IHE Passive Safety Electrical Guide 2021 published
- Thursday September 9, 2021
The Institute of Highway Engineers (IHE) is pleased to announce the publication of the new IHE Passive Safety Electrical Guide 2021.
The Guide, written by Alistair Gollop of Mott MacDonald on behalf of the Institute of Highway Engineers, details the electrical requirements for passively safe ITS roadside installations to BS EN 12767. The necessity for the new guidance document has been heightened due to changes in the current version of the BS EN 12767 standard, which includes the removal of electrical requirements from the National Annex. Due to the complexity of cable arrangements found in typical ITS installations such as traffic signals, this omission poses potential problems to practitioners undertaking the design, specification or management of ITS equipment.
The guide examines why Impact Electrical Isolation (IEI) systems should be considered when designing any roadside ITS installation, including those mounted on passively safe or traditional structures. It looks at why an IEI system may be required in addition to standard electrical protective devices, the different types of IEI solutions which are commercially available in the UK, and how the selection of the type of pole and column should influence the IEI technology used.
Speaking ahead of the launch Steve Spender CEO of the IHE said, “IHE continues to provide resources to its members and we are pleased to have worked with Alistair on producing this guidance. We are especially delighted to be launching the Guidance at the 26th JCT Traffic Signal Symposium on 16th September at Nottingham Trent University, one of the first major events to be held since COVID restrictions started to ease.”
