PLANNING OUR URBAN EXPRESSWAYS

Traffic and highway engineers are faced with complex problems in the design of urban expressways in American Cities, but no problem is more difficult than integration of the expressway plan with the existing urban street system. As the United States has become progressively more urbanized and motorized, a closer relation between transportation and urban development has become essential. This article discusses how we will have to plan transportation facilities to achieve better communities and community planning will have to be designed to achieve better transportation. The development of an efficient urban expressway requires more than putting together of such elements of expressway design as through-lanes, merging and weaving areas, ramps, emergency stopping lanes and interchanges, which the designer expects will be capable of accommodating traffic demands twenty years in the future.
