Overview

Microscopic study reveals factors influencing bicycle fatalities in urban traffic, indicating critical safety implications.

Key Points

  • The study aims to identify factors contributing to bicycle fatalities in urban mixed-traffic environments.
  • Conducted a microscopic crash investigation at road segments in Delhi, India.
  • Developed count data models to analyze the effect of road characteristics on bicycle fatalities.
  • Included zonal-level attributes to assess their influence on bicycle safety.
  • Cars and heavy commercial vehicles are the primary contributors to bicycle fatalities.
  • Increases in bicycle and HCV volume raise the likelihood of fatalities, while bus volume reduces it.
  • Recreational land use correlates with a higher probability of bicycle fatalities.
  • Safety-in-Numbers concept validated, although variability in bicycle volume impact needs further analysis.
