Identified Risk Factors Among Truck Drivers Circulating in France
2020
The growth of the European market for road-freight transport has recently led to important changes. Moreover, due to the geographical context of France, truck drivers from different countries circulate on French roads to deliver their goods. Having road safety concerns in mind and based on a literature review, as well as interviews, a French questionnaire has been developed. Aiming at collecting data among truck drivers from different European countries, the questionnaire has been translated into seven languages and has been administered at four highway rest areas in France. The collected data were analyzed by means of multiple correspondence analysis, which pointed out new links between wo…
Are long-haul truck drivers unusually alert? A comparison with long-haul airline pilots.
2020
Abstract Background Recent studies suggest heavy vehicle drivers self-estimate their sleepiness unexpectedly low during night duties. The present study compared sleepiness ratings of long-haul truck drivers with those of long-haul airline pilots during night and non-night duties. In addition, the correspondence between self-rated manifest and predicted latent sleepiness was examined in the two groups. Methods Twenty-two drivers and 33 pilots participated. Their working hours, sleep, on-duty sleepiness, and use of sleepiness countermeasures were measured in naturalistic conditions. Predictions of latent sleepiness were based on the measurements of working hours and sleep using the Sleep/Wake…
The self-reported causes of sleepiness in shift-working tram and truck drivers
2021
Identifying the causes of sleepiness in various safety-critical work environments is neces-sary for implementing more efficient fatigue management strategies. In transportation, little is known about drivers' own perceptions of these causes. Therefore, we instructed shift-working tram (n = 23) and long-haul truck drivers (n = 52) to report at the end of their shifts what made them sleepy if they felt so. These self-reports, measured on-duty sleepiness, and sleep amounts were recorded on every shift over a period of 2-3 weeks per driver. The causes of sleepiness were queried with smartphone applications and sleep logs. Sleepiness was measured with the Karolinska Sleepiness Scale (KSS) and sl…
Passenger Car Equivalent for Heavy Vehicles Crossing Turbo-roundabouts
2016
Abstract Turbo-roundabouts represent an innovative scheme of modern roundabouts which provides a spiraling traffic flow and requires drivers to choose their direction before entering the intersection, since raised lane separators mark the lanes on the ring. The configuration of the turbo-roundabout makes that patterns of conflict at entries with one and two conflicting traffic streams can coexist. This paper presents research efforts aimed at measuring quantitatively the effect of heavy vehicles on operational conditions of a turbo-roundabout. The study starts from the initial belief that the greatest constraints to the vehicular trajectories imposed by the turbo-roundabout necessarily impl…
Stratégie du e-commerçant, accessibilité du produit et logistique urbaine
2013
Several factors impact urban logistics, among them, the recent evolution of e-commerce, by the new flows that it introduces in the city. It seemed interesting to us to understand urban logistics in this way, taking an original point of view, that of the upstream part of the logistics chain, namely the e-commerce strategy. We were thus able to highlight strategic and structural choices having consequences on product accessibility and urban logistics.
A Gamified Mobility Experience
2020
We believe in the use of urban games to define new enjoyable experiences, change citizens’ unsustainable habits and educate them to new environment-and social-friendly ones. This paper presents MUV, an innovative action that has the power to engage citizens and foster sustainable mobility behaviors. MUV complements engaging HMIs with a participatory method within an iterative innovation process called the virtuous cycle (understand, involve, co-create, implement, experiment). The innovation process has led to a new game dynamic: Mobility as a Sport. It results in a rewarding personal mobility experience; the same rewarding sensations the athletes feel when they improve their results.
Collaborative Content Downloading in VANETs with Fuzzy Comprehensive Evaluation
2019
Vehicle collaborative content downloading has become a hotspot in current vehicular ad-hoc network (VANET) research. However, in reality, the highly dynamic nature of VANET makes users lose resources easily, and the transmission of invalid segment data also wastes valuable bandwidth and storage of the users&rsquo
Mikromobilitātes klimata paplašināšanās iespējas Ziemeļvalstīs - iespējas un draudi
2020
Anton Martikainen rakstītajā maģistra darbā tiks pētīta mikromobilitāte, kas specializējas e-skūteros – šobrīd esošs fenomens, kas aizsākās 2018. gadā Amerikas Savienotajās Valstīs un ienāca Eiropā 2019. gada sākumā. Darba teorētiskā pieeja ir balstīta uz teoriju, kas saistīta ar paplašināšanos - mobilitāte kā pakalpojums un trešo pušu loģistikas teorija, kurai ir svarīga loma e-skūteru nozarē. Mikromobilitāte ir kļuvusi par aktuālu tēmu visā pasaulē, mainot veidu, kā cilvēki pārvietojas. Autors savā pētījumā definēs mikromobilitāti, analizēs galvenos tirgus dalībniekus un precīzi norādīs uz iespējām un draudiem un, kā tos redz iekšējās un ārējās iesaistītās puses. Darba izstrādes laikā tik…
Road Functional Classification Using Pattern Recognition Techniques
2019
The existing international standards suggest a methodology to assign a specific functional class to a road, by the values of some features, both geometrical and use-related. Sometimes, these characteristics are in contrast with each other and direct the analyst towards conflicting classes for a road or, worse, one or more of these features vary heterogeneously along the road. In these conditions, the analyst assigns the class that, by his capability and experience, he retains the most appropriate, in a very subjective way. On the contrary, the definition of an automatic procedure assuring an objective identification of the most appropriate functional class for each road would be desirable. …
A value sensitive ABM of the refugee crisis in The Netherlands
2019
We develop an agent based model to characterize the wellbeing of newcomers (i.e. asylum seeking refugees) in the context of asylum logistics using Schwartz’s theory of values. The model produces recommendations for decision-makers with respect to avoiding catastrophic outcomes and maximizing best case outcomes. We conduct analysis to show that while a relatively simple set of conditions is necessary to avoid catastrophic outcomes, these conditions are insufficient to maximize the best case outcomes. Furthermore, the conditions that maximize one best case outcome do so at the expense of another. The result is a platform for decision-makers to understand tradeoffs in policies for government a…
