13. A transportation system for a vehicle having an upper support structure with a plurality of upper wheels capable of riding on the lower track and a lower support structure with a plurality of lower wheels capable of riding on the upper track, the wheels having a pair of outer sides and an inner area, the transportation system comprising:
a support structure;
a first lower track having a pair of lower rails, the lower rails supported the support structure;
a first upper track having a pair of upper ails, the upper rails spaced above the lower rails, the upper rails supported by the support structure;
a second lower track having a pair of lower rails, the lower rails supported by the support structure, the lower rails of the second lower track intersect the first lower track by the crossing of rails and defining a transition section including a concave auxiliary track portion having a pair of support grooves and defining an area cut out of the rails adapted for the wheel of the vehicle moving from being supported by the tracks over the inner area of the wheel to support of the outer sides of the wheel by the pair of support grooves over a distance cut in the track therein allowing for the crossing of the first lower track; and
a second upper track having a pair of upper rails, the upper rails spaced above the lower rails, the upper rails supported by the support structure, the upper rails of the second upper track intersect the first upper track by the crossing of rails and defining a transition section including a concave auxiliary track portion having a pair of support grooves and defining an area cut out of the rails adapted for the wheel of the vehicle moving from being supported by the tracks over the inner area of the wheel to support of the outer sides of the wheel by a transition section wherein the wheel of the vehicle moves from being supported by the tracks over the inner wheel area to support of the outer sides of the wheel area by the pair of support grooves over a distance cut in the track therein allowing for the crossing of the first upper track.
