This paper analyzes a model of early morning traffic congestion, that is a special case of the model considered in Newell (1988). A fixed number of identical vehicles travel along a single-lane road of constant width from a common origin to a common destination, with LWR flow congestion and Greenshields’ Relation. Vehicles have a common work start time, late arrivals are not permitted, and trip...

In a network which does not differentiate among users, the equilibrium rate for any user is primarily decided by the congestion control being used. By changing their congestion control schemes, “uncooperative” users can gain more than their fair share of bandwidth, at the cost of cooperative users. We present a control-theoretic algorithm to counteract uncooperative users by adjusting the price...

En route airspace congestion, often due to convective weather, causes system-wide delays and disruption in the U.S. National Airspace System (NAS). Today’s methods for managing congestion are mostly manual, based on uncertain forecasts of weather and traffic demand, and often involve rerouting or delaying entire flows of aircraft. A new, incremental decision-making approach is proposed, in whic...

The congestion pricing is an efficient allocation approach to mediate demand and supply of network resources. Different from the previous pricing using Affine Marginal Cost (AMC), we focus on studying the game between network coding and routing flows sharing a single link when users are price anticipating based on an Average Cost Sharing (ACS) pricing mechanism. We characterize the worst-case e...

Road transportation networks are experiencing ever growing recurrent congestion and non-recurrent in developing China, which is a concurrent event. This paper takes Jingzang Expressway(G6) as an example, describes the saturation flow along the G6 compared with its designed capacity by the actual volume of each segment according to the density and structural characteristics of cars and trucks, a...

P2P traffic has brought serious impact on the bearer network, and how to utilize network bandwidth has become a common concern problem for the Internet Service Provider (ISP) and the P2P user. A congestion distance and DHT based P2P traffic optimization method is proposed in this paper. The P2P traffic optimization model imports both aims of the ISP and the P2P user, and the cost of congestion ...

Congestion leads to bandwidth degradation and, packet losses thereby causing retransmissions and higher energy drain rate by the nodes in Mobile Ad hoc Networks(MANET). So providing Quality of Service(QoS) and reducing congestion levels are some of the major issues to be addressed in these networks. However , use of appropriate congestion control measures is complicated due to the interdependen...

The Auckland region in New Zealand (NZ) accounts for a third of NZ’s population but only about 2% of NZ’s landmass. The relative dominance of the Auckland region of New Zealand is a rare instance of polarised population distribution that is paralleled only by a handful of other urban regions such as Athens in Greece and Buenos Aires in Argentina. (Athens has roughly 30% of Greece’s population o...

We formulate end-to-end congestion control as a global optimization problem. Based on this formulation, a class of minimum cost flow control (MCFC) algorithms for adjusting session rates or window sizes are proposed. Significantly, we show that these algorithms can be implemented at the transport layer of an IP network and can provide certain fairness properties and user priority options withou...
