Lane Constraint Start-End: Specify the starting and ending transverse station range along the roadway where you want to place the lanes.Suppose a roadway has a width of 48 feet, and the PGL location is assumed to be 0. The left width is 38 feet, and the right width is 10 feet when looking upstation from the alignment. In this case, the lane placement will occur within the range of -38 to 10 feet in the transverse direction. If there are restrictions on lane placement between 5 and 10 feet, as well as between -38 and -28 feet in the transverse direction, the lanes will only be placed between -28 and 5 feet in the transverse direction. Therefore, the user needs to enter the lane constraint start value as -28 and the lane constraint end value as 5.
