Introducing a major advancement in measuring skid resistance and interrelated road surface characteristics, the intelligent Safety Assessment Vehicle, or iSAVe. The iSAVe provides a major advancement in terms of measuring skid resistance and inter-related road surface characteristics. Developed in conjunction with our Swedish partner, SARSYS-ASFT and working under license to the UK Transport Research Laboratory (TRL), ARRB Systems new iSAVe is manufactured in full compliance with the current British Standard BS 7941-1:2006.

The iSAVe is typically used to measure the wet skid resistance of defined sections of road surface across a network in both wheel paths, to help ensure that an appropriate level of ‘grip’ is provided throughout. An emphasis is placed on high demand locations, such as the approaches to traffic signals and pedestrian crossings, around tight curves etc., where vehicles are typically required to brake and accelerate, sometimes in emergency situations. In short, the iSAVe supports positive road safety outcomes.

Along with the collection of wet skidding resistance, the iSAVe is fitted with sensors capable of collecting:

■ Roughness (IRI)
■ Rutting
■ Macrotexture (MPD and SMTD)
■ Geometry (slope, crossfall, gradient)
■ Asset inventory imaging
■ GPS and distance.

The iSAVe is also fitted with the following additional features to minimise measurement variability:

■ Dynamic monitoring of vertical load
■ Continuous tyre pressure monitoring
■ Dynamic speed-controlled water system
■ Ambient air temperature monitoring
■ Tyre temperature monitoring
