LADOT announces update to Vision Zero High Injury Network

This month, LADOT updated the Vision Zero High Injury Network (HIN), the network of city streets where we can make the biggest difference in our efforts to save lives. The update can be found on the City’s Geo Hub, our public platform for exploring and visualizing location-based open data.

The first iteration of the HIN launched in 2016 and was based on collision data available from 2009-2013. Though only 6% of Los Angeles’ street miles are on the HIN, we found that nearly seventy percent of all deaths and severe injuries of people walking occurred on this network. The HIN helps us focus our safety efforts, maximize resources and save lives.

Vision Zero’s 2017 Action Plan called for an update of the City’s High-Injury Network using new collision data made available by the Statewide Integrated Traffic Records System (SWITRS). As a first step, we mapped fatalities and serious injury collisions (KSIs) involving people walking and bicycling using the most recent data (2012-2016). With this new data set, we found that the corridors with a high density of KSIs from 2012-2016 were nearly the same as the HIN corridors identified previously. This information will be used to identify a new round of priority corridors for safety improvements.

Many of the Vision Zero improvements on the High Injury Network began installation in May 2017 and safety data over that time has not yet been included in our High Injury Network analysis (SWITRS data from 2017 and 2018). Where we’ve made Vision Zero improvements and have available safety data, like the Hollywood and Highland intersections, we’ve seen positive results. See attn. Media’s coverage of the scramble here. As new data becomes available and incorporated, we hope to see fatalities decline and remove streets from the HIN.

Changes to the HIN

Our HIN updates can be categorized into the following types:

  • Additions: We identified three new streets (6th St, Glenoaks Blvd, and Glendale Blvd) that witnessed a high number of KSI collisions between 2012 and 2016 yet were not part of the original HIN. Seventeen KSI collisions involving a pedestrian or a bicyclist occurred on just 2.8 miles of these streets in the last 5 years.
  • Extensions: We also saw that a high number of bicycle and pedestrian collisions occurred at the edges of the existing HIN. To capture these new hotspots of collision activity, we have extended 13 of the existing HIN corridors.
  • Connections: We identified two streets (Vanowen St and Central Ave) where we connected existing HIN corridors based on the newer collision data.

High Injury Network Changes

 

Street To/From HIN Modification Miles Bicycle and Pedestrian  KSI Collisions KSIs per Mile
6th St. Ogden Dr./Cochran Ave. New Corridor 0.7 6 8.6
Glenoaks Blvd. Peoria St./Roscoe Blvd. New Corridor 1.6 7 4.4
Glendale Blvd. Revere Ave./Glenhurst St. New Corridor 0.5 4 8.0
48th St. Crenshaw Blvd./Western Ave. Extension 1.2 6 5.0
Vanowen St. Woodman Ave./Ethel Ave. Connection 0.8 3 3.8
Vanowen St. Hatillo Ave./De Soto Ave. Extension 1.2 5 4.2
Nordhoff St. Haskell Ave./Reseda Blvd Extension 1.8 7 3.9
Riverside Dr. Laurelgrove Ave. /Van Nuys Blvd. Extension 2.7 6 2.2
Ventura Blvd. Topanga Canyon/Fallbrook Ave. Extension 0.9 4 4.4
Normandie Ave. Melrose Ave./Beverly Blvd. Extension 0.5 5 10.0
Beverly Blvd. Bonnie Brae St./Rampart Blvd. Extension 0.5 5 10.0
Olympic Blvd. Crenshaw Blvd./La Brea Ave. Extension 1.3 6 4.6
Washington Blvd. La Brea Ave./Redondo Blvd. Extension 0.3 4 13.3
Vermont Ave. 88th St./120th St. Extension 2.4 9 3.8
Central Ave. Slauson Blvd./Manchester Ave. Connection 2.1 10 4.8
Cesar E Chavez Ave Keller St./ Vignes St Extension 0.3 5 16.7
Total: 18.8 92 4.9

 

In total, these additions to the HIN cover 19 miles, but account for over 90 bicycle and pedestrian KSI collisions in the last 5 years. After making these modifications to the network, the share of bicycle and pedestrian KSIs on the HIN remains at roughly two-thirds (64 percent).

This updated HIN is available on the City’s GeoHub. We will also be publishing the updated collision data to the GeoHub as well, so stay tuned!

Vision Zero featured on LA GeoHub Launch

Mayor Eric Garcetti and Esri President Jack Dangermond today unveiled the City of Los Angeles’ new GeoHub — one of the nation’s most complete collections of urban map data. The GeoHub builds on Mayor Garcetti’s third Executive Directive, which created L.A.’s first open data portal. By making more than 500 types of map data available to residents, city workers, and private industry, the GeoHub helps Angelenos better understand their communities, and City departments better coordinate construction, road paving, and public safety efforts.

The Los Angeles GeoHub was created in collaboration with Esri, the world’s leader in geographic information systems (GIS) technology. Built on Esri’s ArcGIS platform, GeoHub pools map data layers from more than 20 different departments — allowing users to create living maps and build custom applications to solve pressing challenges and optimize city services.

For Vision Zero Los Angeles, we created a featured Story Map, showcased on the GeoHub, that displays some key datasets that inform the Vision Zero approach. We know that, on average, every year more than 200 Angelenos lose their lives while traveling on city streets. The Vision Zero philosophy holds that these deaths are both unacceptable and preventable, and takes a data-driven approach to reducing severe and fatal injuries.  With this Story Map, we demonstrate that people walking and bicycling in Los Angeles are over-represented among traffic deaths. Also, communities with the most need are also areas where there are high density of fatalities and severe injuries among people walking and biking.

Vision Zero App for LA GeoHub displaying data on fatal and severe injuries

 

The L.A. GeoHub is an important pillar in Mayor Garcetti’s broader strategy of using technology and data to delivery transparency, efficiency, and community engagement. For Vision Zero Los Angeles, we look to the GeoHub as an important tool to share and build comprehensive transportation and health databases for goals of Vision Zero- outlined in our Executive Directive #10.

 

Los Angeles Recognized as Vision Zero Leader

Today, Los Angeles was selected as one of 10 leading cities to participate in a new national program to advance Vision Zero, the goal of eliminating traffic fatalities and severe injuries among all road users. Mayor Eric Garcetti launched the Vision Zero Los Angeles initiative on August 24, 2015 by signing Executive Directive #10, declaring safety to be the number one priority in designing and building our streets and sidewalks.

This new Vision Zero Focus Cities program was launched today by the Vision Zero Network, a national collaborative campaign aimed at advancing this shift towards safety, health, and equitable mobility for all. In addition to Los Angeles, other cities included in this program will be: Austin, TX; Washington, DC; New York City, NY; Boston, MA; Chicago, IL; Fort Lauderdale, FL; Seattle, WA; Portland, OR; and San Francisco, CA.

“Los Angeles is proud to join the Vision Zero Focus Cities program,” said Seleta Reynolds, General Manager of the Los Angeles Department of Transportation and President of the National Association of City Transportation Officials (NACTO). “Our shared goals to stop traffic deaths are ambitious and urgent.  We will get there faster together by learning from one another.”

The 10 cities were chosen based on their positions as – or expectations to become – national leaders in Vision Zero. Additionally, they were required to demonstrate a commitment to work collaboratively with their peers to improve upon their traffic safety efforts and serve as models for other cities.

“We recognize Los Angeles’ leadership in being an early-adopter of Vision Zero and dedicating its staff and resources toward prioritizing safety for all who are walking, bicycling and driving,” said Shahum. “We know that Los Angeles is serious in its commitment to reach zero traffic fatalities and severe injuries, and we commend their willingness to partner with peers in other Vision Zero cities to make greater progress not only locally but across the nation in safe streets for all.”

Lead participants in the Focus Cities program will include representatives of each city’s Mayor’s Office, Transportation Department, Police Department, and Public Health Department. In addition, there will be a concurrent track for collaboration among leading Vision Zero community advocates from each of the Focus Cities.

“Los Angeles Walks applauds the Vision Zero Network for launching the Focus Cities Program, and comments the City of Los Angeles for its inclusion,” said Deborah Murphy, founder and Executive Director of Los Angeles Walks, a pedestrian advocacy organization. “Every year in Los Angeles, over 200 people are killed on city streets – almost half of them while walking and biking. There is no time to spare when it comes to implementing better street design, targeted education, and strategic enforcement that creates safe, equitable walking environments and saves lives.”
