For more information on the attributes associated with collisions, please download the codebook.Collected SWITRS (Statewide Integrated Traffic Records System) Data from 2009 - 2013. Geocoded and prepared by RoadSafe GIS All collisions on non-state highways marked in SWITRS as occurring in LA City jurisdictionCollisions on state highways where all or a portion of the highway is a surface street:State highways 42, 213, 1, 27 (and the intersection of Ferry@Seaside and Navy@Seaside on SR 47)State highway 110 – All between postmile values 0 and .745State highway 170 – All between postmile values 9 and 10.61State highway 2– All postmile values below 14.08 (Glendale Fwy begins)Collisions at ramp intersections with local roads. In some cases it can be difficult to distinguish an intersection with a local road or another ramp segment. However, all the collisions with these ramp values are included: 1 – Ramp Exit, Last 50 Feet3 – Ramp Entry, First 50 Feet4 – Not State Highway, Ramp-related, Within 100 Feet5 – Intersection6 – Not State Highway, Intersection-related, Within 250 FeetAdditional fields in the collision data table for a standardized matching address (match_addr), primary road name (m_primaryr), secondary road name (m_secondrd). 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.
