Leading Bus Interval (Queue Jump) in Cities Skylines

Giving the buses their own exclusive bus lane at intersections and timing the traffic lights to give buses a very short headstart on the other through traffic allows the buses to quickly pass congestion at busy intersections. This can be applied to longer dedicated bus lanes, or just for a very short queue jump bus lane that only exists at the intersection itself.

That center bus lane is very interesting! Is it part of a mod?
