Office of Traffic Safety Issues LB Report Card

The California State Office of Traffic Safety compiles traffic safety statistics for cities state-wide and ranks cities according to the number of injuries and fatalities caused by vehicle collisions. Cities are ranked from safest to most dangerous by comparing the number of traffic collision injuries and fatalities recorded in each city. 

The rankings are adjusted by the number of miles driven and by the resident population of each city. (The rankings are not adjusted for the number of vehicles occupying the city). The rankings are organized for different transport categories like walking, cycling, motorcycling, driving and by the influence conditions that cause the collision like speeding, alcohol, visibility, and hit-and-run. 

Each city is ranked in each transport category from safest to most dangerous.  The charts following are a visual interpretation of the OTS data showing the level of danger for four beach cities from the latest OTS data available. The charts were compiled for pedestrians, bicyclists, motorcyclists and by the influence of speeding on traffic injuries and fatalities.

Laguna Beach consistently ranks over the 90th percentile for the most dangerous city in these categories among the four beach cities (it doesn't get better for alcohol, hit-and-run, DUI as influence factors). In the years to come a comparison will show if this trend persists.  -LS
