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!

Introducing Our New Student Professional Worker – Lauren Ballard

After only my first five minutes as a Student Professional Worker (SPW) in LADOT’s Active Transportation Division, it was clear that 2017 is Vision Zero LA’s year of action. Mayor Garcetti declared Los Angeles a Vision Zero city in August 2015, and, since then, the department has assembled a Vision Zero team that has meticulously studied, planned, and prepared for this moment, releasing in January the Vision Zero Action Plan, announcing partnerships for community-based education campaigns in February, and presently designing projects to put into the ground later this year.

As an SPW, my primary role will be supporting the Vision Zero outreach and education campaigns. My first week here has been spent diving into a Coro Fellows Report on best practices Vision Zero literature and getting acquainted with campaigns carried out by other Vision Zero cities. Among the many not-so-fun facts I learned: males aged 18-54 are over five times more likely than females to be the at-fault party in collisions causing death or serious injury (“KSI” collisions); unsafe speed and inattention are two of the top factors in KSI collisions; KSI collisions are concentrated in Central Los Angeles, including DTLA, South LA, Westlake, and Pico Union; and these areas of concentration also score high on the Community Health and Equity Index. Utilizing this data, best practices literature, and interviews with local stakeholders, the report develops three core messages specific to Vision Zero LA: 1) public streets are community space; 2) you are responsible for others’ safety; and 3) transportation is about moving people (not just cars).

With that in mind, I shifted my focus to the community-based outreach and education campaigns currently in development. After reading through creative and diverse draft outreach plans, I’m really excited to work with these community groups to fine tune their outreach plans, get the word out about Vision Zero, start changing  behaviors and perceptions surrounding traffic safety, and work together toward the goal of zero traffic deaths by 2025.

P.S.  If you are interested in how other cities around the world promote Vision Zero,  I found a sample of clever, effective ads addressing dangerous driving behavior including an anti-drinking and driving ad out of New Zealand and an Australian ad addressing reckless driving and posturing called “the pinkie campaign.” I highly recommend giving both a watch.
