Community levels of service for local roads

The paper presents the methodology and outcomes of 8 separate investigations undertaken from 1998 to 2004 to assess local road users' expectations of levels of service on local roads. Road user groups, or panels, ranging from eight to forty three people, represented the communities that used particular road types in the assessment process. These roads ranged from unsealed to sealed local roads. The road users were surveyed for their assessments of levels of service. All investigations covered the assessment of the factors that influence road users' perceptions of levels of service and quantitative assessments of the maximum acceptable level of rideability or roughness of the roads. The investigations have shown so far that communities often have unique perceptions and requirements. In reviewing all 8 investigations, rideability ranked as the second highest factor thought to influence road users' perceptions of road conditions after potholes. The road user surveys provided estimates of acceptable roughness based on: (1) rating and roughness relationships; and, (2) the percentage of acceptability and roughness relationships. The relationships from (2) were usually more statistically significant and a better fit to the data than the relationships from (1). However, in using the relationships from (2) to estimate acceptable roughness there is the issue about what levels of percentage of acceptability are used to set roughness limits. The estimated acceptable roughness was also found to have a tendency to increase with reducing the test speed.
