Truck Mounted Attenuators (TMA) are widely used on New Zealand Level 2 and 3 state highways and on some network roads that carry high-volume high-speed traffic, to provide safe environments for both roadwork crews and road users. They are used for static, semi-static and mobile operations carried out on sealed carriageways. However, current practice (specified in the 3rd edition of Transit New Zealand Code of Practice for Temporary Traffic Management (CoPTTM June 2004)) has not prevented 39 TMA incidents occurring in the past five years (July 1999 to July 2004), including four fatalities, as well as numerous injuries. Rather than enhancing safety, the VES currently used on TMA have the potential to adversely affect driving, and to create unsafe circumstances by providing drivers with inefficient messages.

Post-crash care of victims is considered by the World Health Organisation to be the fifth pillar of the safe system approach to road safety. Timeliness and quality of transport of crash victims from the crash site to hospital door is crucial to medical outcomes. It is important that road controlling authorities (RCAs) and Road Policing work together with Emergency Services to provide the best possible outcomes for the available resources. This report considers the roles of RCAs and Road Policing in facilitating transport of crash victims from the crash site to the hospital door. The report includes a literature and technology review, a crash analysis and estimates of the time from crash notification to hospital. Also considered are issues arising from a workshop of stakeholders and an online survey of front-line staff from Road Policing, St John and Fire and Emergency New Zealand.
