Block areas with Landmark

Open Source Routing Engine

Hello!

I have a question about the usage of areas and Landmarks.
I need to block areas on the fly (as dynamically as possible), so in every request. So I though on passing them on the custom model areas field with priority = 0. The point is that I want to affect to the performance as less as possible.

So my question is, if I configure a landmark profile, this will help to keep the performance for my specific requirement of restricting areas dynamically?

Thanks in advance.

Yes. Performance will depend on the size of the blocked areas. If they are very large, such that the resulting route changes dramatically performance will become worse, possibly worse than simple A* without landmarks. Otherwise using landmarks will be very beneficial compared to A*.
