Primary Form

Stop signs are the primary form of traffic control in the United States. However, they have a tendency to be much less effective than other forms of traffic control like traffic lights. This is due to their smaller size, lack of lighting, and the fact that they may become visually obscured from the road. In this paper, we offer a solution to this problem in the form of a mobile application implemented in the Android platform: StopWatcher. It is designed to alert a driver when they are approaching a stop sign using a voice notification system (VNS). A field test was performed in a snowy environment. The test results demonstrate that the application can detect all of the stop signs correctly, even when some of them were obstructed by the snow, which in turn greatly improves the user awareness of stop signs.

Abstract Study Objectives To analyze cognitive deficits leading to unsafe driving in patients with REM Sleep Behavior Disorder (RBD), strongly associated with cognitive impairment and synucleinopathy-related neurodegeneration. Methods Twenty isolated RBD (iRBD), 10 symptomatic RBD (sRBD), and 20 age- and education-matched controls participated in a prospective case-control driving simulation study. Group mean differences were compared with correlations between cognitive and driving-safety measures. Results iRBD and sRBD patients were more cognitively impaired than controls in global neurocognitive functioning, processing speeds, visuospatial attention, and distractibility (p<0.05). sRBD patients drove slower with more collisions than iRBD patients and controls (p<0.05), required more warnings, and had greater difficulty following and matching speed of a lead car during simulated car-following tasks (p<0.05). Driving-safety measures were similar between iRBD patients and controls. Slower psychomotor speed correlated with more off-road accidents (r=0.65) while processing speed (-0.88), executive function (-0.90) and visuospatial impairment (0.74) correlated with safety warnings in sRBD patients. Slower stimulus recognition was associated with more signal-light (0.64) and stop-sign (0.56) infractions in iRBD patients. Conclusions iRBD and sRBD patients have greater selective cognitive impairments than controls, particularly visuospatial abilities and processing speed. sRBD patients exhibited unsafe driving behaviors, associated with processing speed, visuospatial awareness, and attentional impairments. Our results suggest that iRBD patients have similar driving-simulator performance as healthy controls but that driving capabilities regress as RBD progresses to symptomatic RBD with overt signs of cognitive, autonomic, and motor impairment. Longitudinal studies with serial driving simulator evaluations and objective on-road driving performance are needed.

Navigation Service

Members of the Civil Air Navigation Services Organisation have committed themselves to measure and improve safety culture within their organizations by 2013 ( CANSO, 2010 ). This paper attempts to offer support to air navigation service providers that have already implemented a standardized safety culture survey approach, in the process of transforming their safety culture based on existing survey results. First, an overview of the state of the art with respect to safety culture is presented. Then the application of the CANSO safety culture model from theory into practice is demonstrated based on four selected case studies. Finally, a summary of practical examples for driving safety culture change is provided, and critical success factors supporting the safety culture transformation process are discussed.

The article describes the use of BYOD technology (Bring Your Own Device) in educational practice using the Lecture Racing mobile application. This application provides feedback between the teacher and students both in the classroom and during distance learning, contributes to the visualization of educational material and, in general, the informatization of the educational process. The purpose of the study is to conduct a theoretical analysis of the current state and prospects for the development of BYOD technology in Russia and abroad, and to test the benefits of using this technology in educational practice using the specific mobile application. During the study, an analysis of scientific, theoretical and practical literature on BYOD technology was carried out. In the process of experimental work, test tasks were the instrument of measuring knowledge and skills of students. As a result of a theoretical analysis and study of the practical possibilities of using BYOD technology (using the Lecture Racing mobile application as an example), it was found that this technology allows you to visualize information that is displayed in real time on the screen of each student's mobile device, regardless of its location. This technology also allows both the student and the teacher to quickly work with information, provide feedback, receive an independent assessment (since the assessment is set automatically), saves time, and develops the information culture of students.
