High injury networks (HINs) include stretches of roadways where the highest concentrations of collisions occur on the transportation network. An HIN is intended to show where fatal and serious collisions are occurring in the region. An HIN, however, is not an assessment of whether a street or location is dangerous. Rather, an HIN suggests which corridors within a transportation network carry a higher risk of injury. When developing an HIN, jurisdictions typically want to identify a subset of the network where the most collisions are occurring (>50%). Developing an HIN can prove helpful for a variety of reasons, including:
- Identifying areas of need;
- Providing agency staff with more information on where they can focus limited resources;
- Providing opportunities to understand how communities of concern or disadvantaged communities are impacted by higher rates of collision and serious injury; and
- Assisting with building greater public and political support.
In 2018 SCAG developed its first regional HIN. In developing the HIN, SCAG reviewed HIN methodologies for a variety of jurisdictions including Los Angeles, San Francisco, Portland, and Portland Metro. SCAG borrowed elements from their approaches to develop one that could work for the entire region. To learn more about SCAG’s regional High Injury Network, click here.
Transportation Safety Working Group
The Transportation Safety Working Group functions as a forum for SCAG staff to engage transportation safety stakeholders in discussions regarding plans, programs, projects, tools, resources, and best practices that support reducing fatalities and serious injuries. Meetings occur on a quarterly basis and are open to agency staff, elected officials, and the public. More information regarding specific meetings and other regional planning working groups can be reviewed online here.
Transportation Safety Program
SCAG is available to work with local jurisdictions on issues related to transportation safety. To learn more about our technical assistance opportunities, please contact Courtney Aguirre at email@example.com or (213) 236-1990.
Go Human is a community outreach and advertising campaign with the goals of reducing traffic collisions in Southern California and encouraging people to walk and bike more. SCAG hopes to create safer and healthier cities through education, advocacy, information sharing, and events that help residents re-envision their neighborhoods.
If you’re interested in getting involved, you can find more information on the campaign, make use of trainings and webinars, and request safety resources for your jurisdictions, such as the Go human Kit of Parts, and the Go Human Resilient Streets Toolkit.
There are a variety of transportation safety-related tools and data, some of which are highlighted and linked to below.
