Description

Technical Field [0001] The present invention relates to an incident monitoring system and method based on vehicle information recognition,

In particular, the present invention relates to a system and method for monitoring an unexpected situation through recognition of an unexpected vehicle information. More particularly, the present invention relates to a system and method for monitoring an unexpected situation, The present invention relates to a surveillance system and method for monitoring an unexpected situation in real time using information.

An unexpected and unexpected series of incidents on the road is a traffic accident, a road construction, a blockage of a road due to a breakdown of a vehicle, the presence of obstacles on the road, road maintenance work, or other unusual events If an unexpected situation occurs, the normal flow of the traffic flow is broken, the capacity of the road is decreased, and the traffic congestion and the air pollution cause enormous social and economic losses. Therefore, in order to effectively cope with an unforeseen unexpected situation, it is necessary to detect the unexpected sudden situation more quickly.

Recently, in the transportation sector, Intelligent Transportation Systems (ITS) projects for traffic safety and environmental improvement have been actively carried out in order to reduce the risk of traffic accidents and solve traffic congestion, . In the ITS project, an extreme situation detection system is being built as one of the key measures to mitigate traffic congestion. Most traffic information centers in charge of ITS operation recognize the unexpected situation through an unexpected situation detection system and provide related information through VMS.

Existing situation detection algorithms include pattern recognition techniques, statistical techniques, and artificial neural network models. Among them, pattern recognition is the most commonly used technique for recognizing sudden situation. The pattern recognition technique directly compares the difference of traffic patterns to determine whether an unexpected event occurs. As a representative pattern recognition technique, there is a CA algorithm that is most widely used as a criterion for comparing the performance of other algorithms because it has a simple structure and is easy to apply in the field and has a reliable outcome of detecting an unexpected situation. In addition, the APID (All Purpose Incident Detection) algorithm is based on the California algorithm, which compares the share and speed of the two upstream and downstream points, and performs both the compression wave test and the persistence test (four cycles every 30 seconds).

 In the statistical algorithm, the detection data is processed through various statistical analysis and the result is used to grasp the unexpected situation. Representative statistical algorithms include the Standard Normal Deviate (SND) algorithm and the Bayesian algorithm developed by the Texas Transportation Institute (TTI) in the early 1970s. The Bayesian algorithm uses the difference in occupancy time between two probes similar to the algorithm based on the California algorithm, but is used to calculate a large difference in occupancy due to recurrence of accidents or traffic congestion. The off-line result of this algorithm is useful for accident detection rate and false alarm signal, but it takes a long time to detect because it takes much time to classify the accident.

Among the various extreme situation detection algorithms, the extreme situation detection system which is applied in most domestic and international ITS is the two-point traffic parameter (vehicle occupancy rate, etc.) collected through the vehicle detectors (image detectors such as image detectors and loop detectors) ), And recognizes the situation as an unexpected situation when the traffic parameter differs by more than a predetermined value.

Conventional technologies have problems of misjudgment due to traffic congestion and temporary traffic flow fluctuation. Even if the situation is not an unexpected situation, there may be a difference in traffic parameters (speed, occupancy, etc.) between the two points in the process of traffic congestion or the solution of the traffic congestion. Also, Etc.) may occur. Due to these problems, the traffic information center has constructed an unexpected situation detection system, but sometimes it does not operate. Further, the conventional technology is limited to a level for judging whether or not an unexpected situation occurs on the road, and has a problem that it is not a level that can recognize the information (vehicle number) of the vehicle that caused the unexpected situation.
