Priority narrowing involves introducing road narrowing which creates a one-way priority system at that point. The speed reducing effect relies upon the regular presence of oncoming vehicles in order to ensure that traffic without priority has to periodically give way and consequently reduces its speed.
Success with priority narrowing and priority chicanes can be difficult to achieve as they rely heavily on the good visibility from approaching drivers. The presence of private drives and side roads also restrict the opportunities where priority narrowing can be placed.
A single priority narrowing with associated signing and road markings may cost approximately £24,000.
