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.
