Although land use planning and urban design are increasingly touted as powerful tools for influencing transportation behavior, only modest empirical evidence for this relationship exists. Here, the results from a two-day activity diary are combined with innovative GIS-based measures of urban form and land use pattern to statistically test potential influences on noncommute home-based mode choic...

This paper identifies factors that influence the demand for a black bass fishing trip taken in the Southeastern U.S. using a double hurdle negative binomial count data model. The probability of fishing for a black bass is estimated in the first stage and the trip frequency for fishing a black bass is estimated in the second stage given that the individual has a positive probability towards unde...

This paper proposed an algorithm to decrease the discrepancies between imputation and real GPS data. Based on the activity-travel pattern obtained using a Bayesian Belief Network model, the algorithm takes into account the consistency of the full activitytravel pattern within a day in the sense that the activity-travel sequence is represented in terms of a hierarchical set of tours, and the tra...

INTRODUCTION The sharpened Romberg test (SRT) is commonly used by diving and hyperbaric physicians as an indicator of neurological decompression illness (DCI). People who spend a prolonged time on a boat at sea experience impairment in their balance on returning to shore, a condition known as mal de debarquement ('sea legs'). This conditioning of the vestibular system to the rocking motion of a...
