PAF have the benefit of highway engineers that are specifically trained and experienced in forensic investigation, highway design, road safety auditing and enforcement and therefore fully understand the consequences of a deficient highway and its associated furniture.
Best practice is that a full investigation of fatal and life threatening collisions should be investigated to determine if the highway assets were a contributing factor towards the cause of the crash.
PAF can mobilise their engineers to crash sites to conduct full and detailed engineering investigations. Details of highway layout are noted with special emphasis on safety features. Specific factors that are assessed include geometry, alignment, vehicle restraint systems, drainage, street lighting, road surface condition & characteristics, signals, signs, road markings, sight lines.
Other factors such as traffic density, traffic speeds, product approval and maintenance records are considered.
