Abstract:

In almost all countries, road accident statistics show that pedestrians share higher percentage in road user fatalities which makes the pedestrian motor vehicle crashes more significant. Though the parameters like traffic volume and pedestrian count are the main determinants, Built Environment along the roads has indirect effect on risk of accident occurrences. This paper deals with the impact of built environment elements on pedestrian-motor vehicle collision in the city of Tiruchirappalli, Tamilnadu, India. It includes the use of pedestrian road accident data, hot spot identification, environment audit, land use classification and logistic regression model for analysis. The study also includes the use of the model in identifying the percentage of contribution of each built environment element in accident occurrence.
