Geocoding Police Collision Report Data From California: a Comprehensive Approach

By (Reprint)

How could creating a database of crash locations be difficult? In California police reports are written with relative positions - based on mile markers or intersections. In addition, the data had to be pre-processed and cleaned, an offset tool needed to be built, and statewide mile marker database developed. The outcome? An overall match rate of 91% and a clean database to serve "clinicians, researchers, policymakers, and practitioners in the fields of traffic safety and public health." Read up on what a broad-based international team learned in its research in this article published in the International Journal of Health Geographics.
