Identification of Infrastructural Causative Factors for Road Accidents on Urban Arterial Roads: A Case Study of Ahmedabad

Every year approximately a 1.35million people lose their lives in a road accident, which is the world's eighth leading cause of death. There are 1.51 lakh fatalities per year in India because of road accidents, making India first across the world in terms of deaths. Accidents are caused by three factors: humans, vehicles, and infrastructure. Because humans are involved in driving, human error is generally considered to blame. However, most of the time, human error and a combination of other factors are to blame, so it is not only the driver who must accept responsibility for the accident. This research aims to identify the infrastructural element of the urban arterial road of Ahmedabad that can lead to the accident by conducting a Road Safety Audit and establishing its correlation with the past three years’ accident data. The research is validated with a closed-ended questionnaire survey. From the results, the stretches are prioritized for corrective measures. The result shows that the factors related to visibility and intersection; pedestrian and cyclist; speed and road cross-section and alignment are correlated with the accident.
