Abiding by the law when it does not exist: The case of the helmet bicycle law
2020
To improve the safety of bicycle users, some countries have enacted, or considered enacting, mandatory helmet legislation. Of course, the enactment of such legislation in a country assumes that its citizens will be well-informed of it, and consequently, will use the helmet more frequently than before. However, in the survey described in this paper we found that many people are not aware of the legislation in force in their own country, or, even if they know, they may not necessarily behave as dictated by the law. Thus, the effects of mandatory helmet legislation may be somewhat different than desired or expected. Therefore, the goal of this paper is to ascertain the role of cyclists' knowle…
Consistency Between the Subjective Perception of Feeling Indisposed, the Decision to Drive and Driving Performance
2016
Drivers' health and fitness are essential issues in order to predict traffic crashes, taking into account that these characteristics are essential to perform this task correctly and safety. The purpose of this research was to analyze the frequency in which drivers who feel physically or emotionally unable to drive decide to perform this task, or not, under states of indisposition, as well as the perception of the effect that this indisposition had on driving. This cross-sectional study used a total sample of n=1200 (666 [56%] men and 534 [44%] women) Spanish drivers, who answered a questionnaire designed to collect data about their psychosocial characteristics, driving habits and perception…
SAFETY CONSIDERATIONS ON TEENAGE PEDESTRIAN-BUS IMPACT
2019
This work studies the impact conditions between the adolescent pedestrian and the bus focusing on head and chest injury. The injury to the head is analyzed using both the Head Injury Criterion (HIC) 36 and the HIC15 parameters as established by the most advanced legislation and comparing the risk probability Abbreviated Injury Scale (AIS3+) and AIS4+. The parameter HIC15 gives a higher probability of risk with lower values, and therefore it can be considered more conservative. Moreover, the study of chest injury is performed with two different biomechanical parameters: the Thoracic Trauma Index (TTI) and the TTI(d); the last neglects the pedestrian mass. The results indicate that the param…
Socio-demographic, personal, environmental and behavioral correlates of different modes of transportation to work among Norwegian parents
2016
Abstract Background Cycling and brisk-walking to work represents an opportunity to incorporate sustainable transport related moderate- to- vigorous physical activity (MVPA) into daily routine among adults, and thus, may make an important contributing to health. Despite the fact that walking and cycling is an option for many commuters and also brings a number of benefits, a considerable proportion of commuters choose to use other means of transport when cycling and walking would be a highly appropriate transport mode. The object of this study was to assess the associations between modes of commuting to the workplace among parental adults; taking socio-demographic, personal, environmental and…
Les mobilités urbaines et leur impact sur l’exposition au bruit : simulation de scénarios prospectifs appliqués à la ville de Besançon
2015
Le modele MobiSim a teste le lien entre la modification de l’offre de transport et l’exposition au bruit dans ses dimensions spatiales et temporelles, le test etant applique a l’agglomeration de Besancon. C’est la desynchronisation des activites, le report modal et les changements dans les grilles horaires des transports collectifs qui produisent des effets reduisant ou bien augmentant l’exposition au bruit selon les lieux et les moments, les populations concernees etant elles-memes socialement diversifiees.
Using UAV Based 3D Modelling to Provide Smart Monitoring of Road Pavement Conditions
2020
Road pavements need adequate maintenance to ensure that their conditions are kept in a good state throughout their lifespans. For this to be possible, authorities need efficient and effective databases in place, which have up to date and relevant road condition information. However, obtaining this information can be very difficult and costly and for smart city applications, it is vital. Currently, many authorities make maintenance decisions by assuming road conditions, which leads to poor maintenance plans and strategies. This study explores a pathway to obtain key information on a roadway utilizing drone imagery to replicate the roadway as a 3D model. The study validates this by using stru…
Availability, demand, perceived constraints and disuse of ADAS technologies in Spain: findings from a national study
2019
Advanced Driver Assistance Systems (ADAS), created for enhancing the driving experience and actively preventing road crashes, have been progressively incorporated in vehicle designing essentially during the last decade. However, the literature has shown how some of these assisting technologies are not used by drivers in tandem with their potential. The aims of this study were, first, to examine the availability and demand of ADAS technologies among Spanish drivers and, secondly, to explore the perceived constraints and discouraging reasons for avoiding the use of ADAS available in their vehicles. For this national cross-sectional study, data from 1,207 Spanish drivers were analyzed. The res…
Les apports du modèle de recherches d'expériences à l'analyse du comportement dans le domaine culturel Une exploration conceptuelle et méthodologique
1995
International audience; Le modèle de recherche d'expériences de Holbrook et Hirschman a été présenté par ses auteurs comme un cadre conceptuel bien adapté à l'analyse des comportements dans le domaine culturel. Cette recherche analyse la capacité de variables explicatives des différences interindividuelles retenues par ce modèle à expliquer des différences dans les évocations affectives du théâtre par le public. La méthodologie mise en œuvre s'appuie sur l'analyse statistique de données textuelles recueillies auprès des différents segments de spectateurs.
Perdre ou renoncer aux étoiles : analyse des discours médiatiques et paroles de chefs à l’ère de la transparence
2020
Dans le cadre de cette contribution, la perte ou le renoncement aux etoiles du Guide Michelin de 19 chefs sont etudies a partir d’un corpus mediatique issu de la presse nationale ou de la presse regionale entre 1996 et 2019. L’analyse des discours tend a souligner les tensions qui traversent la restauration gastronomique et interroge egalement les modalites d’evaluation et de communication. Ce travail permet plus largement d’interroger la place et la nature de la critique gastronomique dans une ere de la transparence.
Études scientifiques et marché du travail : éléments de réflexion sur la crise des formations en sciences
2007
Student disaffection towards sciences, most evident in pure science undergraduates, is causing increasing concern for the future of scientific training in France. If access to employment deteriorates more for science graduates than for graduates in other disciplines, science graduates will have a distinct advantage in terms of earnings and employment status, when the economic situation becomes less favourable. Within sciences, graduates of pure sciences have a more difficult transition from education to employment than those from applied sciences. Yet graduates from both disciplines compete for the same job in the private sector with pure science graduates receiving lower wages. The “crisis…
