Thank you for your reply, Kaduna.

Please, don't get me wrong, but that's not a good approach to change something as important as this.
In this set, you eliminated an existing and well mapped stretch of road and wrongly assumed a oneway direction based on an erroneous assumption. There are many reasons why a vehicle can take a certain direction in a road. Changing the map based on that doesn't seem correct. 
You even have the streetside photos on iD and JOSM editors, which you didn't bother to check.

The same happened with this changeset:

The reason is similar, but it's equally a bad approach.
If TomTom is going to change major roads based on its traffic, I think it is time for TomTom to reconsider this task.

Regards,
António.
