Ride Quality Measurement and User Ratings: Initial Assessment of Improved Techniques

Improved techniques for assessing ride quality have been developed by the authors that closely simulate actual vehicle ride dynamics and the responses of humans to whole-body vibration. Using numerical models to simulate four generic road-user vehicle classes – passenger cars, heavy commercial vehicles (trucks), off-road recreational and sports utility vehicles (SUVs) and motorcycles – fundamental issues associated with current ride quality measurements are addressed leading to more robust and accurate estimates of pavement rideability. Initial field trials and tests of the proposed ride quality model for a passenger car were conducted. To assess the effectiveness of the model as a ride quality predictor, the overall modelled ride responses were compared with actual measured ride vibrations (objective measures) and road-user ride ratings (subjective measures), all taken on the same sections of pavements. For the objective measures of ride quality, portable vibration measuring equipment, comprising accelerometers, event markers and a data logger, were assembled, customised and tested. In later versions of the equipment, also described in this paper, Global Positioning System (GPS) tracking was incorporated to provide precise time-based recordings of location and speed. Developed specifically for this project, the equipment is small in size, completely self-contained, and is readily adapted for use in both small and large vehicles (motorcycles, cars, SUVs and trucks). The initial study found there was good agreement between the modelled responses, vibration measurements and subjective ratings. A further larger study is planned which is discussed in this paper.
