<title>A<sc>bstract</sc> </title> This paper develops alternatively structured trip frequency/generation models, and investigates their forecast performance. The first model presented is the simple linear model with a discussion of its theoretical shortcomings. Models that address, in a progressive fashion, the...

<title>A<sc>bstract</sc> </title> Highway and transportation agencies implement large-scale traffic monitoring programs to fulfill the planning, operation and management needs of highway systems. These monitoring programs typically use inductive loops as detectors to collect traffic data. Because of the harsh...

<title>A<sc>bstract</sc> </title> This paper investigates route choice behaviour on freeways between Taipei and Taichung in Taiwan under the provision of real-time traffic information. Two types of route choice selection rules (the best-route and habitual-route) are analysed using ordered probit models to identify the...

<title>A<sc>bstract</sc> </title> The ability to judge and select a model that is appropriate for a particular application is considered to be one of the most important aspects in contemporary transport planning. However, there is no suitable procedure for the systematic selection of a model that is most appropriate...

<title>A<sc>bstract</sc> </title> This paper proposes a method for estimating transportation supply requirements when the suppressed demand of the transportation disadvantaged (TD) can be calculated and added to existing demand for travel. The underlying assumption is that the travel conditions of these TD groups must...

<title>A<sc>bstract</sc> </title> Intermodal freight transport has received increased attention due to problems of road congestion, environmental concerns and traffic safety. A growing recognition of the strategic importance of speed and agility in the supply chain is forcing firms to reconsider traditional logistic...

<title>A<sc>bstract</sc> </title> Understanding work zone traffic behavior is important for the planning and operation of work zones. The objective of this paper is to develop a mathematical model of work zone traffic flow elements by analyzing the relationships between speed, flow, and density that can be used to...

<title>A<sc>bstract</sc> </title> Notwithstanding the extensive research that exists on the strength of the relationship between land use and travel behavior, a consensus has not yet been reached. One possible explanation may be the existence of a wide range of influencing variables. Previous research assumed that the...

<title>A<sc>bstract</sc> </title> In the United States, most airports do not place any limitations on airline schedules. At a few major airports, the current scheduling restrictions (mostly administrative measures) have not been sufficiently strict to avoid consistent delays and have raised debates about both the...

<title>A<sc>bstract</sc> </title> This study analyzes aggregate consumer expenditure data from the US between 1984 and 2002, to determine relationships between expenditures on transportation and communications. We first identified 15 categories of goods -- nine for transportation, five for communications, and one for...
