Route choice analysis

Emma Frejinger

This thesis focuses on the route choice behavior of car drivers (uni-modal networks). More precisely, we are interested in identifying which route a given traveler would take to go from one location to another. For the analysis of this problem we use discr ...

Mesoscopic simulator data to perform dynamic origin- destination matrices estimation in urban context

André-Gilles Dumont, Edward Chung, Emmanuel Bert

The aim of this paper is to explore a new approach to obtain better traffic demand (Origin-Destination, OD matrices) for dense urban networks using traffic simulation data. From reviewing existing methods, from static to dynamic OD matrix evaluation, possi ...

A misapplication of the local ramp metering strategy ALINEA

In a recent series of articles with largely identical contents and results, some claims are raised about the pertinence and performance of the well-known and widely field-applied local ramp metering algorithm ALINEA and of some extended versions thereof. T ...

Approach for Dynamic Origin-Destination Matrices Estimation in Urban Context

André-Gilles Dumont, Edward Chung, Emmanuel Bert

The aim of this paper is to explore a new approach to obtain better traffic demand (Origin-Destination, OD matrices) in dense urban networks. From reviewing actual methods, for static and dynamic OD matrix evaluation, possible deficiencies in the approach ...

A Two-Layered Anomaly Detection Technique Based on Multi-modal Flow Behavior Models

Jean-Yves Le Boudec

We present a novel technique to detect traffic anomalies based on network flow behavior in different traffic features. Based on the observation that a network has multiple behavior modes, we estimate the modes in each feature component and extract their mo ...

Event traffic forecast for metropolitan areas based on microscopic simulation

It is shown that a traditional travel demand forecast combined with a simulationbased approach can serve as a short-term forecast for the traffic situation. The approach presented was developed and tested during the Soccer World Cup 2006 in the city of Col ...

Long-term Investigations of Quality and Reliability of the Video Image Detection System m3

Video image detection systems (VIDS) are increasingly being used to monitor the traffic situation. Visual systems are operated with the help of image processing, which has aroused a permanent discussion concerning the quality of such systems. Therefore, di ...

Motorway traffic surveillance and control

The available capacity of motorway networks is degraded in presence of traffic congestion, leading to reduced throughput, increased pollution and higher accident risk. The traffic flow efficiency may be increased via suitable application of several control ...
