For a customer we want to plan shipping routes on inland fairways. We've implemented a custom evaluator to calculate the cost in time a specific element (points) on this route can cause.
Now what I would like to find out is the direction (along or against digitized) of the route that is being calculated when this point is reached when solving the route, because depending on the direction a certain cost must be taken into account or not. Is this possible from within a custom evaluator and what would be the best way to retrieve this information?
Thanks in advance for your suggestions.
