These are very useful fields for ranking by intersections. RoadSafe GIS utilizes these fields for generating rankings by various safety performance functions.Party and victim data tables that correspond to the SWITRS collision file.Note that the field names have been updated to reflect the original headers provided by CHP in addition to our several added fields.
