Dynamic traffic assignment models have been attracting increasing attention with the progress of traffic management policies based on information technology. These dynamic estimation tools, however, just apply static route choice models either at only origin node or at every arrival node. This paper aims at providing some knowledge on drivers’ dynamic route choice behavior using probe-vehicle d...

Abstract. This paper presents the development and evaluation of a dynamic subchannel allocation scheme for downlink multi-cellular Orthogonal Frequency Division Multiple Access (OFDMA) systems. In the considered system each Access Point (AP) and the associated Mobile Terminals (MTs) are not operating on a frequency channel with a fixed bandwidth, rather the channel bandwidth for each AP is dyna...

In this work, distributed dynamic channel assignment strategies with violation to the reuse pattern using vehicular mobility information for highway microcellular environments are proposed. It is shown that, when vehicular mobility information is included in the acquisition channel policy, the outage probability degradation because of the use of channels with one violation to the reuse pattern ...

In cellular communication systems, directional multibeam antennas at cell sites can be used to reduce co-channel interference, increase frequency reuse and improve system capacity. When combined with dynamic channel assignment (DCA), additional improvement is possible. We propose a multibeam scheme using dynamic channel assignment across multiple sectors. A cell is divided into several sectors,...

The paper reports on the algorithmic treatment and computer implementation of a macroscopic dynamic traffic assignment model called LADTA. The modelling assumptions and the mathematical analysis founding the model are first stated. Detailed descriptions of the main algorithms are given, together with the principles of the computer implementation. It is shown how the design of the software archi...
