Passive Safety Design in UK Street Lighting

The authors explain the concept of roadside passive safety and look at how it affects street lighting design. Many accidents involve collision with a roadside feature; consequently passively safe lighting columns are becoming increasingly available as their forgiving design can help save lives. Highlighting how new this is in the UK, the authors briefly compare its usage over the years in USA, Australia, Norway and Finland. They explain how the columns need to be designed and manufactured to achieve the right level of yield, shearing or deformity when hit be a vehicle. Without passive safety design, columns need a continuous protective restraint system around them, yet the restraint system itself can often be hazardous. The authors believe passively safe columns will provide reduced accident severity through vehicle impact compared with standard columns, and thus provide social and economic benefit. However a method to quantify this is still required. The technical features of the columns are summarised, including design, absorption, size, materials and electrical connections. Tables summarise passively safe column classification, energy absorption categories and occupant risk. Also included is an explanation of The Passive Revolution, a campaigning group which targets engineers to raise awareness of passive safety issues.
