Driving Behavior Analysis Based on Trajectory Data Collected withVehicle-mounted GPS Receivers

Objective Traffic congestion is becoming an increasingly serious problem in highly urbanized areas.One reason for congestion are frequent happened traffic accidents caused by risky driving behaviors.The accurate evaluation of a driver behavior as well as safety analysis has therefore become a researchhotspot.In this paper,a new method of using the vehicle-mounted GPS model to collect the vehicletrack data and analyzing the safety of driver’s behavior is presented.In the approach,information aboutdriving over the speed limit,quick acceleration,sharp slowdown and sharp turns is extracted from the trajec-tory data.Then,the security of a drivers’behavior assessed to provide scientific evidence for the trans-portation department managers when evaluating and managing a drivers’driving skill.
