 3

[0067] The embodiment of the present invention also provides an electronic device, such as Figure 4 As shown, the electronic device may include a processor 31 and a memory 32, wherein the processor 31 and the memory 32 may be connected via a bus or in other ways, Figure 4 Take connection via bus as an example.

[0068] The processor 31 may be a central processing unit (Central Processing Unit, CPU). Processor 31 can also be other general processors, digital signal processor (Digital Signal Processor, DSP), application specific integrated circuit (Application Specific Integrated Circuit, ASIC), field programmable gate array (Field-Programmable Gate Array, FPGA) or Other chips such as programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or combinations of the above-mentioned types of chips.

[0069] Memory 32, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs, non-transi...

Abstract

The invention provides a method and system for preventing secondary traffic accidents on expressways. The method includes: obtaining and comparing the driving speeds of two adjacent motor vehicles on the same lane on the expressway. When driving, calculate the distance between the two cars, and calculate the safe distance between the two cars according to the driving speed of the two cars, and then compare whether the distance is less than the safe distance, if it is smaller than the safe distance, further judge Whether the distance between the two vehicles is reduced to 0, if so, it is determined that the two vehicles send a rear-end collision accident, generate early warning information, then obtain the display device corresponding to the location where the rear-end collision accident occurred, and send the early warning information to the display device for display. It realizes early warning when traffic accidents occur on roads with frequent traffic accidents, ensures the safety of vehicles traveling on this road section, avoids secondary traffic accidents, assists traffic management departments to discover traffic accident information in time, and improves the accident handling efficiency of traffic management departments.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a method and system for preventing secondary traffic accidents on expressways. Background technique [0002] At present, the total mileage of expressways in my country has reached more than 130,000 kilometers. With the rapid development of expressways, the time-space distance between provinces and important cities has been greatly shortened, and the inter-regional personnel, goods, technology and information have been accelerated. The speed of communication effectively reduces the cost of production and transportation, realizes the effective allocation of resources in a larger space, expands the market, and plays an important role in improving the competitiveness of enterprises, promoting national economic development and social progress. Today, the speed and convenience of expressways have also entered the lives of ordinary people, and are changing people's concept of time...
