Abstract
Addressing the current issue of not considering the influence of road geometry in the recognition of aggressive turning, a dangerous driving behavior, this paper proposes a method to eliminate the impact of road curvature on the recognition of aggressive turning based on On-Board Diagnostics (OBD) trajectory data and high-precision electronic map data. The method is validated using Jinan City as the study area. The results show that the proposed method effectively removes the influence of road curvature on the recognition of aggressive turning (left or right turns), reduces misjudgments of dangerous driving behaviors of drivers, and enhances the accuracy of identifying drivers' aggressive turning hazardous behaviors.

Description of the data and file structure
Files and variables
File: Data1_overpass.csv
Description: This dataset contains OBD data from vehicles passing through the Zhangqiu interchange, with a total of 41 records. Each record includes the Long, Lat, Number of Stars, Positioning Status, GPS Speed, Vehicle Speed, Direction, Time stamp, Mileage stamp, Fuel Level Timestamp, Revolutions, Water Temperature, and Voltage. Direction represents the instantaneous direction angle of the vehicle. They described the condition of the vehicle passing over the overpass, which is used to calculate the turning angle of the vehicle per second.
Variables
- Long: the longitude coordinate of the vehicle's location. Note: Coordinates have been randomly jittered to ensure anonymization while maintaining approximate spatial relationships. If you require further details, please contact fhx76@163.com.
- Lat: the latitude coordinate of the vehicle's location. Note: Coordinates have been randomly jittered to ensure anonymization while maintaining approximate spatial relationships. If you require further details, please contact fhx76@163.com.
- Number of Stars: the number of positioning satellites that can be received.
- Positioning Status: 0- Invalid, 1- Valid.
- GPS Speed: in kilometers per hour.
- Vehicle speed: kilometers per hour.
- Direction: The front of the car is facing from 0 to 360 degrees, with 0 being due north.
- Mileage stamp: represents the distance traveled from the ignition to the current moment, measured in meters.
- Fuel Level Timestamp:Fuel consumption from this ignition to the current fuel consumption, unit: 0.1ml.
- Rotation integer unit: Revolutions.
- Water temperature: unit: Celsius.
- Voltage:point unit: V.
File: Data2_turnleft.csv
Description: This dataset contains OBD data from vehicles turning left, with a total of 11 records. The Variables in Date 2 are the same as those in Date1, which described the condition of the vehicle turning left.
