Objectives:

The study aimed to establish how best to manage erection of temporary traffic management in the central reserve with concrete barriers present.

Methodology:

The study established current maintenance practices through stakeholder consultation. It reviewed existing sign mounting measures available from sign manufacturers and those used abroad.

Key Findings:

  • 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.

Themes:

Concrete barriers, temporary traffic management signs

Comments:

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.
