wtp_postitive - use this as filler for ends or as a template to add to your model (adjust height to 2.84 mm)
wtp_negative - use this as a template to subtract from your model.
wtp_staright1 - straight piece length 1
wtp_staright1_lego- straight piece length 1 with Lego System compatible studs
wtp_straight2 - straight piece length 1
wtp_curve - curved piece
Height is 2.84 - 0.2 mm first layer + 0.24 layer height. Measured height of original pieces is about 2.8-2.9. Width is 110 mm.
Curved piece is not 45 degrees, but 43.9 as is original. So mix them with original flexible pieces.
Lego staright piece is 14x14 but edges are smaller than a real Lego baseplate, so they do no stack as a one big plate in Lego terms. So use them separately or create your own custom pieces.
WayToPlay is a great flexible set of road pieces.
