The missing goods service is also an important service within the STM framework as it ensures that no goods are left behind and thereby increases the delivery reliability. Although the transport notification service is not directly going to increase delivery reliability, it enables notifications to receivers about delays and by that makes it possible for the receiver to respond much earlier to events. The same applies for arrival notification service that allows the receiver to prepare unloading of shipments in due time and plan for truck arrival if many trucks are arriving at the same time.
