•  Date and Time (YYYYMMDDHHMM)

See Appendix F for data collection instructions. Midnight is defined as 00:00 to represent the beginning of a new day. YYYY must be entered. Absence of year should result in an edit check. In rare situations MMDDHHMM can be unknown.

•  Name of the County

Record the county or equivalent entity in which a crash occurred. If codes are used instead of name, use the GSA Geographic Locator Codes (GLC) that can be found on the Internet at: http://www.gsa.gov. See Appendix G. If state-assigned codes are used, they should be convertible to the GSA/FIPS format.

•  Name of the Political Jurisdiction

Record the name identifying the city/place in which the crash occurred. If codes are used instead of names, use the GSA Geographic Locator Codes (GLC) that can be found on the Internet at www.gsa.gov. See Appendix G. If state-assigned codes are used, they should be convertible to the GSA/FIPS format.

•  Latitude/Longitude Coordinates

The optimum definition of Crash Location is a route name and GPS (global positioning system)/GIS (geographic information system) locator, if a highway agency has a linear referencing system that can relate geographic coordinates to specific locations in road inventory, traffic, driver, and other files. The location information in a crash file must have the capability to be linked to location information in these other important files required to study site-specific safety issues. GPS/GIS provides the latitude/longitude coordinates indicating where the crash occurred.

•  Linear Referencing System (LRS)

An LRS can create complex overlays of multiple events or occurrences along a route to support corridor planning, pavement rehabilitation, or other complex analysis. An LRS permits users to share information maintained by different data providers across different data layers. An LRS is not created by the geographic information system (GIS), but is actually replicated to model what is in the field. All linear data (traffic volumes, pavement types, speed limit zones, etc.) and point data (crashes, signs, etc.) collection efforts need only specify the location or endpoint locations in terms of the LRS components.

•  Link Node System (not recommended)

Note: States with no system or a link node system should plan to develop or upgrade to a linear referencing system or one that documents latitude/longitude coordinates.
