THE HIGH-INJURY NETWORK
Los Angeles is a very big city . Despite this , our initial analysis revealed that only a small percentage of our streets account for a large percentage of people killed and severely injured in traffic collisions . Just 6 percent of our streets , which we have designated as the High-Injury Network ( HIN ), make up nearly two-thirds of all KSIs involving people walking . This network is mostly made up of arterial streets : wide , signalized streets that carry high volumes of traffic and transit ridership , but also serve as commercial corridors where many people run errands or enjoy nightlife on foot . This combination of fast-moving vehicles with many vulnerable people makes collisions not only more frequent but also more deadly — pedestrian KSI collisions on arterial streets in Los Angeles are seven times more deadly compared with collisions on non-arterial streets .
By focusing our efforts on the HIN , we can make the biggest effect in reducing death and severe injury . And , as we make these improvements , we will continue to update the HIN so that it remains a relevant guiding resource .

Nearly three times as many collisions occur at intersections than at mid-block locations .

PRIORITY CORRIDORS
The vast majority ( 70 percent ) of KSI collisions occur at intersections rather than mid-block locations . These intersection-based collisions tend to be along high-collision corridors rather than focused at a few locations , suggesting that corridor-level treatments , especially those targeted at reducing speeding , are likely to be more effective at eliminating fatalities compared with spot-level treatments scattered throughout the City .
Based on this finding , we have identified 39 high-priority corridors within the HIN to begin our work ; these are detailed in our Vision Zero Action Plan . If we are successful at eliminating bicycle and pedestrian KSIs along these corridors , we will be on track to meet our first Vision Zero goal : a 20-percent reduction in traffic deaths by 2017 compared with 2016 .
