This publication examines a variety of cases that demonstrate the aesthetic quality of transportation projects. These range from the relatively inexpensive painted "Gus Bus" in Grand Rapids to the large-scale project of designing the Montreal Metro. The purpose is to develop a fresh perspective on ways the visual appeal of transportation can be identified as a distinct element for consideration, and on the degree to which quality design contributes to the economics and function of transportation systems. A second purpose is to develop guidance and examples to assist transportation planners and citizens in dealing with these issues. The projects presented represent a wide range of costs and circumstances encountered in transportation planning. The study shows that the aesthetic benefits provided by quality materials, sensitive design, careful maintenance, and appropriate inclusion of works of art translate directly into increased patronage, cost efficiencies, and a better public environment.
