int DtRoadSegment::DtTmpGeometry::myEntryInsideLaneNum

The inside lane that connects, ie generates the radius constraint.

double DtRoadSegment::DtTmpGeometry::myEntryLaneIntersectSetback

The offset (along the lane) from the start of the segment (straight part) that the inside lane intersects its downstream lane.

double DtRoadSegment::DtTmpGeometry::myDesiredEntryCurveSpace

Distance from lane intersection to the end of the curve of desired radius.

double DtRoadSegment::DtTmpGeometry::myMinEntryCurveSpace

Distance from lane intersection to the end of a curve of min radius.

double DtRoadSegment::DtTmpGeometry::myDesiredLeftEdgeEntryRadius

Desired R for the segment left edge.

R for the inside lane is computed from this by adding/subtracting the lane widths:

int DtRoadSegment::DtTmpGeometry::myExitInsideLaneNum

Ditto for exit curve.

Note that offset (or setback) is positive along the positive segment X coordinate, so negative when the point in question is before the end of the segment.
