Earth Worm Algorithm: a complete vehicle-infrastructure-driver model
Relevant road risk evaluation is required to build safe road and to adopt adequate maintenance strategy. One of the most crucial point for this evaluation is to determine the limits of control for given vehicles on a studied road. These limits have to be known for ensuring safe range of using conditions and acceptable safety margins. They are usual...
Evaluation probabiliste de la dangerosité des trajectoires de véhicules en virages
Situé dans le contexte général de la sécurité routière, et plus particulièrement axé sur la sécurité des véhicules légers (VL) en virages, ce travail de thèse a pour objet de proposer une méthodologie fiabiliste de prédiction de trajectoires à risque, basée sur le traitement statistique et la modélisation probabiliste de trajectoires réelles de VL ...

Real-time bus route state forecasting using particle filter and mesoscopic modeling
In the absence of system control strategies, it is common to observe bus bunching in transit operations. A transit operator would benefit from an accurate forecast of bus operations in order to control the system before it becomes too disrupted to be restored to a stable condition. To accomplish this, we present a general bus prediction framework. ...

Switched LQR/H steering vehicle control to detect critical driving situations
This paper proposes a switching steering vehicle control designed using the linear quadratic regulator (LQR) problem, the Linear Matrix Inequality (LMI) framework and the H norm. The proposed switched control law comprises two levels: the first level is a switched Proportional-Integral-Derivative controller of lateral deviation (PIDy) and the secon...
Stochastic analysis of trajectories of vehicles in bends: Estimation of probability of failure
In spite of considerable improvement of road safety these last years, the level of the accidentology is always worrisome in France in 2010. A better management of the difficulties in bend would allow to avoid 15 percents of fatal accidents. In the research programme on infrastructures and road safety of the IFSTTAR, it was decided to investigate in...
Kinematic analysis of hand trajectory of seated upper arm reaching movements in a large workspace
Reaching and pointing on a target is a very common task in workplace design. The index trajectory for these movements can be used in inverse kinematics simulation processes as end-effecter. In most of published work, hand reaching movements were generally restricted to a small part of reachable space and the trunk was not involved in motion (see a ...
