Systems and methods for dictating motion for bi-directional vehicles is provided. The method includes obtaining passenger and map data. The passenger data identifies an orientation of a passenger and the map data identifies route attributes for one or more route segments. The method includes determining one or more motion constraints for a bi-directional vehicle and map constraints for a routing the bi-directional vehicle based on the passenger data and the map data. The motion constraints can identify a vehicle orientation with which the bi-directional vehicle can travel. The map constraints can identify one or more route segments restricted from travel by the bi-directional vehicle. The method includes generating a constrained route based on the motion and map constraint(s). The constrained route can include permitted route segments and movements for the bi-directional vehicle. The method can include initiating the motion of the bi-directional vehicle based on the constrained route.
