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...

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...

The issue of shared use urban freight facilities first received attention during the 1970's when it was observed that, while inter-urban freight movements were becoming increasingly efficient, there were significant diseconomies in the movement of freight via truck within urban areas. Early...

Efficient maritime transportation is heavily dependent on the smooth operation of land transportation. Swift modal transfers are key to successful intermodal operations. In this paper we examine the efficiency of maritime intermodal transfer facilities in California, from the point of view of...

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...

More than 80% of these managers consider traffic congestion on freeways and surface streets to be either a "somewhat...

Freight transportation plays a vital role in the economy of the nation and of the state of California in particular. The value of total freight shipments originating in California in 1997 is estimated at $638.5 billion, 10.6 percent of all US shipments by value.1 This represents 706.5 million...

Modern panel surveys frequently suffer from high and likely non-ignorable attrition, and transportation surveys suffer from poor travel time estimates. This paper examines new methods for adjusting forecasts and model estimates to account for these problems. The methods we describe are...
