Using two years of crash and average annual daily traffic data we examine the locations and conditions linked to truck-involved crashes (accidents). A binomial logit model is used to describe how the probability that a crash involves a truck is a function of the percentage of annual average...

A structural model is used to explain activity interactions between heads of households and, in so doing, to explain household demand for travel. The model attempts to capture links between activity participation and associated derived travel, links between activities performed by male and...

This paper documents an application of panel, or longitudinal data collection in the evaluation of a TSM (Transportation Systems Management) demonstration project. The project was a four-week demonstration of staggered work hours in downtown Honolulu during February--March 1988. The 4 wave panel...

The product of this research is a dynamic simultaneous equations model of car ownership and modal travel distances as a function of income. The data are from the Dutch National Mobility Panel (1984-1987); and four modes are encompassed: car driver, car passenger, trainl and bus-tram-subway. A...

This study explores the growth of electronic home shopping in terms of likely transportation and communication interactions. Although opportunities exist to shop from home today, most consumers initiate travel trips to stores or markets. Widespread use of automobiles has facilitated the...

In this paper a model is developed and estimated empirically of the allocation of time to out-ofhome activities and travel. The model has three important characteristics. First, the allocation of time to out of home activities by individuals is the key concept in the research reported here....

The vehicle choice model developed here is one component in a mlcro-slmulatlon demand forecasting system being designed to produce annual forecasts of new and used vehicle demand by vehicle type and geographic area in Cahforma. The system will also forecast annual vehicle miles traveled for all...

To better understand how road congestion adversely affects trucking operations in California, we surveyed approximately 1,200 managers of all types of trucking companies operating in California. More than 80% of these managers consider traffic congestion on freeways and surface streets to be...

This research is part of the project aimed at developing a model system to forecast demand for clean fuel vehicles in California, conducted by researchers at the University of California, Irvine and University of California, Davis. The objective of the research reported here is to explain annual...
