Hi everyone - I have built a network using data from https://extract.bbbike.org/ as I want to model the impacts of potential new driving restrictions.

At a crossroads, I want to prevent left hand turns but allow vehicles to continue travelling straight on or turning right. Can this be built into the network, or alternatively, can a barrier be created when creating a route in network analysis?

Any help is much appreciated!

One option is you can create a turn feature class and model all the turns you want restricted in your network. Doing this will allow you to limit what segments can be turned onto from other segments.
