High injury network
Street network based safety analysis / From Wikipedia, the free encyclopedia
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] and Canada[5][6] as part of their efforts to work toward Vision Zero.[7] 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.[8]
Creating a HIN is a data-driven[9] exercise, and the analytic methods and data sources used may vary widely.[10][11] 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.[11]
