Implication

Mixed-methods analysis identifies key factors influencing discretionary lane-changing behavior in drivers, suggesting future model developments.

Key Points

  • This research aims to identify and categorize factors influencing discretionary lane-changing behavior among drivers.
  • Mixed-methods approach combining qualitative focus groups and quantitative stated-preference survey
  • Focus groups with experienced drivers generated forty lane-changing reasons
  • 220 respondents evaluated stimuli through a stated-preference survey and Exploratory Factor Analysis was performed.
  • Exploratory Factor Analysis revealed three categories of factors: Hazard & Evasive, Situational & Environmental, and Operational & Efficiency
  • Safety-critical stimuli, like stopped emergency vehicles, ranked highest among lane-changing triggers
  • The 'Hazard & Evasive' cluster emerged as the most influential in lane-changing motives.
