1665063 - Assessing Driver Behavior During Bicyclist Overtaking: An Integrated Simulator Study

ABSTRACT

 

This study used a driving simulator to investigate driver behavior near bike lanes. The interaction between cars and bicyclists during passing maneuvers is a key factor in bike-related accidents. The study tested two scenarios: one with a road containing a bike lane and one without. 29 participants had two driving sessions, each matching one of the scenarios. The study used car and bike simulators allowing two participants to drive simultaneously on the same road network and interact live. Driver performance was evaluated by analyzing their interactions during 30-second overtaking maneuvers. Statistical analysis assessed the bike lane's impact on driver behavior. The presence of a bicyclist led to significant changes in driver lateral movement and speed. When more space was available from the bike lane, drivers felt safer and increased speed to overtake bicycles. In conclusion, this study revealed that most drivers gradually approached bicyclists and accelerated to pass them quickly.

Learning Objectives:

Attendees can expect to learn the following from this session:
  • Evaluate the impact of bike lanes on driver behavior during overtaking maneuvers.
  • Analyze changes in driver lateral movement and speed when interacting with bicyclists on roads with and without bike lanes
  • Determine the effect of the availability of a bike lane on driver speed and passing behavior when overtaking bicycles
