The Landmark Kilometre Inventory (LKI) is one of the Ministry of Transportation and Infrastructure's systems for identifying locations on the Provincial Highway network. It has been in use since before 1978.
LKI location codes are used by police to record and report crashes which occur on Provincial Highways. The Ministry's Collision Information System (CIS) is built upon the LKI. The RCMP and others use the LKI as the basis for locating landmarks along BC highways.
How the LKI Works
The LKI divides the highway network into segments. Each segment has a 4-digit identifier, and a designated start and end point. A segment may consist of one or both sides (directions) of a highway. Landmarks such as intersections and bridges along each segment are listed, along with the measured distance from the start of the segment, and a landmark type code.
See the LKI Revision History (PDF) for details of the changes in each release. (As of version 201312 this information is no longer included in each PDF LKI report.)
