I recent years there has been a growing concern over the congested conditions of our urban highway facilities. The continuing escalation of adverse driving conditions in major urban areas has generated a feeling of discontent among automobile owners and transportation planners alike. One major factor that has contributed to this feeling of dissatisfaction is the rapid pace with which many of th...

Information and communication technologies (ICT) are enjoying fast development which immediately translate into their market enhancements nowadays (1). ICT relaxes both space and time constraints while allowing instant information exchange. In terms of activity-based travel demand, ICT use might substitute, complement or modify individual activity-travel behavior at varying degrees. On the othe...

The regional travel demand models are generally macroscopic in nature and do not include traffic controls in the traffic assignment process. In travel demand models, the road capacities are kept fixed within the functional classification of roadways and free-flow-speeds are adjusted to accommodate the impacts of traffic controls and traffic operations. Part of the reason this approach is adopte...

One notable issue to deal with when capturing the individualism of travel behaviors is the gender difference. An extensive body of research has widely acknowledged that women and men exhibit quite different travel and activity patterns. For example, findings have suggested that women tend to invest more time to family-sustaining activities and that women make more family-sustaining trips yet fe...

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). ...
