Logistics managers rely on increasingly sophisticated technologies to track demand and associated inventories, allowing rapid response to meet anticipated demand, avoid shortfalls while minimizing transportation and inventory carrying costs. This ability to respond gives rise to complex decision...

Methods developed to study passenger travel behaviour can be usefully applied in studying perceptions, preferences, and behaviour of important actors in freight transportation. Transportation planners throughout the world can benefit by gaining improved understanding of how trucking companies...

In this report, we extend our previous work within MOU 372 on modeling and longitudinal speed control design for heavy commercial vehicles equipped with variable compression braking mechanisms. Previously, we developed a detailed crankangle based simulation model for a six cylinder, 350 hp...

This report describes the development and experimental validation of a coordination scheme between friction and discretely variable compression brakes for a Class 8 Freightliner truck used as a development platform in the California PATH program. The coordination scheme that we developed...

The objective of this research is to understand the demand for information technology among trucking companies. A multivariate discrete choice model is estimated on data from a large-scale survey of the trucking industry in California. This model is designed to identify the influences of each of...

Travel, like many other aspects of daily life, is being transformed by the information technology revolution. Accessibility can no longer be measured only in terms of travel time, distance or generalized travel cost. Information technology gives people virtual accessibility to a rapidly growing...

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...
