Radar is a technology that can be used to detect distant objects not visible to the human eye. A predecessor of radar, called the telemobiloscope, was first used to detect ships in the fog in 1904 off the German coast. Many scientists have worked on the development and refinement of radar (Hertz with electromagnetic waves; Popov with determining…

Traffic lights are an important part of the transportation infrastructure, regulating traffic flow and maintaining safety when crossing busy streets. When they go awry or become nonfunctional, a great deal of havoc and danger can be present. During power outages, the street lights go out all over the affected area. It would be good to be able to…

Although learning has always been a central topic for philosophy of education, little attention has been paid to the notion of group learning. This article outlines and discusses some plausible examples of group learning. Drawing on these examples, various principles and issues that surround the notion of group learning are identified and…

Recent research has demonstrated that minority drivers receive disparate traffic stop outcomes compared with similarly situated White drivers. This research, however, is often not grounded within a theoretical framework and fails to examine specific combinations of driver demographics. This study addresses those shortcomings by examining research…

Sixty-seven deaths per week, nine per day, one every two hours: Motor-vehicle crashes are the number one killer of teenagers in the United States, and although fatalities have declined in recent years, almost 3,500 teenagers still die every year in motor vehicle crashes (NHTSA 2011). In fact, 35% of all deaths among 16- to 19-year-olds are…

This investigation examined how children and adults negotiate a challenging perceptual-motor problem with significant real-world implications--bicycling across two lanes of opposing traffic. Twelve- and 14-year-olds and adults rode a bicycling simulator through an immersive virtual environment. Participants crossed intersections with continuous…

According to the National Center for Injury Prevention and Control, motor vehicle crashes are the leading cause of death among Americans aged 2-34. Many states have adopted periodic motor vehicle inspection (PMVI) to ensure the safety of the highways, and states that have adopted PMVI report a reduction in highway fatalities. Deaths and injuries…

Child passenger safety remains an important public health problem because motor vehicle crashes are the leading cause of death for children, and the majority of children ride improperly restrained. Using a mobile app to communicate with parents about injury prevention offers promise but little information is available on how to create such a tool.…

Because of the large number of deaths, severe injuries and huge financial loss due to auto accidents and poor traffic management, road safety and traffic management have become very important areas of interest among research community. As a result, Vehicular Ad-hoc Network (VANET) becomes a promising technology to improve road safety and quality…

Pedestrians with visual impairments need to cross streets where traffic signals and traffic signage are not present. This study examined the influences of several interventions, including a pedestrian's use of a mobility cane, on the behavior of drivers when they were expected to yield to a pedestrian crossing at an uncontrolled crossing.…

This article examines alcohol-impaired collision metrics around nine sobriety checkpoint locations in Indianapolis, Indiana, before and after implementation of 22 checkpoints, using a pre/post examination, a pre/post nonequivalent comparison group analysis, and an interrupted time series approach. Traffic safety officials used geographical…

Road safety education is a complex phenomenon which should be viewed holistically if taken into account the interconnectedness of education, infrastructure and enforcement. Effective road safety education is specifically important for learners in the Further Education and Training (FET) band, as they are active contributors to a community. The…

The central phenomenon researched in this case study was higher education administrators' decisions to institutionalize a safe ride program at a small, rural college. The purpose of this single/within-site case study was to describe the changes that happened at a rural public institution of higher education and the surrounding community in the…

Numerous studies have shown that later school start times (SST) are associated with positive student outcomes, including improvements in academic performance, mental and physical health, and public safety. While the benefits of later SST are very well documented in the literature, in practice there is opposition against delaying SST. A major…

Teaching advanced video production is an art that requires great sensitivity to the process of providing feedback that helps students to learn and grow. Some students experience difficulty in developing narrative sequences or cause-and-effect strings of motion picture sequences. But when students learn to work collaboratively through the revision…
