摘要

There is not yet sufficient knowledge on how people want to be driven in a highly automated vehicle. Currently, trajectory behaviour as one part of the driving style is mostly implemented as a lane-centric position of the vehicle in the lane, but drivers show quite different preferences, especially with oncoming traffic. A driving simulator study was conducted to investigate naturally-looking reactive driving trajectories on rural roads in an oncoming traffic scenario to better understand people's preferences regarding driving styles. 30 subjects experienced a static and a reactive (based on manual driving) trajectory behaviour on the most common lane widths in Germany: 2.75 m and 3.00 m. There were twelve oncoming traffic scenarios with vehicle variations in type (trucks or cars), quantity (one or two in a row) and position (with or without lateral offset to the road centre) in balanced order. Results show that the reactive trajectory behaviour leads to higher perceived safety in comparison to the static trajectory behaviour. Type of the oncoming traffic as well as lane width do have an influence on perceived safety. A small lane width (2.75 m) and oncoming trucks (type) result in lower perceived safety. There is an effect of quantity and position of oncoming traffic, too. Vehicles with a lateral offset to the road centre lead to lower safety ratings as well as more approaching vehicles. The results of the study help to design an accepted, preferred and trustfully trajectory behaviour for highly automated vehicles.
