Abstract
Traditionally roadside signs are supported on tubular steel circular hollow section (CHS) posts. A variety of sizes and configurations are used, dependent on the size of the sign to be supported. The HA have recently updated their documentation and introduced two new documents Interim Requirements for Road Restraint Systems (IRRRS) and Non-Proprietary Safety Barrier Systems (NPSBS). To support the new documentation it was decided to conduct a series of impact tests to establish the largest size of unprotected single steel tubular sign support posts that can be allowed on the HA Road Network.
