Safety (Collision Concentrations)
Goal
Operate and maintain the County's 3,200 centerline miles (7,400 lane-miles) of streets, highways, and bridges to provide for safe operating conditions.
Desired Results
- Reduce the number of County unincorporated collision concentration locations by 10% by 2020.
Analysis
- Collision concentration locations are identified by comparing the number of accidents that occurred at a location with a set of criteria which identify locations with a recurrence of specific collision patterns over the latest 12-month period and any consecutive 36-month period within our five years of data. The top 5 percent locations are then referred to specific sections in Traffic and Lighting or other Divisions to identify and implement roadway improvements, traffic improvements, maintenance activities, or other countermeasures which can address the collision patterns.
Actions
- Identify collision concentrations annually, analyze the Top 5 Percent, and identify and implement roadway improvements, traffic improvements, maintenance activities, or other countermeasures which can address the collision patterns.
- Strengthen highway safety improvement program planning to improve readiness for grant programs to implement identified safety improvements and countermeasures.
