Traffic assignment is fundamentally a tool for transportation planning. It allocates trips within the traffic network. However, modern uses of traffic assignment also include shorter time horizons and even real-time use (e.g., for route recommendation). In the latter case, it is interesting to recommend routes that are as close as possible to the system optimum. To compute an approximation of t...

Campus and enterprise wireless networks are increasingly characterized by ubiquitous coverage and high traffic demands. An efficient channel assignment of access points (APs) in these networks has the potential to greatly improve wireless LAN performance. Therefore, previous studies have investigated methods for determining effective channel assignments. Existing approaches, however, do not ada...

Traditionally, the coordination of multiple traffic signals and the traffic assignment problem in an urban street network are considered as two separate optimization problems. However, it is easy to see that the traffic assignment has an influence on the optimal signal coordination and, vice versa, a change in the signal coordination changes the optimal traffic assignment. In this paper we pres...

This paper proposes a phase assignment algorithm “Silent Wave Algorithm (SWA)” for real-time MPEG traffic in ATM networks. Our algorithm decides when a new MPEG source should begin to transmit based on its notification parameters and traffic measurement of ongoing connections. Simulation results show that it is hard to accommodate MPEG traffic effectively without any control of phase assignment...

The user equilibrium traffic assignment principle is very important in the traffic assignment problem. Mathematical programming models are designed to solve the user equilibrium problem in traditional algorithms. Recently, the Physarum shows the ability to address the user equilibrium and system optimization traffic assignment problems. However, the Physarum model are not efficient in real traf...

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 ...
