This study assessed the degree to which hazardous vignettes are perceived as dangerous and realistic by car drivers and motorcycle riders (Exp. 1) and whether riders could be distinguished from drivers on their performance in a commercial motorcycle simulator during safe and hazardous riding situations using the same hazards (Exp. 2). In Experiment 1, car drivers and motorcyclists received a qu...

This report is concerned with the selection of routes in a network along which to transport hazardous substances, taking into consideration several key factors pertaining to the cost of transport and the risk of population exposure in the event of an accident. Furthermore, the fact that travel time and the risk measures are not constant over time is explicitly recognized in the routing decision...

Today one of the priority goals any organization operating hazardous production facilities is to increase level industrial safety at all stages enterprise’s life cycle. To select methods and tools, namely various technical organizational measures aimed increasing it necessary conduct an in-depth analysis emergency situations, their consequences, also consider causes occurrence.

Machinery entanglements are a leading cause of hospitalized injury on Canadian farms. This study evaluates the role farm tasks play in the occurrence of machinery entanglement events. A retrospective case series of 41 entanglement injuries involving 35 farm-machinery types was assembled. Only a few limited tasks were implicated in the majority of entanglements. These tasks were as follows: (1) ...

This paper presents a method for the identification of hazardous situations on the freeways. For this study, about 18 km long section of Eastern Freeway in Melbourne, Australia was selected as a test bed. Three categories of data i.e. traffic, weather and accident record data were used for the analysis and modelling. In developing the crash risk probability model, classification tree based mode...

Future driver assistance systems will have to cope with complex traffic situations, especially at intersections. To detect potentially hazardous situations as early as possible, it is therefore desirable to know the position and motion of oncoming vehicles for several seconds in advance. For this purpose, we propose a combined approach that tracks the vehicle position and orientation over time ...
