AbstractThe paper addresses the problem to vehicle speed calculation at road accidents. To determine the speed are used the PC Crash software and Virtual Crash. With both methods are analysed concrete cases of road accidents. Calculation methods and comparing results are present for analyse. These methods consider several factors such are: the front part of the vehicle, the technical feature of the vehicle, car angle, remote relocation after the crash, road conditions etc. Expected results with PC Crash software and Virtual Crash are shown in tabular graphics and compared in mathematical metho

Abstract:
The aim of this research was to investigate the performance of simulated traffic data for real-time crash prediction when loop detector stations are distant from the actual crash location. Nearly all contemporary real-time crash prediction models use traffic data from physical detector stations; however, the distance between a crash location and its nearest detector station can vary considerably from site to site, creating inconsistency in detector data retrieval and subsequent crash prediction. Moreover, large distances between crash locations and detector stations imply that traffic data fro

Background: The coronavirus disease 2019 (COVID-19) pandemic has had an important effect on medical education. Universities around the world responded to the crisis by announcing the immediate closure and substituted the in-person sessions with online ones. Methods: Iran University of Medical Sciences designed a platform for medical students. To maintain the social distance, only onethird of students living in the dormitory were present at the dormitory in this condition. Some training courses were divided into two parts and each group was supposed to participate in given courses in-person for

In this paper, the strain rate effect of energy absorption members in rolling stock is studied using the virtual testing model (VTM) for Korean high speed train (KHST). The VTM of KHST was simulated for two different strain rate conditions. The VTM is composed of FE models for structures, and nonlinear spring/damper models for dynamic components. To simplify numerical model for the full rake KHST, the first three units consist of full flexible multi-body dynamic models, and the remainder does 1-D spring/damper/mass models. To evaluate the strain rate effect of KHST, the crash simulation was pe

Traditionally, business and management subjects have been linked to what is known by one’s culture and business traditions in terms of how business dealings are operated and managed according to given and proven business and managerial theories, concepts, ideas, and overall best practices. However, as more and more technology has been introduced into today’s modern workplace, changes to the overall business landscape have gone from domestic to global to now virtual opportunities. Consequently, many of the traditional business and management fields have been undergoing a metamorphosis in order

Abstract:
Most of the common road accidents are due to the driver’s inappropriate behavior, lack of attention, tiredness, and road conditions which usually cause the vehicle to deviate from the roadway or crash into others. Although, thanks to the Steer-by-Wire system, recent research showed that is now possible to enhance vehicles’ manipulability and users’ safety by stimulating the drivers to react efficiently in common and critical situations. This paper describes a new strategy to assist the driver in his trajectories’ planning on a multiple-lane highway. A driving assistant is here designed to give

The COVID-19 pandemic has been a crash course for many in working from home using various online tools, many of which can be used to organize e-conferences. An e-conference is a fully online event with multiple sessions and virtual discussion in one platform. In this paper, we aim to provide insights in and present key steps to organize a successful e-conference, increase our understanding of the impact of e-conferences, and identify key strengths, weaknesses, and success factors. Based on a participant survey and our own experience, we found that e-conferences are relatively easy to organize

Simultaneously we have calculated in progress the simulation of vehicle crash with the basic theory of automobile collision, vehicle collision model and the law of conservation of energy and momentum.

The crash rate for young novice drivers is at least eight times higher than that of their experienced counterparts. Literature shows that the young novice drivers are not careless drivers but they are clueless drivers’ - clueless because of their inability to predict the risk ahead of time that might materialize on the forward roadway. Other error-feedback training programs exist that emphasize the teaching of risk awareness and perception skills to young drivers. In the current study, a Virtual reality based risk awareness and perception training program (V-RAPT) was developed on the Oculus R

Thirty-four drivers participated in a driving simulator experiment which investigated time and speed perception as it related to cognitive workload resulting from secondary tasks. Each participant drove the virtual drive twice, once with either an audio or a map task and again with no distractions as a control. Participants knew from a practice drive that they would be asked to estimate their speed and time duration of driving, thus this study used the prospective paradigm. Based on previous literature it was expected that there would be an underestimation of time and an overestimation of spee

Women in cyberspace do not escape patriarchal violence and are subject to strict social control exercised through technological means. Cyber-violence especially affects women with an explicitly feminist presence in virtual spaces. Their participation in and advocacy of feminist values are considered a transgression of the patriarchal mandate, which seeks to exclude women from public spaces or, failing that, to marginalise them. That is why they are the targets of grave intimidation, harassment and threats. At the same time, digital networks have spawned a plethora of spaces for women’s collect
