In this paper we propose to use clustering methods for automatic counting of pedestrians in video sequences. As input, we consider the output of those detection/ tracking systems that overestimate the number of targets. Clustering techniques are applied to ...
We present behavioral models designed to capture the response of drivers to real-time traffic information. In 2003, we have conducted a survey in Switzerland in order to collect both Revealed Preferences (RP) and Stated Preferences (SP) about choice decisi ...
The paper presents principles which can be used in reference numerical models to make easy calculations for predicting long-range outdoor sound propagation under complex environment. Limits, assumptions as well as approximations used are discussed here in ...
The self-supplied navigation concept is based on the combination of the floating car data technique and the dynamic route guidance service in the same vehicles. The gains obtained by the users of such system are, obviously, closely related to the percentag ...
Microsimulation is increasingly being used for different types of traffic studies and particularly for assessment of ITS applications. This paper explains how a large urban network, the case of Lausanne, has been calibrated with the microsimulator AIMSUN, ...
Recent developments in technologies such as Automatic Vehicle Location (AVL) and advanced control systems have stimulated new interest in bus priority facilities using traffic signals. The use of AVL systems has generated opportunities for implementing fle ...
The purpose of this thesis is to show on explicit examples how various theoretical concepts, ranging from statistical mechanics to stochastic control and from traffic theory to queuing systems, can be transferred to transport processes, encountered in part ...
Cet article fournit une analyse du transport intermodal en Suisse. Il fait partie de la série d’expertises indépendantes effectuées pour l’Observatoire des Politiques et Stratégies de Transport en Europe. La principale composante du trafic intermodal en Su ...
The bus priority strategies at traffic signals for Transport for London (TfL) was investigated. It was shown that new automatic vehicle location (AVL) technologies are providing more sophisticated forms of priority, where bus specific levels of priority ca ...
In this work we present a novel concept of augmenting a search tree in a packet-processing system with an dditional data structure, a Network of Shortcuts, in order to adapt the search to current input traffic patterns and significantly speed-up the freque ...
