In Italian DATEX Profile we manage the temporary alternating one-way for vehicles using Networkmanagement class RoadOrCarriagewayOrLaneManagement with roadOrCarriagewayOrLaneManagementTypeassigned to IntermittentShortTermClosures.
besides the definition seems more tuned to specify closures then alternating one-way traffic.
No mention of "alternate one-way" road management can be found in the model
we then ask to mention this specific condition in the definition to grant all potential users to manage this situation record in the same way, because we had some implementers which had been using SingleLineAlternateTraffic which we assume related to traffic flow in the same direction, not to a reverse traffic flow condition as alternating one-way is.
otherwise consider to introduce a specific new item to RoadOrCarriagewayOrLaneManagementEnum to state this specific case.
