One-way streets, banned turns and no-entries help to control traffic movement without fully restricting road access. They can stop commuter 'rat-runs' during one peak period only.
One-way restrictions may affect the whole length of a street or a section at one end. A good alternative route must be found for traffic travelling in the opposite direction to the one-way street or turning in the direction of the ban. This alternative should not normally be via a residential road.
One-way streets often lead to an increase in traffic speed. Short lengths are difficult to enforce if drivers are irresponsible enough to drive the wrong way. However, this is dangerous and can result in penalties, as mentioned in the Highway Code.
Some residents find one-way streets and banned turns inconvenient as they can increase journey times.
