Towards real-time detection of cognitive effort in driving: Contribution of cardiac measurement
2016
En 2013, on estime que 40 à 50% des accidents corporels seraient dus à des défauts d'attention de la part du conducteur. Des études récentes ont mis en évidence la possibilité de détecter des états attentionnels dégradés afin de pouvoir mieux assister le conducteur ; ce thème de recherche représente donc un nouveau gisement de sécurité routière. Cette étude se concentre sur la détection de l'effort cognitif fournit par les conducteurs et cherche, par l'étude de la variation du rythme cardiaque, à identifier un indicateur d'effort sensible sur de courtes fenêtres temporelles.Chacun des 18 participants a passé 8 conditions expérimentales sur simulateur de conduite : la moitié où seule une tâc…
Miega problēmu saistība ar autovadīšanas kvalitāti
2021
Konkrētā pētījuma mērķis bija noskaidrot vai starp miega problēmām un autovadīšanas kvalitāti pastāv nozīmīgas saistības, kā arī kādi varētu būt autovadīšanas uzvedības un attieksmes prognozētāji. Datu analīzē tika izmantoti 94 respondentu dati vecumā no 19 līdz 75 (M=36, SD=13). Respondenti aizpildīja Aiovas miega traucējumu, Autovadītāju uzvedības un Attieksmes pret pārgalvīgu braukšanu aptaujas. Tika secināts, ka gurdums ir pozitīvi nozīmīgi saistīts ar pārkāpumiem, bīstamām kļūdām un nejaušības kļūdām, kā arī attieksmi pret pārkāpumiem. Gurdums nozīmīgi prognozēja attieksmi pret pārkāpumiem. Attieksme pret pārkāpumiem un izdevību izmantošanu, kā arī vecums nozīmīgi prognozēja pārkāpumus…
Epidemiology, Physiology and Clinical Approach to Sleepiness at the Wheel in OSA Patients: A Narrative Review
2022
Sleepiness at the wheel (SW) is recognized as an important factor contributing to road traffic accidents, since up to 30 percent of fatal accidents have been attributed to SW. Sleepiness-related motor vehicle accidents may occur both from falling asleep while driving and from behavior impairment attributable to sleepiness. SW can be caused by various sleep disorders but also by behavioral factors such as sleep deprivation, shift work and non-restorative sleep, as well as chronic disease or the treatment with drugs that negatively affect the level of vigilance. An association between obstructive sleep apnea (OSA) and motor vehicle accidents has been found, with an increasing risk in OSA pati…
The parental bond, resistance to peer influence and risky driving in adolescence
2014
The present study examined the relations between gender, the parental bond, resistance to peer influence, and risky driving. In particular, the mediating role of resistance to peer pressure in the relationship between parental bond and risky driving was examined. The moderating role of gender on these associations was also investigated. The sample comprised 322 adolescents (136 males and 186 females), aged from 16 to 20 years, who were living in northern Italy. Path analysis results showed that the maternal bond only indirectly influenced adolescents’ risky driving, via resistance to peer influence. On the contrary, the paternal bond was neither directly nor indirectly associated with risky…
Are subjective outcomes a “missing link” between driving stress and risky driving behaviors of commuters? Assessing the case of a LMIC
2023
Despite the efforts made by different stakeholders, most of Low and Middle-Income Countries (LMICs) continue to systematically report very negative road safety outcomes. In fact, in countries like Colombia, the rate of deaths from traffic crashes has increased in recent years. One of the most affected collectives in this regard -and at the same time one of the least addressed in specialized literature- are driving commuters, which are commonly exposed to several types of threats and stressors configuring an “everyday risk” potentially impairing their health and safety. This study aimed to assess whether there exists an indirect path -mediated by subjective outcomes- linking driving stress a…
Cognitive Computing supported Medical Decision Support System for Patient’s Driving Assessment
2018
To smartly utilize a huge and constantly growing volume of data, improve productivity and increase competitiveness in various fields of life; human requires decision making support systems that efficiently process and analyze the data, and, as a result, significantly speed up the process. Similarly to all other areas of human life, healthcare domain also is lacking Artificial Intelligence (AI) based solution. A number of supervised and unsupervised Machine Learning and Data Mining techniques exist to help us to deal with structured data. However, in a real life, we pretty much deal with unstructured data that hides useful knowledge and valuable information inside human-readable plain texts,…

Use of driving simulators for advanced driver assistance Systems evaluation in emergency situations
2012
Introducing advanced driver assistance systems in cars has numerous consequences, particularly on drivers' behavior and their interaction with the vehicle. The expected safety benefits of assistance systems can thus be jeopardized. In order to assess the actual safety benefits, driving simulators offer a safe and cheap alternative. This doctoral work relies on experiments carried out on driving simulators with different assistance systems. A first experimental part focuses on longitudinal control assistance: we studied drivers' familiarization with a Forward Collision Warning system in critical situations. A second experimental part focuses on lateral control assistance: we studied drivers'…
T9+HUD: Physical Keypad and HUD can Improve Driving Performance while Typing and Driving
2016
We introduce T9+HUD, a text entry method designed to decrease visual distraction while driving and typing. T9+HUD combines a physical 3x4 keypad on the steering wheel with a head-up-display (HUD) for projecting output on the windshield. Previous work suggests this may be a visually less demanding way to type while driving than the popular case which requires shifts of visual attention away from the road. We present a prototype design and report first results from a controlled evaluation in a driving simulator. While driving, the T9+HUD text entry rate was equal compared to a dashboard-mounted touchscreen device, but it reduced lane deviations by 70%. Furthermore, there was no significant di…
Visual-manual in-car tasks decomposed: text entry and kinetic scrolling as the main sources of visual distraction
2013
Distraction effects of in-car tasks with a touch screen based navigation system user interface were studied in a driving simulator experiment with eye tracking. The focus was to examine which particular in-car task components visually distract drivers the most. The results indicate that all of the visual-manual in-car tasks led to increased levels of experienced demands and to lower driving speeds. The most significant finding was that text entry and kinetic scrolling of lists were the main sources of visual distraction whereas simple selection tasks with familiar target locations led to least severe distraction effects.
