The Landmark Kilometre Inventory spatial layer is used primarily by the Ministry of Transportation and Infrastructure (MOT) to represent routes against which accident data and traffic counts are collected. This method describes roads by a four number designation referred to as a segment (i.e. 0375) This spatial layer was created based on Digital Road Atlas (DRA) centerline using linear referencing

Surface Type describes the type of surface material used on road

The Road Features Inventory spatial layer shows all highways under the administration and control of BC MoT for which the Ministry has maintenance responsibility

Ministry of Transportation Regional Boundary is an exclusive geographic area within the province that the Ministry organizational unit is responsible for. Each Ministry Region is partitioned into one or more non-overlapping Ministry Districts that cover the entire Ministry Region

Highway Maintenance Class defines the level of service for maintenance of the highway, normally, a function of the traffic usage type and traffic volume. This layer contains polylines

A Guardrail is a barrier fastened to the end of a bridge abutment, along the shoulder of a road or between travel lanes of opposing traffic. It is a Linear feature

A Sign is a lettered board, message or other display which includes all regulatory, warning, guide, informational, advisory, construction and maintenance and route markers, but excluding electronically controlled messages/displays. It is a Point feature

A Highway Profile defines the number of through travel lanes, including passing and truck lanes, and whether the road is divided or not. It is a Linear feature

A Retaining Wall is a structure designed to protect the road infrastructure by retaining materials on the fill side to prevent road bed slips and by retaining materials on the cut side to prevent the road surface from being covered by debris. Retaining walls that are greater than or equal to 2m in height are stored in the MoT Bridge Structure Road dataset. It is a Linear feature

Highway Reference Point is a visibly recognizable feature used to describe and identify a point on the Highway (i.e., a reference point abstracted on the Highway and defined by a physical landmark such as an intersection). HRP Landmarks are used in order to provide reference points relating to inventory item data
