Schiphol and Air Traffic Control the Netherlands (LVNL) have applied standard practices for taxiing and towing on the Alfa and Bravo taxiways by introducing a one-way traffic system. The driving direction on the Alfa runway is now clockwise and the Bravo runway is anticlockwise. These standard routes will improve predictability of taxiing and towing movements, in order to reduce the likelihood of on-ground safety occurrences. The evaluation established that the standard routing is used, except where circumstances require another solution, e.g. during construction work. The objective of improving the predictability is met.
