Head, chest and femur injury in teenage pedestrian–SUV crash; mass influence on the speeds
2018
This work studies the teenage pedestrian–sport utility vehicle (SUV) crash; injury to the vital parts of the body, such as the head and chest, and to the femur is evaluated. More advanced injury criteria are applied, as provided in the rules. The multibody technique is applied by making use of SimWise software and of the teenager anthropomorphic model, the use of which is now consolidated. Head injury criterion (HIC) is used for the head, thoracic trauma index (TTI) criterion for the thorax in the case of side impact and 3 ms criterion in the case of frontal impact, while the force criterion is used for the femur. Both the TTI and femur load evaluation require non-substantial modifications…
Estimating the occurrence of traffic accidents near school locations: A case study from Valencia (Spain) including several approaches
2019
Traffic safety around school locations is a topic of particular interest given the large number of vulnerable users, such as pedestrians or cyclists, that commute to them at certain times of the day. A dataset of traffic accidents recorded in Valencia (Spain) during 2014 and 2015 is analyzed in order to estimate the effects that school locations produce on traffic risk within their surroundings. The four typologies of school in this city according to the academic levels they offer (All-level, Preschool, Primary, Secondary) are distinguished and taken into consideration for the analysis. Two time windows comprising the starting time in the morning and the evening time once day school has end…

Motivational and Emotional Aspects Involved in Driving
2001
It is evident that individuals display different behaviors when driving and especially when involved in accidents. These differences seem to be related in various ways to physical, mental and socio-environmental characteristics of the driver. It is also known that a wide range of situational variables that are all too common in our daily lives, such as fatigue, use of drugs, alcohol or certain medication; sleepiness and transitory behavioral alterations such as stress or anxiety, have a negative influence on driving.
Attività di interconfronto tra codici di trasporto atmosferico per la preparazione e la risposta alle emergenze nucleari
2019
In questo lavoro vengono presentati e confrontati i risultati ottenuti con tre differenti codici (FLEXPART, CALPUFF e ldX) per il trasporto atmosferico di inquinanti radioattivi. I codici vengono confrontati su una singola simulazione di un possibile rilascio incidentale alla stazione frontaliera di Gösgen (CH), in condizioni meteorologiche sfavorevoli per il territorio italiano. In this work we present and compare the results obtained iwth three different codes (FLEXPART, CALPUFF and ldX) for the atmospheric dispersion of radioactive pollutants. The codes are compared on a single simulation of a possible incident release in the Gösgen (CH) nuclear power plant with weather conditions that a…
Conversion of Existing Roundabouts into Turbo-Roundabouts: Case Studies from Real World
2012
Compared with roundabouts the main advantages of turbo-roundabouts are the reduction in the number of potential conflicting points and the lower speed of vehicles passing through the intersection, they both can improve safety conditions at the junction. Moreover, the physical delimitation among lanes limits the side-by-side accident risk. These aspects make turbo-roundabouts more appropriate than roundabouts when a higher level of safety has to be guaranteed, particularly in presence of relevant pedestrian and two-wheels traffic volumes. The present paper has three main objectives: (1) to discuss general design criteria and functional principles of turbo roundabouts, (2) to give the geometr…
La Prevención de riesgos laborales en el arte urbano
2017
Cuando pensamos en el mundo de los graffitis no lo solemos relacionar con la PRL, sin embargo la labor de estos artistas urbanos también se encuentra sometida a ciertos riesgos, por lo tanto deben de adoptar medidas de prevención y protección que les permita minimizar tales riesgos. El manejo adecuado de los equipos y el respeto a los datos ofrecidos por los fabricantes o suministradores de las sustancias, son imprescindibles para poder ejecutar los diseños y alcanzar el objetivo deseado de la representación gráfica de unas obras, que más allá de las afinidades o tendencias de cada persona, no dejarán indiferente al observador.
Increase in rear-end collision risk by acute stress-induced fatigue in on-road truck driving.
2021
Increasing road crashes related to occupational drivers’ deteriorating health has become a social problem. To prevent road crashes, warnings and predictions of increased crash risk based on drivers’ conditions are important. However, in on-road driving, the relationship between drivers’ physiological condition and crash risk remains unclear due to difficulties in the simultaneous measurement of both. This study aimed to elucidate the relationship between drivers’ physiological condition assessed by autonomic nerve function (ANF) and an indicator of rear-end collision risk in on-road driving. Data from 20 male truck drivers (mean ± SD, 49.0±8.2 years; range, 35–63 years) were analyzed. Over …
Truck Platooning Under Real Traffic Conditions: First Insights on Behavioral Adaptations and Gap Preference of Professional Drivers.
2020
Objective The aim of the study was to investigate (1) how different gap sizes are perceived by professional truck drivers under real traffic conditions and (2) whether semi-automated platoon driving leads to changes in driving behavior of subsequent manual driving. Background Platoon driving is a current branch in the development of automated driving in which two or more vehicles build a convoy. The lead vehicle is controlled manually while following vehicles are electronically coupled to it and drive semi-automated with small gaps in order to achieve a better traffic flow and potential fuel savings. Method In a real road experiment, 10 trained professional truck drivers completed a total o…
Delivery Truck Drivers’ Work Outside Their Cabs: Ergonomic Video Analyses Supplemented with National Accident Statistics
2014
Delivery truck drivers' work contains various physically and psychosocially demanding work situations. Fifteen drivers' and 8 other stakeholders' identifications of such work situations were examined by video analyses in this study. The identifications were analyzed in-depth by the researchers and compared with statistics on 3,507 accidents in the Finnish trucking industry. The aim was to determine what kind of identifications were made and to what degree the identifications coincided among the participants and with the accident statistics. The drivers' identifications differed from the statistics data. The statistics showed a significantly higher relative frequency of movement-related situ…
