This report represents that conclusions of the first year of IURD's study of the potential for a high-speed passenger train service in California. Seven previous studies have each dealt with a specific high-speed train technology; each attempted an evaluation, standardized so far as data...

This report has met two objectives: 1. The state's existing intercity rail corridors have been evaluated for potential upgrading in terms of estimated costs, travel times, and population projections. 2. The most promising existing rail and "new-corridor" alternatives for high-speed service...

It seems that transportation planners everywhere are looking for ways of reducing vehicle miles of travel (VMT) by automobile, even as citizens seem determined to drive more. The trend may be especially evident here in California where everyone seems to believe that use of cars is excessive,...

In recent years, the topic of "Suburban Gridlock" has emerged as one of the most significant transportation problems in the United States (Cervero, 1985). As population deconcentrates from central cities to suburban rings, and increasingly to the peripheries of those rings, employment has tended...

Nonparametric estimation of a density from contaminated data is a difficult problem, for which convergence rates are notoriously slow. We introduce parametrically assisted nonparametric estimators which can dramatically improve on the performance of standard nonparametric estimators when the...

We consider classification of functional data when the training curves are not observed on the same interval. Different types of classifier are suggested, one of which involves a new curve extension procedure. Our approach enables us to exploit the information contained in the endpoints of these...

This paper explores the attitudes and practices of property developers and related agents in facilitating or constraining disabled people's access in the built environment. While acknowledging that the development process is characterised by a range of socio-institutional structures and...
