02 / Full sequence overview (broken axis — NOT to scale)
The intervals shown are real engineering station differences; each visual segment uses equal schematic space.
03 / Continuous-scale detail canvas
Pan by dragging empty roadway; drag orange warning-sign diamonds to simulate an obstruction. Mouse wheel or slider zooms the measured station axis. Green = suggested buffer, red = work zone.
Continuous scale in drawing: 1 ft = 1 px at 1× zoom. Transverse lane widths are illustrative, not scaled to longitudinal distances.
04 / Stationing & calculation export
Primary taper—feet
Max taper spacing—ft / channelizer
Taper devices—both endpoints included
Suggested buffer—Table 6B-2
This preview does not account for traffic volumes, sight distances, engineering judgment, taper-type applicability, TA selection, flaggers, pedestrians, lane-closure legality, or local supplements.
