BibliographicSection relationships among links in a recreational trip chain applies Hggerstrand’s concept of the individual’s Action Space in a recreational environment. Empirical input to the simulation consists of evidence on the effect of the vacation length distribution on recreational travel behavior, the spatial hierarchy of recreational trip chains and the impulsive motives characterizing recreational travel at the local level. In addition to producing relationships between the average vacation length and the model’s variables in the case of a bounded linear network, we study the relationships between the average length of stay at a recreational location, the accessibility of that location and the average vacation length. Results of this study seem to point out that a Gamma function is a more appropriate general representation of the distance effect on recreational travel behavior. Finally, the relative success with which the model was calibrated in a case study of the visitor flows to the Greek Islands of Cyclades indicates that future efforts to systematically collect data and develop the model are warranted.
Cost Analysis of Inland Water Transportation Systems for Developing Countries, Sergio de Vasconcellos,
147
Instituto de Perquisas Technologicas, Caixa Postal 7141, Sao Paulo, Brazil. (Dissertation in the Department of Civil Engineering, University of California, Berkeley, CA 94720.) A cost analysis of inland water navigation systems is developed. The study is specifically devoted to the planning and implementation of small to medium size waterway systems under conditions most likely to be encountered in developing economies. It addresses the problem in a sufficiently broad frame to describe several options when diverse systems development may be needed. The study analyses major acquisition, operation, and maintenance costs of selected waterway components. It is developed using the production function approach in which cost models are developed for each separable process. The models have the form of cost functions, obtained from production functions by multiplying them by cost coefficients. The cost coefficients are developed from current market prices by adopting suitable assump tions. The results are presented in tabular form rather than a single mathematical expression. Information is provided to allow potential users to derive their own cost coefficient for particular cases. Default figures are provided for use when no other data are available.
Brfef Notfces Symposium on Transportation Issues, Kathi Luckard and
Dorothy Berks, Editors. McLean, Virginia, 1975.
The MITRE Corporation,
This is a report of a three-day Transportation Symposium sponsored by MITRE in September, 1975.The purpose of the Symposium was to articulate the major transportation issues, and to develop general recommendations in each of the transportation sectors considered. Various speakers addressed the key topics which included the Congress and transportation, urban transportation, intercity rail transportation, motor carrier transportation, air transportation and Department of Transportation policy. As well as these talks, which are fully transcribed in this report, panel discussions were held on transportation regulation, urban transportation, air transportation, transportation of freight, transportation R&D policy, intercity ground passenger transportation, and automobile issues. This report includes a summary of each discussion, citing the various recommendations and proposals which were presented.
Eflect of Productivity and Technological Progress on Transport Workers, N.H. v.d. Woude, G. Schuh and R.
W. S. Pryke, European Conference of Members of Transport Round Table 26, OECD, 2, me Andre-Pascal, 75775 Paris Cedex 16, 1974. The importance of this Round Table discussion comes
from the fact that labor usually accounts for a substantial part of the total costs of a transport undertaking. Three introductory reports cover the conventional sectors of inland transport-road, inland waterways, and rail. (Even though there was no separate report on urban public transport, a large part of the discussion was devoted to it.) A summary of the ensuing Round Table discussion on labor economics, in which not only research scientists, but also transport employers and workers participated, is then presented.
Management of Tmnsportation Carriers, Grant M. Davis,
Martin T. Farris and Jack J. Holder, Jr., (Praeger special studies in U.S. economic, social and political issues), Praeger Publishers, 111 Fourth Avenue, New York, NY looo3, 1975. While considerable literature exists today which is devoted to the shipper or user side of transportation, very little exists on carrier management. Written in the belief that transportation is the major exception to the truism that “management is universal”, this book discusses transportation solely from the viewpoint of carrier management. Part I, “Regulatory Concepts: A Factor in Transportation Management,” begins with a general discussion of the transportation system, and then sets forth in detail the five constraints faced by carrier management that make transportation different: the regulatory environment in which it operates; the given
