Introduction
My research fields deal with both to perception modeling and to the interactions modeling of the road users (drivers, pedestrians). More specifically, I aim to develop computational models of autonomous agents, a.k.a. Non Player Character, in order to allow Virtual Reality studies participants to interact with theses virtual agents. My works contribute to the development and the use of the simulation tools and 3D-immersive platforms.

Article
In this paper, we present an improved collision avoidance algorithm conceived to deal with zero-speed pedestrians in a crowd. A zero-speed pedestrian is a pedestrian who stops for a short, undefined period to rest, use a phone, or communicate with others, and then resumes walking later. Zero-speed pedestrians can be encountered in places such as sh...
Article
The temporal dimension (how long the pedestrian has been in a situation) and the social influence from the neighbor’s behaviors are important factors in street crossing decisions. In this paper, we propose a preliminary agent-based model of the street crossing decisions at a pedestrian light without traffic based on three priors. First, a pedestria...
Conference Paper
Automated vehicle driving raises the challenge of producing vehicle behaviors similar to those produced by human drivers. Automated vehicles could then be accepted more easily. Among the many different behaviors to be simulated, one is particularly important from a road safety point of view: the interaction between automated vehicles and pedestrian...

Introduction Héritage d’un centre-ville historique ou résultat d’aménagements ne considérant que trop peu les déplacements piétonniers, les trottoirs étroits sont des lieux d’interactions fortes entre piétons. Ces interactions, nommées joutes urbaines, correspondent aux situations où deux piétons se croisent sur un trottoir étroit, obligeant l’un d...

In this paper, we propose a concept to allow asymmetrical pedestrian interactions in simulation, based on ORCA model (Optimal Reciprocal Collision Avoidance). To reach our goal, we redefined two parameters of the model: the Time Horizon (TH) for anticipation and the Shared Effort (SE) for collision avoidance. In the default parameters model, the TH...

The objective of this paper is the analysis of the state of the art in pedestrian simulation models and the identification of key issues for further research, with particular focus on the modelling of pedestrians and motorised traffic. A review and comparative assessment of pedestrian simulation models is carried out, including macroscopic models,...
Chapter
During the last decade, human behavior has been studied in various fields such as architectural design, prevention and traffic engineering. Pedestrian management requires the ability to predict the evolution of behavior in different situations, especially in terms of traffic flow analysis. Most prediction models lack experimental data to be validat...

Article
While collision avoidance has been the most active topic in pedestrian simulation, the modelling of other kinds of behaviours appears to be essential for better realism. Thus higher cognitive levels of perception and behaviour improve simulation quality. Furthermore, giving an agent the possibility to choose the nature of its interactions with the...
Chapter
The objective of this chapter is to provide an overview of traffic data collection that can and should be used for the calibration and validation of traffic simulation models. There are big differences in availability of data from different sources. Some types of data such as loop detector data are widely available and used. Some can be measured wi...
Chapter
Walking, the oldest means of transport and practiced used by everyone, represents the “heart of life itself” around which any other means of transport should be subordinately organized. It is necessary to detect, locate, identity, and eventually track pedestrians to understand how they interact with each other. This article concerns the detection o...
Chapter
This chapter presents the different embedded sensors on the road, the selected organization for the sensors' deployment, the communication network connecting these different points of measurement and the supervisor. The study of the vehicles' trajectories is the only valid way to reveal the drivers' behavior. All vehicles will be located on the tra...

We propose a model of the driver perception suited for microscopic, agent-based traffic simulations. The model includes both top-down and bottom-up perception, and takes into account the limited amount of perceptive resource which gain access to short-term memory. The driving task is split into sub-tasks, which can be activated in parallel (e.g. ca...

Conference Paper
In everyday life, we can see amazing choreographies of movements of crowds of pedestrians. Pedestrians run into and avoid each other but do not seem to consciously cooperate. In this paper, we track a crowd of pedestrians in a large covered and cluttered area to understand their social behavior. Additionally, we try to analyze the characteristics o...

While most of multi-agent navigation approaches consider interactions with several agents as a simple combination of individual interactions, we propose an approach based on perception with both microscopic and mesoscopic representations of the environment. Indeed we consider that, during its navigation task inside a pedestrian crowd, a pedestrian...
Article
Most of the work on pedestrian simulations places them in a homogeneous context (emergency evacuation, crossing streets, airport). They do not take into account the many interpedestrian interactions induced by a dynamical environment requiring a contextual adaptation, for instance a situation with a danger perceived. Indeed, to deviate from a dange...

To simulate pedestrian crowds, most of the current studies use the microscopic approach, in which the pedestrian is modeled as an individual entity. With the microscopic approach, the heterogeneity in the pedestrian population is mostly based on inter-individual difference in the agent model parameters, like speed, destination, etc. In fact, what c...

Our study focused on the lateral position of drivers in relation to risk on rural crest vertical curves, using a field site proposed by a local operator of the French road network (Conseil Général de Maine-et-Loire, 49). The final goal was to test one road treatment on this field site. The study consisted of three stages. The first, using driving s...
Conference Paper
Perception is often seen in multiagent systems and in robotics from a passive point of view. The sensors of the agent collect information on its environment ; however the potentially important number of percepts is not realistic and may decrease the agents efficiency. In this article, we introduce a contextual goal-oriented perception filtering. Be...

An emphasis on active modes of transportation, that is, walking and cycling, has recently been renewed amid concerns for the environment and public health. However, the focus of research and practice that these modes have traditionally received is secondary to that received by motorized modes. As a consequence, the data on pedestrians (in particula...

The road network includes in two kind of road sections: straight lanes, and road cross-ings. For road crossings, Mandiau et al. [1] proposed an algorithm derived from the game theory, where a driver decides at each time step to GO or to STOP depending on his evaluation of the relative priorities with the other players he selected in the "game". The...

The collective behaviours that emerge from models based on formal rules are limited, especially when the models are designed to replicate human behaviour which, sometimes, contradict these formal rules. Mandiau et al. [1] showed how the possibility for an agent not to respect the highway code, formal rule, led to a more realistic collective behavio...

Approximately 48% of all fatal collisions in Europe are classified as single-vehicle run-off-road or head-on collisions. These crashes relate to trajectory control (road departure) and represent a safety challenge. In France, single-vehicle run-off-road crashes represent 21% of all crashes and head-on collisions represent 11%. This study evaluated...

In France, about 800 pedestrians are killed and over 17,000 are injured each year. There is a prevalence of these data in urban areas where the traffic is denser and the interaction between drivers and pedestrians is more complex. This can be exemplified by considering the risk taken by a pedestrian situated at a crossroads and willing to cross. Th...
