Abstract

This paper reports a pilot investigation into: the relationship between the users' perceptions of ride quality and an objective measure (NAASRA Roughness); how acceptable is a specific level of road roughness for trips of different length; and how far are users prepared to travel to avoid rough roads. The investigation was undertaken by the Australian Road Research Board at the request of AUSTROADS and was part-funded by AUSTROADS. Its aims were: to detect changes in users' perceptions since a similar study in 1972; to assess the variation in perceptions around Australia; and to assess the variation in perceptions with population density. Panels (drivers and passengers) were used to rate a variety of roads at different travel speeds. The 1990 and 1972 ratings of ride quality are described- there were indications that the ride had improved on some types of roads. As road roughness increased, users were prepared to drive further to take advantage of a smoother alternative route. Recommendations are made for further work to overcome the limitations of this pilot study.
