Measures usually taken in conjunction with traffic management schemes to assist bus traffic are: (1) prohibition of traffic other than buses on a certain street, (2) one-way schemes - while increasing speeds, these result in longer distances, (3) bus lanes arranged either at the side or in the centre of a street, (4) traffic lights with bus priority. Priority can be either passive or active. Prohibitions and restrictions are often insufficient since other traffic ignores them, and engineering measures therefore have to be taken. These can be: (5) construction of bumps or depressions, (6) staggered narrowing of carriageway on alternate sides, (7) narrowing of carriageway at certain points, (8) rumble strips or surfacing different from rest of carriageway. Bumps or depressions, staggered or narrowed carriageways achieve about the same reduction in speed. However, the easier an obstacle is made for a bus, the easier it will also be for cars to pass over it. Trials have also been carried out using barriers or booms which can be opened either automatically or physically by buses, or depressions at narrowed portions of the carriageway which can be straddled by buses but cannot be passed by cars owing to a kerb in the centre which is higher than a car's ground clearance.
