Describing the relationship between vehicle volume and travel time delay on road sections consisting multiple intersections in the context of junction quantity is favorable to extend the advantage of intersection-specific volume-delay functions. This paper demonstrates a microsimulation method combined with a non-linear function fitting algorithm to determine unbiased delay function parameters ...

In traditional traffic assignment procedure, each traffic analysis zone is represented by one point in its geometric center which is connected to the network by several connectors. Results of studies show that different connector patterns would result up to 10% change in estimated volume and up to 20% change in total travel time. Also the different patterns of connectors can change the priority...

16. Abstract Research on travel-demand modeling has predominantly focused on weekday activity-travel patterns, with the study of the effects of commute travel on peak period traffic congestion as a major objective. In contrast, there have been few studies examining the weekend activity-travel behavior of individuals. However, weekend travel volume has been increasing over time and is comparable...

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...

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...
