Travel time reliability has generally been surmised to be an important attribute of transportation systems. In this paper, we study the contribution of travel time reliability in travelers’ route choice decisions. Traveler’s route choice is formulated as a mixed-logit model, with the coefficients in the model representing individual traveler’s preferences or tastes towards travel time, reliabil...

We study road supply by competing firms between a single origin and destination. In previous studies, firms simultaneously set their tolls and capacities while taking the actions of the others as given in a Nash fashion. Then, under some widely used technical assumptions, firms set a volume/capacity ratio that is socially optimal, and thus the level of travel time or service quality is socially...

Due to population growth in urban areas, especially in the capital cities in developing countries, the use of private vehicles are increasing, leading to many problems such as congestion, pollution, noise, long travel time, high travel cost and more side effects. In such circumstances government policy would encourage people to use public transportation. In the meantime, employing the Intellige...

Prediction of travel times is a vital function of many advanced traveler information systems. In this study, an experimental analysis of the relationship between instantaneous travel time and real travel time is carried out and a method to predict freeway travel times using a linear model is proposed. The proposed method is applied to a data set of the Hanshin Expressway. The implementation pro...

CONTEXT Minimum procedure volume thresholds have been proposed to improve outcomes among patients undergoing percutaneous transluminal coronary angioplasty (PTCA). How regionalization policies would affect patient travel distances is not known. OBJECTIVE To examine the effect of regionalization of PTCA on patient travel distances. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort stu...

A consumer makes travel distance judgment to determine the place to visit. Stores that gain favorable travel distance judgment could gain access to a large volume of customer base. Travel distance judgment is often made with the aid of technologies, such as the mobile location-based service (LBS). In the present research-in-progress, we build on the human’s environmental distance information co...

this article aims at identifying the factors involved in affecting the travel demand to iran. the hypothesis of the research specifies the variable of “domestic social unrest and insecurity” as the most significant obstacle that stands against an expansion of the demand for travel to iran. to test the above hypothesis, first several demand models that have been proposed to study demand for tour...

This paper presents the various transportation application problems where travel time is an important variable and a factor. The paper demonstrates the limitation of the flow based travel time functions. The paper presents a density based travel time function. Following this, the paper develops a fundamental theory of travel time dynamics that is built from a given fundamental traffic relations...
