Understanding Dangerous Intersections
What Makes an Intersection Dangerous?
A dangerous intersection is usually identified by how often and how serious vehicle crashes are at that spot. Factors that make it risky include:
- High traffic volume: More vehicles increase the likelihood of collisions.
- Poor visibility: Obstructions or lack of adequate lighting make it difficult for drivers to see other vehicles and pedestrians.
- Complex layouts: Multiple lanes, turning points, and signal phases can confuse drivers.
- Driver behavior: Aggressive driving, distraction, and non-compliance with traffic signals escalate risks.
MAG’s Weighted Intersection Safety Score (ISS)
The Maricopa Association of Governments (MAG) uses a detailed method to find and rank dangerous intersections with the Weighted Intersection Safety Score (ISS). This system looks at intersections based on three main factors:
- Crash Frequency Score (25%):
- Measures the number of crashes at an intersection over a specific period.
- Crash Severity Score (50%):
- Weighs the severity of each crash, assigning higher scores for fatal and serious injury crashes.
- Crash Type Score (25%):
- Considers the type of crashes, such as head-on collisions or side impacts, which tend to be more severe.
By combining these elements, MAG’s ISS gives a balanced view of both how often and how serious crashes are. This helps focus efforts on fixing high-risk areas.
Why This Matters for Phoenix
Using these measures in Phoenix shows intersections that regularly have high crash rates and severe accidents. Finding dangerous intersections through ISS allows city planners and traffic safety authorities to make specific improvements like better signs, enhanced lighting, and redesigned road layouts. The ultimate goal is reducing accident rates and improving overall road safety for all users.
