Pełny tekst źródłaBased on a bibliography, the main concepts used to describe the drivers’ behavior and, in particular, the interactions between vehicles in a single lane traffic flow, are analysed and critically examined. Besides an ordering of knowledge on the subject, this analysis enables us to throw light upon certain aspects which were hardly or never examined before. The conclusions of the bibliographical analysis and the use of a car- following experiment data, lead to the development of a new point of view, of which the main aspects are: - the consideration of the followed vehicle's acceleration as stimulus-variable for the following driver instead of the relative velocity. - the introduction of an evolutive reaction time, linked to the drivers intention that is reflected in the result of his response. - the distinction of a static and a dynamic state of the car- following phenomenon. In the final model the followed drivers acceleration represents the dynamics of an evolution, to which the follower tries to adapt his behavior, while he also takes the static state of the movements into account, represented by the relative velocity and distance

Pełny tekst źródłaThis research aims at understanding social cognition and personality variables linked with different driving behaviours among drivers taking a course designed to raise awareness about the causes and consequences of road traffic accidents. We refer to the theory of planned behaviour by Ajzen (1991). We also add descriptive norms concerning family, anticipated regrets, social support and personality measures : impulsivity, time perspective and conscienciousness. 251 offenders aged from 18 to 77 have participated at the study. The results show that the behavioural beliefs (BB), descriptive norms (DN) and Past negative (PN) explain 47% of the committment of exceeding the speed limit less than 20 km/h. The BB, the DN and sensation seeking explain 20% of the committment of exceeding the speed limit by at least 30 km/h. The BB, the DN and urgency explain 26% of the frequency of close following. The BB, Present hedonistic and not to be with social support explain 44% of the commitment of risky driving. The BB, the normative beliefs (NB) and DN explain 42% of the frequency of not wearing the safety belt. A heavy marijuana consumption and BB (to feel able to drive after taking drugs) explain 43% of the commitment of Driving Under the influence (DUI) of marijuana. This same BB, coupled with a heavy drinking and NB explain 32% of the commitment of DUI of alcohol. To conclude, an effective prevention requires to implement action plans in 3 differents levels : the subject, the family, the society

Pełny tekst źródłaIn the context of traffic modeling, we need some improvements in order to allow to simulate the near accident situations. The most actual agent based traffic simulations tools focuse on the decision activity of drivers. However, the activity of perception is an important precondition of decision. We aim to propose new solutions for agent based modeling of human drivers perception. The proposition include a double activity of perception (passive and active), coupled with a quantitative limitation of percepts (depending on the limit of short term memory). The model has been implemented and tested in the context of a crossroad for which we have a set of observation data. The obtained results confirm the interest of the model to simulate the behaviors of drivers more realistically, and to improve interindividual variations in the driver population

Pełny tekst źródłaThe aim of this work is to improve the understanding of the electrical response of chemo-resistive CPC sensors. EEA-37% CNP was chosen as model system due to its thermoplastic elastomer matrix filled with carbon nanoparticles. In a first step, the use a thin CPC transducers has allowed to demonstrate their good sensing performances for the quantification of barrier effect towards toluene vapour diffusion of montmorillonite platelets filled poly(amide 12) films. A specific experiment was created to study multi-physics phenomena induced in a flat sheet of CPC exposed to a VOC. The simultaneous monitoring of the behaviour of mass, temperature, volume and resistance has produced innovative results to be used to validate the numerical models developed subsequently. Specific experiments established a mathematical relation between solvent concentration and electrical resistivity. The development of a one-dimensional numerical model was found useful to interpret time lags and amplitudes of resistance variations through the visualisation of current densities depending on concentration gradients

Pełny tekst źródłaThis work aims at improving equipments used for the microelectronics ; in this case, vacuum pumps manufactured by ADIXEN. Two subjects, which are both related to the use of a variable speed pump, have been studied: a) quality management during the fabrication of integrated circuits, by means of the process chamber pressure regulation, b) recycling of the fluorine gag used for the cleaning of Silicon Oxyde deposition chambers. The first subject deals with pressure regulation by variations in the pump speed, in contrast to the standard way of the regulation by mechanical movements of a valve. We tried to make the variable speed regulation adaptable to every kind of equipment and customer process, by systematising the identification procedure of the pressure dynamical behaviour, and use this procedure to model the whole system. The identification determines a local linear model by means of Random Binary Series, used with the Matlab's Box-Jenkins function. The global modelling relies on the Design of Experiments Method, which enables us to study a large amount of parameters and action variables, expected to have an impact on the pressure dynamics, and thereafter create a procedure to adapt the model to any customer equipment. The second subject aims at making a fluorine gag recycling system, dedicated to the SiO2 deposition chamber clean. Actually, more than 80% of the cleaning species are not being used during the cleaning, and hence are lost. The idea is to rècover this unused part at the chamber exhaust, and inject it back into the chamber, after trapping the chemical reaction by-products. This is a difficult task because as fluorine is a dangerous gag, we had to make the system such as to keep the pressure as low as possible, without preventing the flow control which is essential to match the clean standard conditions

Pełny tekst źródłaThe aim of this study deals with the evaluation of the feasibility of using a new polyimide (PI) resin as a passivation layer for silicon carbide (SiC) semiconductor power devices operating above 200°C. Such components seem to be adapted to the needs of power electronics with more integrated systems or able to operate at higher environmental temperatures. The electrical measurements performed have shown that PI presents a good dielectrical rigidity with values of the breakdown field EBR in the range between 2 and 4 MV/cm up to 400°C. In addition, values of the static (DC) electrical conductivity typical of those of semi-insulating materials (10-12 to 10-8 O-1. Cm-1) have been observed between 200 and 400°C. One of the main contributions of this experimental work, supported by an understanding of the physico-dielectrical phenomena, has been to show the correlation between the DC conductivity measurements performed in PI using two different techniques (conduction current measurements and dielectric relaxation spectroscopy). Dielectric relaxation spectroscopy, coupled to a modeling of electrode polarization phenomena, appeared also as a quick and powerful tool to determine the electrical conductivity in insulators at high temperature. The second step of the study focused on the evaluation of the operating limit of PI in the point of view of the electrical property stability versus time at high temperature and as a function of the atmosphere nature (inert or oxidant gases). First, it has been shown that the targeted PI properties were not suitable at 400°C mainly because of a rapid occurrence of the material thermolysis whatever the environment atmosphere nature. By contrast, at 300°C in nitrogen, electrical properties remained relatively stable. In air, an atypical improvement versus time has been observed. .

Pełny tekst źródłaRoad traffic collisions, a global public health and socio-economic concern, claim 1.19 million lives annually worldwide. Lebanon, with a population under 6 million, contends with nearly 1,000 road fatalities each year. Challenges are amplified by population growth, increased household vehicle ownership, deteriorating infrastructure, and the enduring impact of regional conflicts, all further obscured by fragmented data. The dearth of prior research on Lebanese road safety compounds the predicament, impeding informed policy formulation and precise solutions. The thesis unfolds along two main axes: road safety management and driver behaviour. The first axis provides a comprehensive analysis of the current state of road safety management in Lebanon. This analysis delves deeply into the challenges, as well as the historical, institutional, organizational, and financial complexities that shape the current framework for road safety. The thesis evaluates existing policies, enforcement mechanisms, budget allocations, and proposes evidence-based recommendations to improve both road safety and sustainability in Lebanon. This thorough analysis highlights the urgent need for a holistic strategy that covers a wide range of road safety aspects, from strict law enforcement to infrastructure improvements, sustainable funding allocation, and active international collaboration. Recognizing that data is the cornerstone of effective road safety management, the thesis addresses briefly the critical issue of fragmented and incomplete data on road traffic injuries in Lebanon. Focusing on the human factor, the second axis concentrates on driver behaviour, a key element of road safety that has lacked validated tools in the Lebanese context. The thesis advocates for the cross-cultural adaptation of four measurement scales (Traffic Locus of Control, Driver Behaviour Questionnaire, Driving Anger Scale, and Driver Skills Inventory) to understand and mitigate risky driver behaviours. This complex process involves translation, cross-cultural adaptation, rigorous validation, and the involvement of various groups of Lebanese drivers in data collection. Beyond validation, it explores the relationship between driver behaviour and road collisions, with the potential to influence road safety policies and promote good driving practices. This thesis thus serves as a transformative roadmap, aiming to create safer roads, reduce collisions, and improve the quality of life in Lebanon. It is a clarion call to address the urgent need for action and the pursuit of data-driven solutions

Pełny tekst źródłaThe powered two-wheelers (PTW) riders’ accidentality is at the heart of road safety issues. This PhD thesis is part of a comprehensive approach to generate knowledge on sex differences and sex stereotypes conformity within this very masculine stereotyped community. It first showed that female motorcyclists have much lower injury crashes and fatalities rates than males. A first study showed that males declared more intentional risky behaviors and female more non-intentional risky behaviors. A second study showed that the PTW type chosen had a more important effect on the aberrant behaviors than sex. A third study showed that individuals who conformed to masculine stereotypes declared more violations than those who conformed to feminine stereotypes (declared more lapses), whatever their sex. Motivations to ride a PTW explaining this relation. Finally, this work showed that sex stereotypes associated with motorcycle riding already existed on the adolescent population, from the age of 11, even if they are themselves moped riders or if at least one of their parents is a rider. As a conclusion, significant differences between male and female PTW riders were revealed, in terms of accidentology and risk taking. These differences are linked to the riders’ conformity to their sex group and to the effects of this conformity on their motivations to ride a PTW. Moreover, it also showed that sex stereotypes exist for this specific road users’ population. This work led to a more detailed understanding of PTW riders’ aberrant behaviors, and to enrich the thinking for actions with regard to road safety education and prevention

Pełny tekst źródłaThe aim of this work consists in improving knowledge concerning the cognitive and physical resources underlying motorcycle riding as well as riding performance itself. More specifically, we studied time-of-day and sleep deprivation effects of on these components. To reach this goal, six studies have been done. Innovating tools such as an instrumented vehicle and a riding simulator have been used as well as different levels of analysis. Taken together, these studies revealed a daily fluctuation of motorcycle riding performances, as it had been shown earlier for car driving. Motorcycle riding performance, as well as its underlying resources, increases during the day, from a low level at 06:00 h to a high level at 18:00 h. It is still the case when wake-up occurred 1 or 2 hours before driving and/or when participants had a light breakfast. Furthermore, this daily fluctuation of riding performances still appears after total sleep deprivation. However, the amplitude of this fluctuation decreases. During short term riding tests, riders appear to proceed to compensations between their different resources, in the sense that they regulate the level of activation of each resource to keep the global riding performance to an acceptable level. However, over 30 h of sleeplessness, especially when the task complexity increases, the negative effects of sleep deprivation are increased. In conclusion, these studies have a direct impact in regards to road safety and confirm the necessity to take into account the dangers of riding in a state of reduced vigilance

Pełny tekst źródłaWe tried to check, by the experimentalcontext of driving a car which was equipped to record different parameters of utilization, the influence of individual and personality criteria (respectively : sex, age, socio-professional level in the first case, impatience, emotional reliability, anxiety, agressiveness and dynamism in the se cond), or mental representations (such as the car, the aim, of driving, the motive of the trip), on the car driver's behaviour in terms of motor actions. The behaviour and psychometrical data analysis indicate that all of then contribute to the distinction between two two major patterns of driving, behaviour : firstly, the recklessness and agressivity of young people as well as men of a high socioprofessional level, are marked by the need for speed and little use of the brakes. These people consider driving only as a short-term aim and are always in a hurry and agressive when at the wheel. The car is a tool of self-promotion in their view. Secondly, the maturity and caution of women and experienced drivers are marked by the practice of lower speeds and a more frequent use ofthe brakes. These calm and relaxed drivers are able to'keep in mind the long-term aim of the trip and consider the car as a means of transport

Pełny tekst źródłaThe assesment of driver behaviour is a complex task essential to the anticipation and detection of driver performance degradation. This highly multi-field research involves the identification of early indicators of driver behavior under real driving conditions. Our methodology is based on three key components: the measurement of the driver’s nonconscious ANS (Autonomic Nervous system) reactions using non-invasive sensors; the video recording of environmental parameters and the measurement of driver behavioral responses using the car’s CAN network. This research resulted in the design and development of instrumentation specifically adapted for use under real conditions. The experimental phase involved the study of the driver’s use of the vehicule’s cruise control system (CCS). The driver’s reactions were monitored while using a faulty CCS. The recorded physiological signals evidenced variations in the driver’s mental state characteristic of dealing with an unexpected situation. The second experiment evaluated the influence of the CCS on the driver’s level of vigilance. Under these conditions, it was shown that the CCS does not result in a decrease in vigilance. On the contrary, a rise in driver’s sympathetic activity level was recorded. This work was carried out in collaboration with Renault S. A

Pełny tekst źródłaThis work is situated within the research area of automobile driving amongst the elderly. In the context of an ageing population, the autonomy of the elderly subject is very dependant upon their ability to drive and must be encouraged. If the proportion of accidents involving elderly people is lower in relation to the total number of accidents, consideration of the exposition factor multiplies by 2. 4 times the risk of people in the 65 years plus age group compared to the 24 - 65 age group. Our work has consisted of studying healthy subjects whilst maturing, selected on medical and neuropsychological criteria. Our studies have centred on objective data measured by simulated driving and subjective data about daily automobile driving. As well as the interest given to the effects of endogenous and exogenous factors, we were particularly interested in the adaptation strategies of the oldest subjects. Subjective results show that the elderly demonstrate an important need to use their vehicle they are aware of, and confident of their abilities but nevertheless one uneasy when interacting with other drivers, for them this is a harrowing experience. The most often described adaptive strategy is the increase in distance between vehicles, which is already seen to appear within middle-aged subjects. The obtained results under simulated conditions show that elderly people adapt their behaviour according to the difficulty of the driving conditions. The use highway lighting very well and are more able than young subjects to deal with long periods of night time driving. The driving behaviour of men and women, independent of driving experience, is separated by the process of ageing. Simulated situations revealed that within elderly subjects non adaptive behaviours to automobile driving which is due to physio, psycho and behavioural characteristics, is linked to age. We propose to consider that the behaviour of the elderly driver is an expression of their automobile driving adaptation and their abilities, or those which they believe they have, or are ready to assume, and not in a intention to reduce their risk or increase safety on the roads

Pełny tekst źródłaBig Data is gaining lots of attentions from various research communities as massive data are becoming real issues and processing such data is now possible thanks to available high-computation capacity of today’s equipment. In the meanwhile, it is also the beginning of Vehicular Ad-hoc Networks (VANET) era. Connected vehicles are being manufactured and will become an important part of vehicle market. Topology in this type of network is in constant evolution accompanied by massive data coming from increasing volume of connected vehicles in the network.In this thesis, we handle this interesting topic by providing our first contribution on discussing different aspects of Big Data in VANET. Thus, for each key step of Big Data, we raise VANET issues.The second contribution is the extraction of VANET characteristics in order to collect data. To do that, we discuss how to establish tests scenarios, and to how emulate an environment for these tests. First we conduct an implementation in a controlled environment, before performing tests on real environment in order to obtain real VANET data.For the third contribution, we propose an original approach for driver's behavior modeling. This approach is based on an algorithm permitting extraction of representatives population, called samples, using a local density in a neighborhood concept

Pełny tekst źródłaThis thesis was focused on the analysis of the impact of a collision warning system on information processing and driver behaviour in simulated driving. The objectives of this work were 1) to determine the impact of a warning signal associated with a collision warning system on the processing of information using evoked potentials, 2) to analyse the effectiveness of such a system according to its reliability, 3) and according to the drivers’ attentional state, 4) to examine the behavioural adaptation to the system over time. Using an electrophysiological and behavioural dual approach, we showed that the warning signal acts at the level of anticipation and response preparation and at the level of cognitive processing. Moreover, we confirmed that collision warning systems do not need to be completely reliable to be effective. We also observed that the effectiveness of the warning signal associated with the collision warning system was lower in distracted subjects, especially when the cognitive load associated with the distraction was high. This suggests that the warning signal requires attentionnal resources in order to be processed and, therefore, to be effective. Concerning behavioural adaptation to the system, the main results showed firstly that the immediate introduction of the system had a positive effect on the driving behaviour and secondly that the process of adaptation of the system at the longer term may be affected if drivers are distracted by high demanding secondary tasks

Pełny tekst źródłaThanks to new advances in automotive technology, innovative active safety devices can be designed to avoid accidents or reduce their severity like active braking booster. The trigger and the action of these devices are often based on drivers' behaviour. Nevertheless their efficiency depends, on one hand, on the representativeness of the experimental or real data used for their tuning, and on the other hand, on the determination of the trigging criteria. Thus an experiment was performed on open road. About a hundred of volunteers, women and men of various ages drove around 100 km (60 miles) in the Paris area for 2 hours. After a general analysis of driving, based on a statistical exploration using multiple correspondence analysis of the vehicle's dynamical parameters, 23000 braking actions were analysed to :characterise the drivers' actions while braking,study the influence of sex, age, driving experience,improve the efficiency of active braking based on drivers' actions

Consequently, we aim to create different driver behavior models for testing trucks regarding fuel consumption and average speed issues, i.e., rational driving. We propose a two-step method to model more accurately driving behavior: first, the identification of driving events through driving features. Second, the quantification of three different driving behaviors on the recognized driving events. Then we implement our results in a tool that creates these different driving behaviors. The output of this tool is a cycle adapted to a driver type in terms of fuel consumption and average speed, and that can be used in simulation and on chassis-dynamometer. The classification of driving events reaches classification rates between 74% and 91% depending on the events. We believe that they are sufficient for our application due to the raw nature of driving events and the similarities between the different classes. We also obtain promising results concerning the correlation between driving features and rational driving index. We focus especially on typical events, namely roundabout on extra-urban roads, toll on highways and stop on urban roads. The results of the developed tool prove to be efficient since we can now simulate different driving behaviors. On our test run in simulation, adapting only 10% of the events of a cycle produces fuel savings of 1.5% and an average speed which is 3% faster for an efficient driver than a non-efficient driver. These results are promising and we need to implement other events in the future

Pełny tekst źródłaThe aim of this work is to elaborate structural composites carbon fiber/polymer/metallic nanowires with high transverse electrical conductivity. First, silver nanowires (AgNWs) with high aspect ratio were synthesized through the polyol process in presence of poly (vinyl pyrrolidone). Those nanowires were inserted in the high performance thermoplastic polymer PEKK. The influence of the chemical and physical structure on PEKK properties will be discussed. PEKK/AgNWs composites showed a very low percolation threshold (0.6 vol %) and reach high electrical conductivity values of 200 S.m-1. Influence of the content filler in PEKK matrix was studied. Then, carbon fiber reinforced composites FC/PEKK/AgNWs were performed with good quality impregnation and good dispersion of AgNWs through the composite. The conductivity of the single tape CF/PEKK was increased by 4 orders of magnitude with the presence of AgNWs

Pełny tekst źródłaWe have studied the modifications in the behaviour of the electron gas at low temperatures and the ground state of single-chain quasi-1d conductors (TMTSF)2X associated with the presence of non-centrosymmetric anions (X). The ground states can be either insulating (due to the formation of a spin density wave phase or ta the anion ordering), or superconducting, or even metallic. Our study confirms the important role of pressure in establishing the SC ground state and shows the dominant effect of non-magnetic impurities on the mutual stability of SC and AF phases. Applied pressure provides the conditions necessary for SC coupling and transforms staggered anion ordering into an uniform one compatible with the metallic behaviour and the SC ground state. However in those compounds with dipolar anions or in the alloys, the SC ground state is easily suppressed due to the strong random potential along the conducting chains which is created by the anions. Moreover, the degree of order on the anion chains plays a decisive role in the competition between the AF and SC phases: the disorder favours the former, while a uniform order is compatible with the latter. We discuss the extreme sensitivity of the superconductivity ta the presence of non-magnetic defects in the framework of two theoretical models depending on whether the SC ground state is singlet or triplet. However, the proximity of the AF and SC ground states in the phase diagram, as well as the fact that the magnetic susceptibility is almost temperature independent are somewhat more compatible with triplet pairing. Nevertheless, independently of the nature of the SC ground state we conclude that a one-particle approach is too restrictive and that an analysis taking into account cooperative precursor effects is necessary to understand the unusual properties of the SC ground state in the (TMTSF)2X compounds and their alloys
