They engage in educational programs like the San Ramon Valley Street Smarts and CHP Start Smart to promote traffic law adherence. The Traffic Unit collaborates on traffic calming measures with town engineers, such as lane striping and stop sign installations, aiming to reduce accidents and enhance road safety. The Traffic Unit enforces laws via citations and patrol officers support this mission by monitoring high -collision areas and targeting drivers violating key traffic laws within their designated zones.

DANVILLE CALIFORNIA Accident Rate per MVM Definition: Number of accidents per million vehicle miles traveled (MVM). • Formula: • Accident Rate = (Number of Accidents x 1,000,000) _ Total Vehicle Miles Traveled • Purpose: Measures road safety, accounting for traffic volume. 1 1 DANVILLE CALIFORNIA Importance to Transportation Engineers • Role: Guides road design and speed limit decisions. • 85th Percentile: Aligns speed limits with driver behavior, reducing variability. • Accident Rate: Identifies high-risk areas for improvements (e.g., signage, traffic calming). DANVILLE CALIFORNIA Why It Matters • Big Picture: Links driver behavior (85th percentile) to safety (accident rate). • Impact: Enhances road safety and efficiency through data -driven decisions.
