Abstract: The influence of different types of traffic participants on driving behaviour during a right turn at an intersection was investigated. A driving simulator was used to investigate the car's velocity and driver's gaze while conducting a right-turn manoeuvre. Five scenarios were presented randomly, with or without the presence of pedestrians and preceding or oncoming cars: driven car only, one preceding car turning right, three preceding cars turning right, one oncoming car travelling straight and one oncoming car turning left. The highest average velocity at which the driven car entered intersections was identified for the scenario with three preceding cars. The average travelling velocity in the intersection was also higher for the scenario with three preceding cars than those for other scenarios. The length of time that a driver gazed at a pedestrian, as a fraction of the total time pedestrians were visible, was the lowest for the scenario with three preceding cars. These results suggest that this scenario, among the five evaluated, might constitute the greatest danger to pedestrians at intersections.

Keywords: driving behaviour; gaze; right-turn manoeuvre; intersection; preceding car; pedestrian protection.
