Safety at Minor Intersections along Highways with Roadside Developments: A Case Study in Indian Context

抄録

The present paper reports an investigation on the safety deficiencies at minor investigation and identifying the crash potentials using surrogate safety measures on a typical Indian Highway having roadside developments. Intersections along the highways are one of the high risk locations for road crashes due to more number of conflicts. A safety audit of six representative minor intersections, both 3-legged and 4-legged, revealed that there are significant deficiencies at those locations. Crash potentials are estimated in terms of Post Encroachment Time for cross and rear-end collisions from manual and videography traffic survey data, which indicated that the number of critical conflicts are significantly high particularly for Vulnerable Road Users. Also more number of critical conflicts occur when major road vehicle is a 2-Wheeler. This necessitates the adoption of suitable safety treatments at/near the intersections. The methodology is beneficial in assessing the crash potentials of other intersections in developing countries context.
