VISION ZERO SAFETY STUDY AND TECHNICAL ANALYSIS
We conducted a Safety Study in March 2016 to summarize what we learned from the analysis of our collision landscape . The study analyzed the most recent and available data of reported collisions ( 2009 – 13 ; as validated by the State of California ) to identify trends in terms of where , how , why , when , and to whom collisions are happening .
Who : Pedestrians , Bicyclists , and Motorcyclists
Fatal and severe collisions in Los Angeles disproportionately affect people who walk and ride bikes , as they are physically more exposed than people in vehicles . While people walking and bicycling are involved in 14 percent of all collisions in the City , they account for almost 50 percent of traffic deaths . Motorcycle riders are also at greater risk ; they are present in only 3 percent of collisions but account for 15 percent of all traffic deaths .
Who : Drivers
The majority of drivers in severe and fatal collisions involving vulnerable road users are men . However , hit-and-runs account for more than one out of five severe and fatal collisions involving pedestrians or bicyclists . Hit-andruns make it difficult to accurately track data about drivers involved in collisions .
How
Behaviors most associated with severe and fatal collisions in Los Angeles are speeding , insobriety , and failure to yield .
Why
Collisions occur on our streets for many reasons . Our collision analysis informed us where and why collisions occur . Through this analysis , we developed " collision profiles ," a group of collisions with similar contributing factors , that helped us identify physical design interventions ( countermeasures ) that would be most effective at addressing the collisions . For example , a solution for frequent left-turn conflicts at crossing signals might be a Leading Pedestrian Interval .
When
In Los Angeles , the highest number of all collisions take place between 3:00 p . m . and 6:00 p . m . However , serious and fatal collisions are highest between 6:00 p . m . and 9:00 p . m .
Where
Many fatal and serious collisions take place along major arteries and at the intersections of large two-way streets where drivers , pedestrians , and cyclists compete for space .
