ABSTRACT

This paper presents the findings of an empirical study of work trip rates and patterns in urban Kuwait. The study uses census information collected in 1980 and supplemented with data on the road network coded to the urban arterial level. Work trip production and attraction rates for different sub-population groups are provided along with a set of simple regression equations that may be used to model trip production and attraction magnitudes. Observed trip linkage patterns are presented. A set of gravity-type singly- and doubly-constrained spatial interaction models are calibrated for each population group using the 1980 observed work trip linkages data and an automatic calibration technique. The capabilities of these models in reproducing observed trip linkages patterns are evaluated on the basis of a graphical analysis of residuals.
