At head of title: National Cooperative Highway Research Program.
Soon after starting work on the development of a methodology for national trans portation planning in Venezuela, we realized the importance of an integrated management process for such an effort. We also realized the absence in the literature of specific guidelines on how to manage and conduct a transportation planning effort. The literature on the subject of national transportation planning is predominantly theoretical and technical in nature. To a large extent, the absence of literature on management and broad-based methodological approaches reflects the limited and ad hoc nature of the experience in national transportation planning. This book is an attempt to fill that gap. The main objective of the book is to show one way by which a methodology for national transportation planning can be integrated into a process management framework. It reports on the experience that the authors had in the Venezuelan case, as well as in earlier national planning efforts. The book is not intended as a theoretical discussion of planning. Instead, it adopts a particular theoretical stand and proceeds on that basis to develop a program for applying a specific methodology. The intention is to leave as much of the details and elaborations of that methodology to the user. This is motivated by two considerations. The first is a pragmatic attempt to limit the scope of the book.
This book provides information concerning the costs of transportation on non-urban highways and the relationships between these costs and characteristics of highways such as surface roughness, and vertical and horizontal geometry. The sources of the information presented here are four major road user cost studies performed between 1970 and 1982 in Kenya, the Caribbean, Brazil, and India. In these studies road user costs were investigated in considerable depth. Surveys of commercial road users were performed, surveys on a far larger scale than had been conducted prior to the 1970s. Large scale experiments were undertaken, aimed at determining the fuel consumption of cars, buses and light and heavy goods vehicles under alternative highway conditions, and considerable effort was devoted to obtaining data on vehicle speeds and their responses to highway conditions. The resulting body of knowledge concerning road users' costs is enormous, spanning three continents, diverse highway conditions and radically different economic environments.
This book considers the problem of providing maximum access to transport services, and to roads for the rural population of the world's developing countries when limited funds are available. Access is a key factor in both social and economic development. It promotes social intercourse and opens up markets for both the rural and urban populations. Access connotes the ability to travel and to transport goods. The components of access include both the infrastructure and the transport modes or aids that use the infrastructure.
