The paper presents the design approach, the objectives, the development, the advantages, and some application results of the traffic-responsive urban control (TUC) strategy. Based on a store-and-forward modelling of the urban network traffic and using the ...
Interoperability has become a keyword in the European Transport Policy, with the strong objective to improve transportation services. In the rail sector, this trend is embodied in technological innovations: A deep change in the communication and signalling ...
From a practical point of view, the calibration of micro-simulation route choice parameters is a complex work. It is mainly the case in urban networks where the link travel time variability due to traffic lights and the high number of path possibilities ma ...
Freight traffic through the Alps is growing significantly. Road transport, which is better adapted to the new requirements of production and distribution system, resulted in increased pollution, congestion, and safety concerns. The advent of the concept of ...
We consider increase-decrease congestion controls, a formulation that accommodates many known congestion controls. There have been many works that aim to obtain relation between the loss-event rate \fpp and time-average window \taw for some known parti ...
Undertaken in the field of design methods for flexible pavement, the present study focuses on the introduction of traffic loads, applied mainly to mechanistic empirical methods. In such research, strains due to traffic loads — calculated by pavement modeli ...
In this paper, we introduce a framework to estimate the power consumption on switch fabrics in network routers. We propose different modeling methodologies for node switches, internal buffers and interconnect wires inside switch fabric architectures. A sim ...
Current TCP-friendly congestion control mechanisms such as those used in TFRC adjust the packet rate in order to adapt to network conditions and obtain a throughput not exceeding that of a TCP connection operating under the same conditions. In an environme ...
The laboratory of traffic facilities (LAVOC) is working in the fields of design, operation and maintenance of transport infrastructures. Since 1998 the LAVOC proposes an ITS course about the concepts and the methods of the transport telematics in order to ...
This article describes how a simulation-based evaluation methodology was applied on a variable speed limit signs (VSLS) system designed for a heavily-traveled roadway around Lausanne, Switzerland. Using the MITSIM Laboratory, the evaluation focused on dete ...
