The ride quality of an unsealed road is a major performance indicator of driver and passenger perception of comfort and safety. In response to market demand, ARRB Transport Research has developed the 'Roughometer', an affordable roughness measurement device for unsealed roads. This device will provide practitioners with an objective assessment of ride quality or road roughness calibrated to either NAASRA Roughness Measurement (NRM) or the International Roughness Index (IRI). The Roughometer has been developed to be practical, easy to use, robust, low cost, portable and provide reasonable accuracy. The purpose of this paper is to describe the research undertaken to define the market demand and user specifications, the technical development process, results of field trials and the appropriateness of the Roughometer to meet user requirements.
