rightLanes - double; number of lanes right from the link design line

laneWidth - Length; lane width

laneType - LaneType; lane type

speedLimit - Speed; speed limit

Returns:

setOffsetEnd

public LaneFactory setOffsetEnd(Length endOffset)

addLanes

public LaneFactory addLanes(Stripe.Permeable... permeable)

Adds a lane pair for each permeable, where the permeable determines the right-hand side line when building from left to right and vice versa. The left-most line is created in leftToRight(), meaning that each permeable describes permeablility between a lane and it's right-hand neighbor, when building left to right (and vice versa).

Returns:

this LaneFactory this lane factory for method chaining

addShoulder

Adds 1 or 2 shoulders to the current set of lanes.

Parameters:

width - Length; width of the shoulder

lat - LateralDirectionality; side of shoulder, use null or NONE for both

Returns:
