Within CoRISMa different levels of Corridor Management were defined requiring specific information services:
Corridor Management is a service to enable reliable route planning by supplying dynamic and static infrastructural information (Fairway Information)
This is the basic level. It deals with the hard infrastructure information and provides the fundamental fairway information required for route planning. On this level, questions are answered such as: How many locks are on the way? Are they open? How are the actual water levels? Where can that information be obtained?
The main task here is to provide fairway information from the point of origin to the final point of destination.
Corridor Management is a service to enable reliable travelling times for voyage planning and for traffic management, by providing traffic information
This level builds on the previous one, adding traffic information to Corridor Management. It’s logical: Once you have the infrastructure information you need the actual traffic image. You are looking for information such as: How many vessels are on the fairway? What is my estimated time of arrival?
To know the traffic situation on a Corridor allows the stakeholders to plan their voyage better, or to know the position of specific vessels on the waterway network
Level 2 is further sub-divided into – Level 2a: Taking into account the actual traffic situation (e.g. actual traffic density, actual waiting times) – Level 2b: Also taking in account predictions during a voyage (e.g. predicted traffic density, predicted waiting times) where considered reasonable
Corridor Management is a service to support transport management of the logistic partners (e.g. deviation management)
This is the last level, which therefore builds on Levels 1 and 2, and introduces a new dimension: Third party information for logistics and transport management purposes
Private stakeholders within the logistics chain can benefit from customised services providing specific relevant information (e.g. vessel position information or estimated times of arrival of specific vessels for authorised logistics users, voyage and cargo reports), enabling increased efficiency within the logistics processes
