Identification and analysis of high crash locations typically use many years of historic crash data that require association of crashes to the roadway segments and intersections. This association present a challenge given the roadway data change over time. Crash geocoding on a versioned roadway base map presents some unique migration challenges, such as what to do when a segment is split or merged, roadway geometry changes, or intersections are added or removed. This presentation shares some of the challenges involved in migrating a large volume of incident data from one baseline map to another in a timely manner, possible solutions to avoid repetitive human intervention, and lessons learned from having gone through the process.
