11.9 Working Corridor
Description A working corridor defines the valid offset range left and right of the centre line. When
working with irregular alignments such as traffic islands and parking lots working corridors
are useful to avoid displaying results from the wrong centre line element.
The example below shows the result you would get if working without defined working
corridor. For the measured position (b) RoadRunner finds the centre line point (c) with the
minimum perpendicular offset (f).
With a defined working corridor (e) RoadRunner would display with a message telling you
that the measured position is outside of the defined centre line.
a) Centre line
b) Measured position
c) Projected point on the centre line
d) Defined offset range for the working corridor
e) Working corridor
f) Offset from the centre line if no working corridor is used
