Scottish cycling pavement assessment using hand–arm vibration exposure

Abstract

A defective pavement surface discourages cyclists from selecting certain routes, and vibration exposure is a noticeable consequence of reduced path surface quality. Current asset management practice includes walkover surveys and cyclists reporting defects directly to the local authority. This research proposes the use of an instrumented probe bicycle to collect data for the assessment of pavement condition and rider comfort. Furthermore, the collection of hand–arm vibration exposure data is proposed as a means of assessing pavement surface condition and suitability. Hand–arm vibration exposure has been measured in compliance with BS EN ISO 5349-1:2001. Root-mean-square vibration total values, vibration dose value and exposure values (15, 30 and 60 min) are provided for 13·682 km of pavement surface in Edinburgh, Scotland. The vibration exposure values are compared to those recommended by EU Directive 2002/44/EC. Power spectral analysis is also performed to determine the power transferred to the cyclist’s hands and arms. The collated vibration data may be used as a means of assessing pavement surface condition. Such data may prove beneficial for local authority asset management associated with resurfacing or repair works.
