Bus priority signal

Bus priority or transit signal priority is a name for various techniques to speed up bus public transport services at intersections (or junctions) with traffic signals amongst other methods. Trams and light rail vehicles can also be given priority. Buses normally signal their impending arrival (for example via radio systems) and on their arrival at the intersection receive green lights. This is often combined with separate bus lanes, though possibly this may only apply at the intersections themselves.
