Abstract
Due to the extremely dense usage of city roads, road users always pay high attention on the roadway service quality. Although road authorities have been devoted into improving the road smoothness through years, patches and manholes are still two main distresses that receive most of the complains from road users. Some practical researches had been studied in the past, but the effects of utilities cut were seldom to be probed into.
The regulations of utility cut practiced in some major cities of Taiwan are discussed in the thesis. The current conditions and the difficulties of implementing these regulations are presented through interviewing the road administrative agencies. Suggestions for improving the efficiency and practicability of the regulations are brought up. In addition, by integrating the international roughness index（IRI）, pavement condition index（PCI）, and various types of pavement distresses including manhole, a linear regression model of smoothness prediction is developed in this study. This model provides the authority to evaluate the quality of urban road.
