Hello, here I bring some of the changes I have introduced in layout of the map taking into account your advice, I tried several combinations of routes and in my opinion this is the most fluid, please tell me what you think.
The connector (Orange routes) one of the routes block it and in the remaining route place a small step so as to penalize the time in CT or T to A.
The other possibility of rotation paths from medium to B was blocked.
One of the combinations of routes from CT to B was also blocked so as to limit options and simplify the map in some way.
