Landmark Kilometre Inventory
The Landmark Kilometre Inventory (LKI) is one of the systems used 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 that occur on provincial highways. The Collision Information System (CIS) is based upon the LKI. The RCMP and others use the LKI for locating landmarks along B.C. highways.
How the LKI Works
The LKI divides the highway network into segments. Each segment has a four-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. The Excel and database versions of the LKI also include highway classification and landmark geographic location data.
The LKI is revised on an ongoing basis, and new versions are published usually once a year.
When a segment is revised, it is given a new segment number if the Km of any its landmarks has changed. This makes it clear that a Segment-Km location code with an old segment number refers to the old LKI version. Transformation data is maintained so that location codes can be transformed between LKI versions. The Collision Information System, for example, uses the transformation data to maintain all its collision locations in a single version of the LKI.
B.C. LKI - July 2019 Version
B.C. LKI - July 2018 Version
B.C. LKI - July 2017 Version (201707b)
(Update published 20-Apr-2018)
This version has all the same Segments and Landmarks as the 201707 version, but has many intersection landmark type updates. All signalized intersections now have landmark type A3 or A5. Many A1s were changed to G6, Y8, etc. File LMtype_Count_Changes_to_201707b.xlsx shows the number of changes by landmark type.
See the LKI Revision History (PDF) for details of the changes in each release.
