Contraflow operation is frequently used for reducing traffic congestion near tunnels and bridges where traffic demands from the opposite directions vary periodically. In this work, a generic real-time optimal contraflow control method has been introduced. The introduced method integrates two important functional components: 1) an intelligent system with artificial neural network and fuzzy patte...

This research presents and explores a stochastic model to predict traffic flow along a highway and provides a framework to investigate some potential applications, including dynamic congestion pricing. Traffic congestion in urban areas is posing many challenges, and a traffic flow model that accurately predicts traffic conditions can be useful in responding to them. Traditionally, deterministic...

The unreliable network layer in the Internet has been a cause of concern for network managers and users. The unreliability manifests itself in terms of lost or delayed packets due to congestion or failure in the network. One of the causes of congestion is the inherent burstiness of network traffic. Traffic includes unpredictable large file or web page transfers as well as variable rate media st...

This study investigates the causes, effects and remedies of traffic congestion which has become a common sight in most highways in Nigeria; Mowe/Ibafo section of the Lagos-Ibadan expressway was used as the case-study. 300 Structured questionnaires were distributed among the road users comprising drivers (Private and Commercial), passengers, pedestrians, traffic officers, church congregations, c...

Mobile ad hoc network congestion control is a significant problem. Standard mechanism for congestion control (TCP), the ability to run certain features of a wireless network, several mutations are not common. In particular, the enormous changes in the network topology and the joint nature of the wireless network. It also creates significant challenges in mobile ad hoc networks (MANET), density ...

Traffic congestion is a situation on road networks that occurs as road use increases. When traffic demand increase, the interaction between vehicles slows the speed of the traffic stream and congestion occurs. As demand approaches the capacity of a road, extreme traffic congestion sets in. Current techniques for road-traffic monitoring rely on sensors which have limited capabilities, inflexibil...

For many power-limited networks, such as wireless sensor networks and mobile ad hoc networks, maximizing the network lifetime is the first concern in the related designing and maintaining activities. We study the network lifetime from the perspective of network science. In our dynamic network, nodes are assigned a fixed amount of energy initially and consume the energy in the delivery of packet...

Several techniques have been developed to meet the demand for faster and more efficient access to the Internet. Different applications have different networking requirements. For example, realtime interactive voice requires a low latency network path, but does not require high bandwidth. QoS refers to the ability of a network to provide improved service to selected network traffic over various ...

As the major problem of urban and developed cities is spreading of traffic congestion day by day. For which, there is a pressing need of advanced technology to provide reliable results with improvement of the state of the art of traffic control mechanism. As on date, Traffic problems are increasing with a higher rate around the world because of the number of vehicles are increasing by leaps and...

Despite extensive work on the network congestion[Jain, 1990], network congestion remains a real problem. The solution is not one answer, but many. Call admission controls try to limit the number of sessions according to the network’s traffic capacity. Implicit and explicit feedback congestion control techniques are often too slow in reacting to transient conditions. Window, automatic code gappi...
