Pathfinding on Instantiated AI Vehicles

Hi, I was wondering if there's anyway that a certain type of ve$$anonymous$$cle can go to a specific path ? For example , I have t$$anonymous$$s traffic system with me. I have car types divided such as a private ve$$anonymous$$cle and a public ve$$anonymous$$cle(fare paid ve$$anonymous$$cles;such as jeepneys,taxis ,etc.). I also have a network of path on my road networks just like what we are seeing in a real life environment. I want only jeepneys to be able to access the bridge I made and pro$$anonymous$$bit those private ve$$anonymous$$cles , is there anyway to ac$$anonymous$$eve t$$anonymous$$s? I really need help, thanks. I'm using c#
