Equilibration of travel demand and system performance has traditionally been considered an important problem, primarily for auto travel, and only secondarily for bus travel. Initially, "capacity-constrained traffic assignments" were predominant. These algorithms were invariably restricted to auto mode, provided no information on convergence, and suffered from other shortcomings (Ruiter, 1973). ...

Using road GIS (geographical information systems) data and travel demand data for two U.S. urban areas, the dynamical driver sources of each road segment were located. A method to target road clusters closely related to urban traffic congestion was then developed to improve road network efficiency. The targeted road clusters show different spatial distributions at different times of a day, indi...

In this paper, we are interested in routing vehicles to minimize unmet demand under uncertainty. Such a problem arises in situations with large demand or tight deadlines, so that routes that satisfy all demand points are difficult or impossible to obtain. An important application is the distribution of medical supplies to respond to large-scale emergencies, such as natural disasters or terroris...

Understanding the public transportation users’ preferences to long-distance travel modes would contribute to reasonable developing policies and resource allocation. This paper aims to explore the influencing mechanism of potential factors on the long-distance travel mode choice. A survey was conducted to collect the data. The analysis of variance (ANOVA) approach was applied to analyze the corr...

In this paper, we are interested in routing vehicles to minimize unmet demand with uncertain demand and travel time parameters. Such a problem arises in situations with large demand or tight deadlines, so that routes that satisfy all demand points are difficult or impossible to obtain. An important application is the distribution of medical supplies to respond to large-scale emergencies, such a...

When modelling travel times and traffic flows varying over time on traffic networks it is desirable that the travel times should satisfy certain properties. This paper investigates these properties and their interrelationships, in particular, uniqueness and continuity, first-in-first-out (FIFO), causality and time-flow consistency, while assuming a single traffic type. For generality we investi...
