Trafikanternas krav på vägars tillstånd: sammanfattande slutrapport

The road condition on all state roads is routinely assessed by road surface condition measurements. Surveys among private motorists and professional drivers are also conducted to find out how satisfied or dissatisfied users are with the operation and maintenance of the state´s roads. In short, the correlation between the objective measurements, carried out to assess the road surface condition (or rather, the road condition indicators used) - and road user's opinions are not particularly good. A number of sub-studies have been carried out within this project to provide ideas on how to ask questions about the road condition to obtain the best possible subjective data. The sub-studies also gave impetus to which objective data should be gathered in future to help improve the correlation between subjective and objective data. The sub-studies included a literature study, a focus group study, a questionnaire study and a driving simulator study.
