• Data analysis of serious crash patterns, factors

• Recommend strategies to address the patterns found

• Safety Workgroup provided guidance, peer review

• States that drive more see more fatalities

State-by-State

4

• Surface streets with more congestion have lower serious crash rates

• Likely due to speed

Safety and Congestion

5

• Wider roads are disproportionately represented

Number of Lanes

6

• Increased VMT more exposure more crashes• Uncongested conditions speed less safe• Wider roads less safe

Some factors that Influence Safety(all else being equal)
