The traffic facilities that the Swedish Transport Administration plans, builds and maintains are a central and important part of most Swede’s everyday-environments. Through comprehensive studies in an R&D project, the Swedish Transport Administration has developed a tool for measuring how customers perceive a certain road environment. The tool, Customer-perceived quality in the traffic environment, allows statistically reliable measurement and evaluation of the design quality in our traffic facilities. By applying the method, we can ensure the quality of design early in the process, long before the project is built which strengthens the social benefits and increases customer satisfaction.
