Pedestal Objects

This is an example of how hazardous pedestal phone booths are as the base is narrower than the top and no warning is provided by the cane of the head height hazard.
This is an example of the problem of how chains between bollards arehazardous as the cane does not provide a warning of the impending hazard.

Pedestal objects usually have above ground dimensions greater than their base. These include telephone booths on stands, tables, benches, chains between bollards and railings with no lower sections. People using long canes may not be able to detect these raised objects in time to prevent colliding with them.
Because the boundaries of accessible paths of travel are often unclear, Guide Dogs NSW/ACT recommend that no pedestal objects are used in public places. The pathway around all existing pedestal objects in public places should be clearly defined, using both textural and luminance contrasts. This may require the installation of Tactile Ground Surface Indicators (TGSI).
