SafeIntersections

Enhancing safety by identifying high-risk intersections

SafeIntersections employs a proactive, risk-based approach to identify and prioritize intersections for counter measures to improve road safety. This method considers various factors, including the monotony of the surrounding road environment, risk exposure (traffic volume), vehicle speeds, skew angle, and both horizontal and vertical alignment to assess risk. SafeIntersections then compares the risk levels of all intersections, prioritizing the highest risk ones for potential countermeasures. For each intersection, SafeIntersections provides a list of possible interventions and the expected risk reduction if specific physical or operational elements are addressed.

The advantage of SafeIntersections is that it offers practitioners a comprehensive view of intersection risks across their network. This assessment is independent of crash history, allowing for the justification of countermeasures even in locations where crashes are infrequent but potentially fatal.
