In this paper the factors having influence on travel demand to Iran are paper explored. The hypothesis of the research specifies the variable of “domestic upheavals and insecurity” as the most significant obstacle to 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 tourism in different countries, ar...

High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a v...

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...

T c = congested link travel time (seconds) T f = free-flow link travel time (seconds) v = link traffic volume (vehicles) c = link capacity (vehicles) α, β = volume/delay coefficients S r c = regular vehicle congested link travel speed (feet/hour) S e c = emergency vehicle congested link travel speed (feet/hour) S f = free-flow link travel speed (feet/hour) u = utilization of road segment in Are...

We develop a control method for traffic networks that uses information providing as a control measure. The provided information consists of travel time information of different possible routes, shown on variable message signs. We will present a model that describes the change in turning rates due to a travel time difference between two possible routes. The controller we develop integrates the p...
