The study aimed to establish how best to manage erection of temporary traffic management in the central reserve with concrete barriers present.
The study established current maintenance practices through stakeholder consultation. It reviewed existing sign mounting measures available from sign manufacturers and those used abroad.
Traditional temporary traffic management ‘A’ frame signs typically cannot be used as designed when a concrete barrier is present, i.e. they tend to straddle the barrier without touching the ground and require weighing down with sandbags.
Provision of temporary or retro-fit brackets provide solutions for securing temporary traffic management signs. Eyelets at regular intervals are a potential alternative.
Vertically mounted sockets to accommodate temporary traffic management signs are possible only on wide concrete barriers which already accommodate lighting columns.
It is not desirable to present a ‘one size fits all’ solution – the most effective methods tend to be site specific.
Concrete barriers, temporary traffic management signs
This report identifies potential solutions for safe and rapid erection of temporary traffic management signs on / adjacent to concrete barriers. This report does not make use of physical trials, but recommends that these be carried out.
