curvature point

arbitrary points on the curved road that has associated location and value of curvature

curve end point

location where the radius of curvature of the curved roadway ahead becomes ≥RC

location where the radius of curvature of the curved roadway ahead becomes ≥RC

curve start point

location where the radius of curvature of the curved roadway ahead becomes less than RC

location where the radius of curvature of the curved roadway ahead becomes less than RC

curved road

section where the radius of curvature is less than or equal to RC
NOTE 1 to entry: RC denotes the maximum radius of curvature to be regarded as a curvature point of interest for potential warning for CSWS.

At

illuminated surface

incidental visible road feature

visible patterns on the road surface that were not explicitly intended to delineate the boundaries of the lane, but which are indicative of the position of the lane
NOTE 1 to entry: These can include such features as pavement seams or edges and curbs.

lane boundary

borderline of the lane that is determined by a visible lane marking; and in the absence of a visible lane marking, by incidental visible road features or other means such as GPS, magnetic nails, etc
NOTE 1 to entry: In the case of a visible lane marking, the boundary is at the center thereof.

lane; traffic lane

portion of carriageway designed to accommodate a single line of moving road vehicles
NOTE 1 to entry: The term “lane” is often used to refer to a “traffic lane” when the context is known to be “traffic”.
NOTE 2 to entry: A traffic lane can be bi-directional, such as a single lane road, a two-way turn/overtaking lane, or a reversible flow lane.
NOTE 3 to entry: Some jurisdictions allow…
