The impressive movement forward of transportation modeling and simulation emerges from three related but distinct sources. The first source is a fundamental change in planning practice that one could name dynamic planning practice to indicate the existence of bi-directional time (from the past...

The substantial reductions in motor vehicle emissions that have occurred since the late 1960s have been accompanied by continuous increases in vehicle emission control costs, and cost increases or decreases due to changes in vehicle performance such as driveability, power, fuel economy, and...

Big universities are like small cities. They contain athletic facilities, concert halls, housing, hospitals, libraries, museums, offices, parking, restaurants, stores, theaters, and, of course, classrooms. Big universities also face urban transportation problems, and a few of them have pioneered...

Transportation control measures are often implemented for their environmental benefits, but there is a need to quantify what benefits actually occur. Telecommuting has the potential to reduce the number of daily trips and miles traveled with personal vehicles and, consequently, the overall...

Local area freight networks (LANs) are used to collect and distribute freight within metropolitan regions. Focusing on common carriers, this paper classifies LAN topologies, then shows how the optimal topology depends on demand characteristics. Continuous space approximations are used to analyze...

If truck drivers could use internet-enabled wireless devices to access traveler information, what type of information would they most want to have? The answer almost surely varies according to the type of trucking operation, location, and many other factors. We analyzed preferences for traveler...

High octane gasolines, including “premium†and midgrade, steadily gained market share in the United States during the 1980s, increasing from 12% of the total gasoline market in 1983 to 15% in 1985 and 30% in 1989. This 18% increase in market share represents an aggregate revenue...
