A high injury network (sometimes shortened to HIN [1] ) is a way of identifying parts of an urban street network with higher rates of traffic injuries or fatalities, typically with a goal of prioritizing these streets for safety interventions. [2] High injury networks have been published by many cities in the US [3] [4] [5] and Canada [6] [7] as part of their efforts to work toward Vision Zero. [8] While data on fatalities and collisions have long been available in many municipalities, the first HIN per se was published by San Francisco in 2013, [2] though work on similar efforts had begun there as early as 2011. [9]
Creating a HIN is a data-driven [10] exercise, and the analytic methods and data sources used may vary widely. [11] [12] Most HINs are created at the scale of cities where detailed collision data is collected, though regional efforts at defining a more standardized approach also exist. [12]
