Mitigating network congestion

Carolina Osorio Pizano

Congestion is a phenomenon that arises in a variety of contexts. The most familiar representation is urban traffic congestion. Nonetheless, phenomenons such as prison cell congestion, hospital bed blocking or, at a cellular scale, ribosome congestion, also ...

Improving matrix estimation pertaining to detailed traffic information and sophisticated traffic state

Technical innovation and extensive application of adaptive signal control at intersections have made turning flow information that provide more precise constraints for Origin-Destination matrix (O-D matrix) estimation easily available in great quantity and ...

Methodology for traffic risks identification

André-Gilles Dumont, Edward Chung, Minh Hai Pham

Of all modes of transport, transport by road is the most dangerous and the most costly in terms of human lives, according to Road Safety Action Program (2003-2010). In Europe, the 2010 road safety target of halving the number of road fatalities by 2010 see ...

ANALYZING AND COMPARING TRAFFIC NETWORK CONDITIONS WITH A QUALITY TOOL BASED ON FLOATING CAR AND STATIONARY DATA

Cities with medium to high traffic volumes are expected to keep the traffic rolling in a most efficient way. Accidents, construction sites or large events are counteracting this effort. In addition, cities are facing the fact that traffic signal plans conf ...

Effects of Variable Speed Limits on Motorway Traffic Flow

Variable speed limits (VSLs) displayed on roadside variable message signs (VMSs) have emerged as a widespread traffic control measure on motorways in many countries, leading to substantial traffic safety benefits; however, there is no clear evidence of imp ...

Fast exclusion of errant devices from vehicular networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya

Vehicular networks, in which cars communicate wirelessly to exchange information on traffic conditions, offer a promising way to improve road safety. Yet ensuring the correct functioning of such a system is essential: malicious or faulty devices transmitti ...

Applicability of road safety indicators to assess driving risks under Swiss road conditions

André-Gilles Dumont, Edward Chung, Minh Hai Pham

Road traffic crash is a problem in every country. According to World Health Organization, in Europe there are about 127,000 people killed and at least some 2.4 million injured each year. Incident detection algorithms to detect incidents on motorways are we ...

SEVECOM - Secure Vehicle Communication

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya, Levente Buttyan

Vehicle to Vehicle communication (V2V) and Vehicle to Infrastructure communication (V2I) promise to improve road safety and optimize road traffic through cooperative systems applications. A prerequisite for the successful deployment of vehicular communicat ...

Modeling Internet backbone traffic at the flow level

Patrick Thiran

Our goal is to design a traffic model for non congested IP backbone links, which is simple enough to be used in network operation, while being as general as possible. The proposed solution is to model the traffic at the flow level by a Poisson shot-noise p ...

Route choice calibration in urban context

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 ...
