Vision Zero Los Angeles at TRB

Vision Zero Lab members Jacqui Swartz and Tim Black recently attended the 2017 Annual Meeting of the Transportation Research Board to present some of our work on Vision Zero in the City of Los Angeles and get a snapshot of other important transportation work happening throughout the country.

Our Posters

We had two posters showcasing some of the work we have been doing at LADOT in support of Vision Zero, the campaign to reduce the number of traffic deaths. The first poster gives an overview of the corridor prioritization process. ( paper / poster)

The second poster reflected work that was done to improve the process for deploying conventional safety engineering measures. Within the overall Vision Zero engineering framework, this project would perhaps best be categorized as ‘doing what we already do, but better.’ ( paper / poster )

When not presenting, we spent the rest of the time checking out other interesting research / projects occurring throughout the country (and world). Here is a roundup of our favorites:

Other Posters

Left-Turn Pedestrian and Bicycle Crash Study: NYCDOT gave a poster presentation on the left-turn study that was already released earlier this year as a pdf presentation. Even though we were already familiar with the work, this was still one of the best looking posters and one of the more relevant posters pertaining to our work in LA. ( paper / poster )

Netherlands High-Speed Corridor Intersection Treatments: The presenter showed off what was being done in the Netherlands right now along high-speed arterials: a combination of (1) speed limit reductions at intersections and (2) slightly raised intersections to support the speed reduction. Rather than allowing cars to barrel down these roads once they get the green wave, this combination of engineering and policy forces them to slow down at the approach of each intersection. I was most interested in the idea of a lowered speed limit at intersections, but this probably requires a legislative amendment at the state level to enact. ( paper / poster )

Improvements to Statewide Collision Reporting to Understand Sidewalk-Related Bicycle Collisions: This was a very simple survey that looked at which state crash forms allowed for the researcher to be able to tell whether a bicycle rider was on the sidewalk or not. ( paper / poster )

Improvement of Crash Data Collection, Processing and Analysis by a Web-Based Software: This poster presented a complete process for collecting, storing, and analyzing crash data. In California, with the SWITRS format, we’ve mostly figured out the right structure for storing the data. Hopefully we, along with other cities, can improve the data collection process (still using paper, yikes!) and the Vision Zero work in Los Angeles is already focused on the third part, analyzing data. We’ve spent a lot of time thinking about these topics, but this paper would be useful to anyone who is still trying to wrap his/her head around collision data. ( paper / poster )


Vision Zero in US Cities: The General Managers from the Departments of Transportation in New York, Los Angeles, and San Francisco made up a panel discussion on the progress of Vision Zero in U.S. cities. They specifically discussed the challenges of moving from planning to action, and we (Los Angeles) shared some of the innovative ways we are connecting to the public through art with our Creative Catalyst Artist in Residence.

Enhancing Efficiency Through Information-Sharing Tools in a Public-Sector Environment: This was a great way to learn about what other agencies are doing to coordinate work and efficiencies through the use of data and data-driven information.

Transportation and Public Health: Effects that transportation can have on public health by reducing transportation related casualties, providing easy access to healthcare services, mitigating environmental impacts, and reducing the transmission of communicable diseases. Partnership between ODOT & OHA developed to model and identify was is being done in active transportation to improve health and start to show the value of those benefits.
