A key element in the successful maintenance of a road network is the availability of accurate, reliable and consistent survey data. To this aim, Highways England commission annual accreditation trials for Sideways Force Skid Resistance devices supported by ongoing QA for the devices. In order to undertake accredited surveys, the survey devices are required to meet the mandatory criteria of the trial.
This report covers the 2015 trial run by TRL and held on the Horiba-MIRA proving ground between 28th and 30th April 2015 and on the Longcross test track on 27th April 2015.
