Influence of Public Bus Driver’s Driving Behaviors on Passenger Fall Incidents: An Analysis Using Digital Tachograph Data

Table 1

Dangerous driving behavior calculation criteria.

Types	Calculation criteria
Speeding	Exceeding the road speed limit by 20 km/h
Sudden acceleration	Accelerating more than 6.0 km/h per second at speeds of 6.0 km/h or more
Sudden start	Accelerating more than 8.0 km/h per second at speeds below 5.0 km/h
Abrupt deceleration	Decelerating more than 9.0 km/h per second at speeds of 6.0 km/h or more
Abrupt stop	When the speed is reduced to 5.0 km/h or less by decelerating more than 9.0 km/h per second
Abrupt turn left or turn right	Sharp turn to left/right (accumulated rotation angle is in the range of 60–120°) within 4 s at a speed of 25 km/h or more
Abrupt U-turn	Drive left/right (range 160–180°) in 8 s with a speed of more than 20 km/h
