Effet des messages de sécurité routière sur la détection des cyclistes par les automobilistes dans un environnement dynamique : implication des proce…

2018

The aim of the present project is to provide a better understanding of how safety messages can control drivers' vulnerable road user detection abilities. Safety messages provide both vulnerability information and elicit emotion with persons that are exposed to it. This thesis deals with how vulnerability information and emotions respectively affect vulnerable road user detection performances. A special focus was placed on cyclists because of the lack of studies that address cyclist detetcion issues. The project also focused on physiology, especially emotion identification through physiological patterns.

Relationship between cognitive and driving self-assessments in older drivers. Result of epidemiological and experimental on-road studies in france

2015

TRANSED 2015 - 14th International Conference on Mobility and Transport for Elderly and Disabled Persons, LISBONNE, PORTUGAL, 28-/07/2015 - 31/07/2015; Most older drivers are able to efficiently self-regulate their own driving practices, that means reducing driving exposure and avoiding the most challenging driving conditions such as driving at night or in poor weather or at complex intersections. We hypothesized that this self-regulation might exist only if older drivers have accurate insight into their own age-related functional and cognitive decline. This study aims to evaluate how well self-estimation of cognitive ability of older corresponds to their actual driving performance, as asses…

Study of control command of dynamic platform for driving simulation and influence on simulator sickness

2013

Simulation has been intensively involved nowadays in research and development for automotive industry. Driving simulators are one of those simulation techniques which are used to evaluate the prototypes for the vehicle dynamics and driving assistance systems. However with the driving simulator, there is a lock associated with its use. Because representing a permanent scenario as scale 1 is quite difficult. Because of that difficulty, motion/simulator sickness is an inevitably important topic to study.This thesis proposes to explore methods and tools to implement in static or dynamic simulators. In this implementation, studies of simulator sickness are conducted with objective measures (via …

Prediction of hydraulic and acoustic properties of open-graded mixes

2014

The use of open-graded mixes increases significantly the hydraulic permeability of pavement and contributes to reduce the noise impact in comparison to traditional pavement. Such characteristics are very appealing and would greatly increase driver's safety. However, during service life, the pores tend to be clogged by many factors among them secondary traffic compaction and filling of voids by fine materials are relevant, especially on heavy routes. In this case the noise reduction and drainage capabilities will gradually disappear, causing serious problems for road safety and maintenance. In this paper we propose a simulation approach in order to predict the drainage and acoustic behavior …

Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction

2012

Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…

Attitude Function as a Moderator in Values-Attitudes-Behavior Relations

2011

Abstract The aim of the present study was to find whether attitude functions could be useful in predicting aberrant driving. One of the attitudes functions is to express values; hence, we hypothesized that attitudes whose function is to express values will better predict traffic violations. We explored: (i) values in relation to attitudes towards aberrant driving behavior by regression analysis; (ii) and we explored moderating role of attitude functions in value-attitude-behavior relations. The study sample included 305 respondents who completed self-report questionnaires. Current research confirms previous results and also shows that values do predict attitudes when individual had formed h…

Assessment Of Driving Stress Through SVM And KNN Classifiers On Multi-Domain Physiological Data

2022

We propose an objective stress assessment method based on the extraction of features from physiological time series and their classification using Support Vector Machine and K-Nearest Neighbors algorithms. For this purpose, we used an open dataset consisting of multiparametric physiological signals (electrocardiogram, electromyogram, galvanic skin response and breath signal) obtained during the execution of a driving route within the city of Boston with restful, highway and city driving periods indicative of three different stress states. To predict the driver stress level, 21 features were extracted from 122 chunks of raw signals and were subsequently managed by classification algorithms. …

A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness

2018

The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…

Multi-Control Virtual Reality Driving Simulator

2019

Immersive technologies (virtual and augmented reality) started gaining a lot of ground over the past few years initially in the video game industry, followed by simulators and finally integrated into many other classic applications. This paper aims to analyze how users respond to using new controlling devices in a scene designed as a driving simulator (race car track). The landscape and the controls are specifically tailored for interactions within immersive environments. In order to understand the capabilities of the experimental application and evaluate the new controls, several tests were conducted. The results are presented from a user experience perspective, emphasizing qualities, side…
