FUTURE DEVELOPMENTS IN HIGHWAY TRANSPORTATION part 1
Technological advance has been great during the age of modern highways and continues today. Knowledge has been extended in the fields of soils and other highway materials and the designs using them so that they are now more economical and reliable. Developments in machinery and management techniques have revolutionized construction and maintenance methods. The highway engineer has become increasingly conscious that a highway can be attractive and safe as well as useful and has learned much about roadside improvement, erosion control, and noise abatement. Entirely new approaches have been developed in the fields of highway and urban transportation planning, geometric and structural design, and traffic control. In all of these areas the computer has be¬come an essential tool. Many challenges lie ahead for those interested in re¬search, design, and administration as present practices are refined and new approaches are developed.
Possibly the most difficult problem now facing highway and transportation planners, engineers, and administrators is to define the role of the automobile, highway-based public transit, and other ways of moving people and goods in urban areas. Currently, critics are blaming the automobile for such problems as urban area expansion and wasteful land use, congestion and slum conditions in the central areas, and air and noise pollution. These problems are aggravated by a crisis in petroleum-based energy supply. It follows that those who will plan, construct, maintain, and manage our transportation facilities face a changed world; the problems in the 1980s are not those of the 1950s, 1960s, and early 1970s where the target was to build a system of freeways and other major arteries to accommodate expanding demands for better mobility by automobile. Rather, efforts will be directed toward making minor additions and adjustments to that system, rehabilitating it so that it does not completely fall apart under the ravages of time and heavy traffic, and operating it for maximum efficiency and safety. To search out, demonstrate, and implement viable approaches that will help solve these problems will challenge the ingenuity, abilities to deal with people, and staying power of all in the years ahead.
