At uncontrolled crossings pedestrians do not have priority over vehicles and must make a decision about whether it is safe to cross.
The following locations are described as uncontrolled crossings:
The blister surface should be buff or any colour (other than red) which provides a contrast with the surrounding footway surface. The contrast in colour assists partially sighted people to identify the presence of tactile paving and hence the presence of a flush kerb. In no circumstances should the red tactile surface be used at uncontrolled crossings. Red is strictly for controlled crossings only.
The blister surface should be installed the full width of the flush kerb. The depth of the surface will depend upon whether the flush kerb is in the line of pedestrian travel.
The purpose of the tactile surface is to compensate for the absence of a kerb upstand.
The back edge of the tactile surface should be at right angles to the direction
of crossing. This may not necessarily be parallel to the kerb. Some visually
impaired people use the back edge of the tactile surface to
align themselves correctly in the direction of crossing.
