Problems solved by technology

[0004] Existing expressway traffic incident detection systems and detection methods can only use the data detected by vehicle detectors to detect traffic incidents that have occurred in time, and cannot predict the time and place where traffic accidents may occur in the future
The existing traffic safety early warning system is mainly designed for vehicle drivers, and is usually integrated in the vehicle equipment. It notifies the driver whether there is a traffic safety hazard through the analysis of the current driving conditions and driving environment, but cannot provide expressway management and control. The role of the department in providing traffic safety early warning
The existing traffic accident prediction methods are

Embodiment 1

[0039] refer to figure 1 and figure 2 , the highway traffic safety early warning method provided by the present invention is realized as follows:

[0040] Step 1: Set up vehicle detectors every 1 km or so on the highway, and record the mileage of each vehicle detector set up from the starting point of the highway, and then connect each vehicle detector with the computer, so that the computer can obtain the information of each vehicle. The output data of the detector, at the same time, according to the sequence of the mileage of each vehicle detector from small to large, the serial numbers of the vehicle detectors are sequentially compiled, and the serial numbers are: 1, 2, 3, ..., n, n is the vehicle detection. The serial number of the device is a natural number, and the vehicle detector is used to collect traffic flow and traffic speed data, and send information packets including traffic flow and traffic speed data to the computer every 30 seconds,

[0041] Step 2: Establi...

Embodiment 2

[0071] like figure 1 As shown in the figure, before the highway traffic safety warning is carried out, vehicle detectors are firstly arranged on the highway, and the mileage of each vehicle detector from the starting point of the highway is recorded. The serial numbers of the vehicle detectors are compiled in sequence, and the serial numbers are: 1, 2, 3, ..., n, where n is a natural number. Then, each vehicle detector is connected to the computer, so that the computer can receive the traffic flow detection data periodically sent by the vehicle detector. Next, a vehicle detector data storage table and a safety warning scheme table are established in the computer and initialized. The safety warning scheme table consists of several data units, each data unit contains the key upstream detector number, the key upstream detector mileage, the traffic speed collected by the key upstream detector, the key downstream detector number, the key downstream detector mileage, the traffic T...

Abstract

The invention relates to a traffic security early warning method of a traffic control system on a highway; vehicle detectors are arranged on the highway; the vehicle detectors of all the vehicles are connected with computers so as to lead the computers to obtain output data of the vehicle detectors periodically and establish a data storage list of the vehicle detectors and a security early warning proposal list. After receiving an information packet, the data in the security early warning proposal list is removed; the data storage list of the vehicle detectors is updated according to the content of the received information packet; all data units in the data storage list of the vehicle detectors are searched one by one; key up stream and downstream vehicle detectors meeting the condition are determined; the time and position of possible occurrence of traffic accidents are calculated according the current collected data of the key stream and downstream vehicle detectors and writing the time and the position are written into the security early warning proposal list; if the security early warning proposal list does not have data in the period, the security early warning is not released; or early warning is released to the highway management department according to the time and the position of possible occurrence of traffic accidents in the security early warning proposal list; therefore, periodic and cycle early warning is executed.

Description

Technical field: [0001] The invention relates to a traffic safety pre-warning method applied in an expressway traffic control system, which is used to predict the time and place where a traffic accident on the expressway may break out, so as to send an alarm to the expressway traffic management and control center in advance before the accident occurs. Effect. Background technique: [0002] In the modern highway traffic management, vehicle detectors all over the highway have been used as traffic detection means, which are widely used in the detection of highway traffic flow and traffic congestion. [0003] At present, the highway traffic management and control systems widely used at home and abroad all have the function of detecting the speed and flow of traffic flow at a specific road section through vehicle detectors, and based on this, judge the traffic conditions on the road section, and timely discover the location of traffic incidents. The control center issues a traff...
