Kurzbeschreibung (Abstract)

The Laboratory of Lighting Technology of the TU Darmstadt conducts a study consisting of an encounter situation between a standing automated vehicle (AV) and a pedestrian. The tested subjects assume the role of a pedestrian and are set in a road scene by using a virtual reality headset. The AV is equipped with an additional signalling device (two LED-stripes and two displays) in the front of the car. In total six signals are tested in 19 different variations, where different animation times, the combination of signals and different moving behaviours of the vehicle are tested. The intentions of the signals are to show to a subject, when the vehicle will start to accelerate, give a warning before accelerating and show if the road is free to cross. The moving behaviour of the subjects is recorded and decision times and crossing speeds are determined. Additionally, questionnaires are used to get a subjective rating of the level of realism of the tested scenario and the usefulness of the different lighting signals. The objective parameters like decision time and crossing speed can be compared to similar real test data to validate virtual reality as a new tool for pedestrian behaviour studies in traffic situations. Those parameters are valuable for an objective evaluation of new signal lamps in various scenarios.
