How to managed restricted area

Hi,
Is there a way to steer clear of restricted routes such as dead ends and detours in Mappoint ?

I would like to create may own restricted area but also used one already existing such as weigth limitation and so on.

I'm writting a c++ software to build routes and i need to take in account this king of problems

Thanks for the help
