Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In Switzerland, the calculation method of road traffic noise is specified in the Ordonnance sur la protection contre le bruit (OPB) (Noise Protection Ordonnance (NPO)). This method is mainly based on observations that were realized in the 80s, and that are ...
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 ...
This paper summarises the results from a questionnaire-based survey and follow-up discussions with traffic operations staff of various cities in the world. The questionnaire asked cities about their currently employed control systems as well as about their ...
During the last nine years, a couple of prototype ITS applications based on Floating Car Data (FCD) of taxi fleets have been developed at German Aerospace Center (DLR). A core application is a route guidance and monitoring system based on current and histo ...
This contribution reports about the design and development of an open and flexible framework called DLR Traffic Data Platform (TD-Platform) that is able to process most well known traffic data like (X)FCD, loop detector and traffic video data and fuse them ...
Fusing traffic data from a variety of traffic sensors into a coherent, consistent, and reliable picture of the prevailing traffic conditions (e.g. densities, speeds, flows) is a critical and challenging task in any off- or online traffic management or info ...
In urban network, detectors are generally used for signal control. If the data from detectors are also used for travel time estimation and fed back to the traffic management and information systems then it will be a significant contribution for managing ur ...
This paper describes DELPHI, a pilot version of a joint web decision support application for real time traffic situation and prognosis, information exchange and cooperation between the Traffic Management Center, Emergency Rescue Services, the Police and th ...
An efficient method to estimate queues at traffic lights is proposed. Using floating car data and providing flexible capabilities for data fusion, it yields high-quality estimates for the traffic states at traffic lights at quite realistic scenarios. ...
