Yes, they need to. So that is a wrong placement of the stations. Ideally, you don’t really want to use those big stations here for buses or trams as they just clog everything up. My biggest annoyance with them is that passangers coming and going across the entrance to the tram/bus station will block it and my buses/trams will always have to wait until it’s clear. And on large busy cities, it’s pretty much never.
What i do instead, is just place a normal stop along the road, or build a road for it parallel to the main road, allowing buses and trams to turn around easily, if needed. Stop is also always placed after the pedestrian crossing so people exiting the vehicle will go across the road behind it, leaving free road in front of the vehicle for it to depart.
