This study developed a predictive model for motorcycle accidents at Malaysian urban junctions. Increased traffic flow, particularly non-motorcycle traffic on major roads, significantly elevates accident risk.

Area of Science:

  • Traffic Safety Engineering
  • Urban Planning
  • Accident Analysis

Background:

  • Nationwide motorcycle lanes aim to reduce road accidents in Malaysia.
  • Accidents at urban junctions involving motorcycles remain under-researched.

Purpose of the Study:

  • To develop a predictive model for motorcycle accidents at three-legged major-minor priority junctions in urban Malaysia.
  • To identify key factors contributing to motorcycle accidents at these junctions.

Main Methods:

  • Generalized linear modeling technique was employed.
  • Analysis focused on three-legged major-minor priority junctions in urban road networks.

Main Results:

  • Motorcycle accidents are proportional to the power of traffic flow.

  • Increased non-motorcycle and motorcycle flows at junctions correlate with higher accident rates.
  • Non-motorcycle flow on major roads, approach speed, lane width, number of lanes, shoulder width, and land use significantly influence motorcycle accidents.

    • Conclusions:

    • The developed model provides insights into factors affecting motorcycle accidents at urban junctions.
    • Findings will assist traffic engineers in designing effective junction treatments for areas without exclusive motorcycle lanes.
