In regression analysis, the notion of population validity is of theoretical interest for describing the usefulness of the underlying regression model, whereas the presumably more important concept of population cross-validity represents the predictive effectiveness for the regression equation in future research. It appears that the inference…

U.S. transportation data suggest that the number of vehicle miles traveled has far surpassed new capacity, resulting in increased traffic congestion in many communities throughout the country. This article reports on traffic congestion around a university campus located within a small town. The mix of trip purposes varies considerably in this…

Context: Crash fatality and injury rates are higher on rural roadways than other roadway types. Although slow-moving farm vehicles and equipment are risk factors on rural roads, little is known about the characteristics of crashes with farm vehicles/equipment. Purpose: To describe crashes and injuries for the drivers of farm vehicles/equipment and…

The decision to develop a transportation master plan for a school or university is often is a gradual process determined by changes that might have seemed insignificant in the beginning, but have combined to create problems that no longer can be ignored. Many circumstances can bring to light the need for a transportation master plan. In some…

The critical need for physicians to become entrenched in the issues of older drivers and public safety is the focus of a training initiative developed as a component of an innovative geriatrics curriculum, Aging (Couple) Across the Curriculum. As the number of aging drivers in the United States rises, physicians can play an important role in…

In 2 experiments, the authors examined how characteristics of a simulated traffic environment and in-vehicle tasks impact driver performance and visual scanning and the extent to which a computational model of visual attention (SEEV model) could predict scanning behavior. In Experiment 1, the authors manipulated task-relevant information bandwidth…

The International Civil Aviation Organization (ICAO) is currently implementing a program to improve the language proficiency of pilots and air traffic controllers worldwide. In justifying the program, ICAO has cited a number of airline accidents that were at least partly caused by language factors. Two accidents cited by ICAO are analysed in this…

Background: Pedestrian injury is the third leading cause of unintentional injury and death among children 1-14 years old. The purpose of this study was to examine primary grade teachers' perceived role in pedestrian safety education. Methods: A total of 630 surveys were sent to a national random sample of primary school teachers and 54% responded.…

Emphasis on problem solving in mathematics has gained considerable attention in recent years. While statistics teaching has always been problem driven, the same cannot be said for the teaching of probability where discrete examples involving coins and playing cards are often the norm. This article describes an application of simple probability…

The Kansas City Missouri Public Schools through Title IV, Safe and Drug-Free Schools and Communities Program was awarded a grant from the Missouri Department of Transportation to focus on the reduction of underage drinking and driving and seatbelt compliance and distracted driving. The grant focused on educating JROTC staff and School Resource…

A series of linked relationships is advanced which together suggest changes should be made to training programs for airside drivers at major airports in the United States, Australia and the United Kingdom. Overall, the links suggest a relationship between the number of airside incidents such as collisions at airports, the ethnic diversity evident…

For many survivors of serious road trauma, the physical and psychological consequences are complex and lifelong. The longer-term psychosocial recovery experience for survivors, however, is rarely documented in the social work literature. This article reports on findings from a study of road trauma recovery experiences. The findings are presented…

Industrial policy is a highly controversial issue. The European Union (EU) justifies its industrial policy on the grounds of common problems across countries, its capacity to coordinate and reduce duplication of efforts, its capacity to control and limit member-state subsidies to industries, and its mandate for foreign trade and competition…

Objective: Cell phone use while driving is hazardous; it quadruples the risk of a collision and multiplies the risk of a fatality nine-fold. The National Highway Traffic Safety Administration estimates that 8% of young drivers and 5% of all drivers use cell phones while driving. Participants and Methods: The authors trained graduate student…

This paper reviews theoretical and empirical evidence relating to the effectiveness of fear (threat) appeals in improving driver safety. The results of the review highlight the mixed and inconsistent findings that have been reported in the literature. While fear arousal appears important for attracting attention, its contribution to behaviour…
