Abstract

The invention discloses a GPS trajectory data-based truck driving behavior assessment method. The method comprises the following steps of screening all the pieces of moving trajectory data of a to-be-detected vehicle from original GPS data; processing the moving trajectory data to obtain effective moving trajectory data; analyzing and processing the effective trajectory data to obtain an effectiveresearch trajectory; and calculating a risk driving behavior index of the effective research trajectory so as to assess the driving behavior. The invention further discloses a GPS trajectory data-based truck driving behavior assessment device. According to the method and device, mass GPS original data is mined to extract effective trajectory strokes, the main moving routes of the vehicles are recognized, and the moving trajectory data can be correctly restored through establishing driving behavior trajectory scoring mechanisms of the truck drivers with different indexes and different weights,thereby improving the stroke trajectory division accuracy, correctly putting forward driving security assessment parameters and assessing the potential risk driving behaviors and overweight driving loads.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a large truck driving behavior evaluation method and device based on GPS trajectory data. Background technique [0002] In recent years, the accident rate of large trucks in my country has been increasing year by year. This is due to the frequent traffic accidents of large trucks due to poor braking performance, overloading and speeding, and fatigue driving. Therefore, the impact of trucks on traffic safety has become an urgent problem to be solved. [0003] With the installation of a large number of GPS satellite positioning devices on large trucks, it is possible to study the driving behavior patterns of large trucks by using the track data recorded during driving. During operation, the GPS device will record spatial position (latitude and longitude), time, speed and other data at a constant sampling rate. Compared with the traditional small-scale single-point data collec...
