Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius

Traffic management is not formally organised in the maritime domain. Ships are autonomous and find their own way. Traffic is organised through rules, regulations, and “good seamanship”; it is a distributed system. In areas of high traffic-density support is proved by vessel traffic service (VTS) to promote traffic safety and fluency. VTS does not take control. This organisational structure has proven itself in situations with sufficient resources. When resources become insufficient (e.g. not enough sailing space), the traffic needs an organising mechanism. In this article, the authors argue that the most promising way to do this is by organising centralised …

Situation Awareness And Maritime Traffic: Having Awareness Or Being In Control?, Fulko Van Westrenen, Gesa Praetorius

Situation awareness (SA) is generally seen as a mental representation of the system state, an objective measure of the ‘situation out there’. In this article, the authors make an argument that SA can only have a meaning in relation to the task of the user and characteristics of the system. This will be argued with the help of a specific environment: vessel traffic monitoring. The long-time constants and the complex constraints imposed on the ship require that the operator monitoring the traffic has a good SA: the operator must make long-term predictions about possible traffic developments. For this, being in …
