A large road hump across the width of a carriageway (or a cycle track). Has a flat top and can either run kerb to kerb or stop short to leave a channel for water to pass. Used on cycle tracks where grade separated from the footway to provide a pedestrian crossing point. Can be used to provide a level surface at pedestrian/ cycle crossings of carriageways. If used on a separated cycle track crossing a carriageway, cycles can be given priority over traffic. Sometimes used at a junction in the side road or across the entire junction.
