This paper offers an assessment of intersection safety evaluation through the use of different traffic micro-simulators. The aim of the paper is to evaluate the applicability of traffic simulation in the safety evaluation of typical intersections. The considered scenarios are three real cases: a roundabout, a traffic light regulated intersection and an unregulated intersection. All cases were chosen in urban areas, where statistically the number of car interactions that could potentially turn into collisions is greater. All scenarios were assessed with three different microscopic traffic simulation models that were coupled with the FHWA tool SSAM.

Abstract

This paper offers an assessment of intersection safety evaluation through the use of different traffic micro-simulators. The aim of the paper is to evaluate the applicability of traffic simulation in the safety evaluation of typical intersections. The considered scenarios are three real cases: a roundabout, a traffic light regulated intersection and an unregulated intersection. All cases were chosen in urban areas, where statistically the number of car interactions that could potentially turn into collisions is greater. All scenarios were assessed with three different microscopic traffic simulation models that were coupled with the FHWA tool SSAM.
