Although, there are already different solutions, these are installed on the quays which would lead to a high costs on the authority side due to infrastructure changes. Which raises questions around scalability knowing Flanders has over 100 locks. Note: the current solutions are mostly maritime.
Important to mention is that some variations are being developed so the solution could be implemented on the barge instead, which makes sure the infrastructure investment is limited. However, this could lead to significant investments for the barge operator, which then raises the question if it is still possible to create a positive business case.
Some of these technological solutions can be found below:
