Introduction of Geocoding Collisions in California and Its Possible Application in Korea

抄録

Collision geocoding is a process of finding exact accident locations from other geographic data such as street address, zip codes, and postmile in traffic collision records. Through this process, the geocoded accident locations can be mapped onto digital maps based on Geographic Information Systems (GIS), and the results can be used for various purposes like displaying informative collision maps and conducting spatial analyses. Recently, in California, there was an effort to geocode collision data obtained from the Statewide Integrated Traffic Records System (SWITRS) and the overall match rate was 91%. The availability of geocoded collision data will be beneficial to clinicians, researchers, policymakers, and practitioners in the fields of traffic safety and public health. Therefore, in this paper, we will introduce the geocoding method and explore how to apply it to Korean situation by comparing road and address systems of Korea with those of the U.S.
