A list of the 20 Los Angeles city streets, and several dozen more intersections, hardest hit by traffic-related deaths and injuries, and where transportation officials hope to focus most of their safety improvement efforts, was released this month.

Upcoming traffic-safety upgrades will be focused in these hot spots as part of an effort to meet Los Angeles’ Vision Zero goal of eliminating traffic-related fatalities by 2025.

The department picked out these streets and corridors as the “worst of the worst” from a larger pool of streets known as the “high-injury network,” which makes up 6 percent or more than 450 miles of total LA streets, transportation engineer Daniel Samaro told a Los Angeles City Council committee Wednesday.

These are where the transportation department plans to “put our focus” for installing traffic safety improvements, he said. The quickest projects include striping and signage, while more involved projects include signals, he said, while the most intensive projects include those that require pouring concrete and changing the structure of the streets.

The list adds another 20 streets, and 60 intersections, to an existing batch of streets identified in 2017 that are now already getting safety-related improvements.

Three streets in the San Fernando Valley:

Ventura Boulevard, between Garden Grove and White Oak Avenue;

Victory Boulevard, between Fulton Avenue and Whitsett Avenue; and

Woodman Avenue, between Sherman Way and Saticoy Street.

Two of the streets were in the Harbor area, or Council District 15:

Normandie Avenue, between Lomita Boulevard and Pacific Coast Freeway; and

Gaffey Street, between 14th Street and O’Farrell Street.

About a third of the 60 total intersections were in the San Fernando Valley and seven were in the Harbor area. A full list of the intersections can be found here.

The rankings are based on a formula that factors in the number of traffic-related deaths and serious injuries that have occurred on the streets and intersections over the last five years, between 2013 and 2017.

Transportation officials noted that out of the top 20 streets ranked as having the highest number deaths and injuries, half are in communities considered to be the most burdened by pollution, crime, economic and social hardships, and other challenges.

Through ranking the streets, transportation officials also looked into how the collision occurred, and found that a number of crashes involving cars making left turns happened at intersections with unprotected left turns.

There were some tweaks to the ranking system this time around, transportation said. The previous list puts extra weight on the most socio-economically burdened spots, and as well as deaths and injuries of pedestrian, bicyclist, senior and children.

But the new list does not put any additional emphasis on any particular group, and merely looks at the number of deaths and serious injuries that occurred, whether or not they were of motorists, pedestrians or cyclists, and without regard to their age or neighborhood.
