Chattez avec Graph Search
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.
This paper presents a finite element analysis modeling of rutting. The behaviors of the asphalt concrete is described using an elasto-viscoplastic constitutive relation, while an elastoplastic constitutive relation is used for the lower layers. The model a ...
This Phase 2 Report demostrates that the technology available for long life semi-rigid pavements is not as developed as that for fully-flexible pavement types. Whereas the concept of long-life fully-flexible pavements has been adopted in some European pave ...
Actuellement, les analyses de sécurité des réseaux routiers sont essentiellement « réactives », s’efforçant de localiser des points noirs à partir de relevés d’accidents. La présente étude propose de mener des analyses de sécurité « actives » en déterminan ...
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 ...
It has been known for more than 150 years that action effects in bridges due to traffic action are higher than it has to be expected for purely static loads. In the design of road bridges, this difference is considered by multiplying static traffic loads w ...
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 ...
In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. These solicitations affect the bituminous layers that can quickly attain their permanent deformation limit resistance. This phenomenon can lead ...
In the field of ITS applications evaluation, micro- simulation is becoming more and more a useful and powerful tool. In the evaluation process, one of the most important steps is the safety analysis. For that purpose, classical micro- simulation outputs gi ...
At the present time, variable-message signs (VMS) and variable speed-limit signs are in frequent use for traffic control, especially along urban motorways. The Lausanne by-pass is partially equipped with these and should be fully equipped in the near futur ...
Pavement rutting not only decreases the road service life but also creates a danger for the security of road users. In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. It is well known that the in ...
