DOWNLOAD EBOOKTo estimate the future volume of trips interchanging between each pair of zones within an urban area, a simple behavioral model of travel interaction is presented. The interactance model is subjected to a set of five constraints, which reflect pertinent conditions that should be fulfilled in the resulting distribution. A method is developed to distribute future trips in accordance with the interactance model so that all constraints will be satisfied. The constrained interactance model differs from other trip distribution models in that the distribution of trip lengths is constrained to result as given in advance. Furthermore, no model calibration is necessary. Rather than the conventional use of subjective judgements to distinguish the travel movements which warrant exogenous compensations to correct for socioeconomic biases, an objective procedure utilizing a statistical test is provided. Socioeconomic and geographic compensations, where needed, are applied between pairs of groups of contiguous and homogeneous zones rather than between individual zone pairs. A model is developed to determine the total number of zone pairs expected to have travel interactions in an urban area, as a function of the number of trips and zones. Another model which describes travel interaction propensities as related to travel disutility, is developed to indicate which pairs of zones are the least likely to have travel interactions, and should be dropped from the trip distribution, in order to restrict the number of travel interactions to the estimated total. ...

DOWNLOAD EBOOKFirst published in 1970, this groundbreaking investigation into Entropy in Urban and Regional Modelling provides an extensive and detailed insight into the entropy maximising method in the development of a whole class of urban and regional models. The book has its origins in work being carried out by the author in 1966, when he realised that the well-known gravity model could be derived on the basis of an analogy with statistical, rather than Newtonian, mechanics. Subsequent investigation demonstrated that the entropy maximising method stems from an even higher level of generality, and the beginning of the book is devoted to an account of its importance and use as a general modelling tool. This reissue will be welcomed by a range of students and professionals from fields as diverse as urban and regional studies, economics, geography, planning, civil engineering, mathematics and statistics.
