Existing frequency assignment efforts in wireless sensor network research focus on balancing available physical frequencies among neighboring nodes, without paying attention to the fact that different nodes have different traffic volumes. Ignoring the different traffic requirements in different nodes in frequency assignment design leads to poor MAC performance. Therefore, in this paper, we are ...

Congestion in urban arterial road networks increases steadily. For long-range road investment planning it is essential to be able to evaluate the impacts of this congestion on road user costs and on the environment. The current method is to use transport planning models with static traffic assignment. This method, however, may significantly underestimate the impacts of congestion because of the...

Traffic crashes and other emergencies have impacts on traffic operations in transportation networks, often resulting in non-recurring congestion. Congestion, in turn, may impede the ability of Emergency Medical Services (EMS) to provide timely response to those in need of medical attention. The work in this paper investigated the impact of incidents of varying severity and duration on transport...

This paper focuses on two aspects of photonic network traffic performance investigation. Two different modelling approaches for the evaluation of network nodes under dynamic traffic conditions are described. This allows to evaluate how suitable different node architectures are for networks carrying dynamic traffic. Furthermore, routing strategies are becoming more important with increasing dyna...

Traffic Assignment Problem (TAP) is a critical issue for transportation and mobility models that deals mainly with the calculus delivery of best-cost routes trips in traffic network. It computationally complex problem focused on finding user equilibrium (UE) system optimum (SO). The Weighted Multi-Maps (TWM) technique offers new perspective TAP calculus, based routing decisions using different ...
