plus sign notation. If station 0+00
(0+000) is at the beginning of the
baseline, then station 13+50 (1+350)
would be 1,350 feet (meters) away from
the beginning but along the path of the
baseline.
Offset Offset is the perpendicular
distance from the baseline to a given
point. The locations of objects in
reference to the baseline are often
expressed using a station and offset.
Tangents (Baseline Segments)
Tangents are the straight-line portions of
a baseline.
Tangent (Geometric Condition) A
tangent (geometric condition) is the kind
of tangent you learned about in high
school.
• It means touching or passing through
at a single point.
• In the case of a line and arc, it means
perpendicular to a line drawn from the
intersection point to the center point
of the arc.
• In the case of two arcs, it means
intersecting in such a way that a line
drawn from the center point of one arc
to the center point of the other arc
passes through the intersection point.
