Regional High Injury Network
High injury networks (HINs) include stretches of roadways where the highest concentrations of collisions occur on the transportation network. The HIN is intended to show where fatal and serious collisions are occurring in the region. The HIN, however, is not an assessment of whether a street or location is dangerous. Rather, the 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:
-
Determining geographic areas where crashes are concentrated, and the causes of these crashes, so that efforts can be focused on the most challenging areas and crash factors.
-
Strengthening collaboration to focus street improvements and education campaigns (e.g., Go Human) along the HIN.
-
Prioritizing investments within these areas to reduce collisions.
Get Involved
Transportation Safety Working Group
The Transportation Safety Working Group functions as a forum for SCAG staff to engage transportation safety stakeholders in the development and implementation of plans and policies to reduce transportation-related 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 aguirre@scag.ca.gov or (213) 236-1990.
Go Human
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.
