Static traffic assignment (STA) models have been widely utilized in the field of strategic transport planning. However, STA cannot fully represent dynamic road conditions and suffer from inaccurate during congestion. At same time, an increasing number installed sensors become important means detecting conditions. To address shortcomings models, we integrate multi-source sensor datasets propose ...

Shared autonomous vehicles could provide low-cost service to travelers and possibly replace the need for personal vehicles. Previous studies found that each SAV could service multiple travelers, thereby eliminating several personal vehicle trips, and strategies such as preemptive relocation or dynamic ride-sharing could further improve service. However, a major limitation of previous studies is...

Channel assignment in multi-channel multi-radio wireless mesh networks is a powerful management tool to exploit available resources efficiently. In this paper, we study the problem of dynamic channel assignment in the presence of traffic with QoS constraints to optimize network performance, which is measured in terms of demand acceptance rate. We propose an on-line on-demand dynamic algorithm f...

Traffic networks inherently exhibit several degrees of decomposition, both hierarchically and geographically, and traffic control has been, in practice, severely influenced by this decomposition. Anticipatory Traffic Control literature (Allsop, 1974), in its own, deals with the fact that user behavior can be, at least to some degree, predicted, and that an “optimal” controller should take this ...

In this paper, we address the wavelength assignment problem for light-tree protection under different traffic models. For static traffic, we formulate the problem mathematically and propose two new heuristics (tabu search and iterated hill-climber) to solve it. For dynamic traffic, in contrast to previous work, we analyze the traffic characteristics and propose a Low Cost First Serve (LCFS) str...

Dynamic channel assignment algorithms allow wireless nodes to switch channels when their traffic loads exceed certain thresholds. These thresholds represent estimations of their throughput capacities. Unfortunately, the threshold estimation may not be accurate due to co-channel interference (CCI) and adjacent-channel interference (ACI), especially with high traffic loads in dense networks. When...

There is great interest in developing pricing models for congestion relief. However, most of the work in the literature uses static transportation models for analysis. The benefits of accounting for traffic dynamics under congestion pricing are unclear. This research performs a systematic comparison of static traffic assignment with the VISTA model, a simulation-based dynamic traffic assignment...
