the first guidance bogie is selectively returned into the first position or

the second guidance bogie is selectively returned into the third position.

13. The vehicle guidance system according to claim 1 , wherein the first guidance bogie is arranged laterally to a port side of the vehicle and the second guidance bogie is arranged laterally to a starboard side of the vehicle, and the guidance bogies are operable independently from each other.

14. The vehicle guidance system according to claim 13 , wherein a first guidance track is arranged on a port side of the guideway and a second guidance track is arranged on a starboard side of the guideway, and

wherein the common crossing comprises a port path and starboard path, over one of which the vehicle selectively travels.

15. The vehicle guidance system according to claim 14 , wherein, to selectively travel over the port path, the second guidance bogie is positioned in the fourth position, and

wherein, to selectively travel over the starboard path, the first guidance bogie is positioned into the second position.

16. The vehicle guidance system according to claim 13 , wherein additional guidance bogies are arranged on the port side of the vehicle and additional guidance bogies are arranged on the starboard side of the vehicle,

wherein the guidance bogies on the port side of the vehicle are operable together and the guidance bogies on the starboard side of the vehicle are operable together, and the guidance bogies on the port side of the vehicle are operable independently of the guidance bogies on the starboard side of the vehicle.

17. The vehicle guidance system according to claim 1 , wherein the vehicle comprises an exoskeleton frame surrounding a pod.

18. The vehicle guidance system according to claim 17 , wherein the pod is free to rotate along the vehicle's longitudinal axis within the exoskeleton.

19. The vehicle guidance system according to claim 18 , wherein, when the vehicle turns, the pod rotates along the vehicle's longitudinal axis relative to the exoskeleton.

20. The vehicle guidance system according to claim 1 , wherein, when the first guidance bogie is selectively positioned into the second position, the second guidance bogie remains in the third position for travel, and

when the second guidance bogie is selectively positioned into the fourth position, the first guidance bogie remains in the first position for travel.

21. A process of guiding a vehicle approaching a common crossing with the vehicle guidance system according to claim 1 , the process comprising:

one of:
