An Extremal and Information-Theoretic Characterization of some Interzonal Transfer Models.

Abstract: : The paper develops a method of deriving gravity models from extremal principles. The prototype result yields the most popular gravity flow model characterized by an extremal principle. This principle is also for the first time elucidated as an information-theoretic one of choosing the distribution of interzonal transfers which gives least information (in the technical sense) for discrimination against a distribution reflecting the facility (reciprocal of the difficulty) of travel between zones.

Regulatory Models for Pricing and Evaluation of Transport Services

Abstract: A variety of objectives and constraints are presented for use by a regulatory agency in pricing public services and evaluating capacities under conditions where the demands are random variables with probability distributions that depend on prices in different parts of the system. The models studied include a maximization of the joint probability of achieving at least specified levels of consumers' surpluses in these interacting markets, as well as models that constrain the choices of prices and services to ensure that these surpluses are satisfied to at least specified levels of probability, while observing expected fair return constraints for the producers. Chance constrained programming formulations and reductions to deterministic equivalents are developed to use for evaluating levels of service, etc. Some new “coefficients conditions” establishing concavity for quadratic forms are stated and proved in the Appendix to this paper. This also establishes convexity for the deterministic equivalents develope...

Information Requirements for Urban Systems: A View into the Possible Future?

Abstract: The successful management of urban systems is becoming increasingly a matter of successful information about the urban area and its environment. Using information as a basis for developing a structure for, and outlining the flows in, an urban area, this paper develops a dual hierarchy of information requirements and management activities. Each level of the hierarchy is discussed in terms of the emergent problems and requirements that are likely to confront management scientists and urban administrators in the future. As the information requirements of urban areas become more complex and as the components of the urban system become more highly interrelated, developments in information technology can be expected to have a direct impact on the activities of urban area administrators. This development is illustrated here through the presentation of a selected number of possible impacts of information technology developments upon the information and management hierarchies of urban systems.
