Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] Such as figure 1 Shown, the highway vehicle abnormal behavior detection method based on GPS data in the preferred embodiment of the present invention, this method comprises the following several parts:

[0039] The first stage is the data acquisition stage, which is to obtain vehicle dynamic information through the vehicle GPS device, including vehicle ID, feedback time, vehicle latitude and longitude, etc. These data mainly show two characteristics: one is that for each vehicle, the positioning data is a time series data, which can obtain the continuous movement characteristics of the vehi...

Abstract

The invention discloses a method for detecting abnormal behavior of expressway vehicles based on GPS data, which includes: data acquisition stage: obtaining vehicle dynamic information through a vehicle-mounted GPS device; data processing stage: converting vehicle dynamic information through coordinate transformation to obtain Coordinate data; feature extraction stage: extract the converted vehicle dynamic parameter features according to the coordinate data at different times; recognition and early warning stage: use the standard deviation method and neural network to identify vehicle behavior according to the vehicle dynamic parameter features, and identify Carry out graded early warning for abnormal vehicle behavior. The present invention can realize the real-time detection of the abnormal driving behavior state of the vehicle on the expressway only by using the vehicle-mounted GPS device, which helps to prevent secondary accidents on the expressway, reduces expressway congestion, reduces vehicle delays, and improves expressway operating efficiency. In order to achieve the goal of low-carbon and safe travel.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for detecting abnormal behavior of expressway vehicles based on GPS data. Background technique [0002] Expressway traffic congestion and traffic safety have become an important research topic in the field of transportation. Abnormal vehicle behavior is the main reason for expressway congestion and traffic accidents. The abnormal behaviors of expressway vehicles mainly include speeding, low-speed driving, reverse driving, emergency braking, temporary parking, emergency parking, abnormal trajectory, etc. There is a process of change for the above abnormal behaviors of the vehicle, and finally a stable state. [0003] If it is possible to detect vehicle behavior and prompt early warning during the process of abnormal behavior changes of the vehicle, when the vehicle reaches the final state, the state of the vehicle can be judged immediately and the final warning ...
