Survey about pedestrian safety and attitudes toward automated traffic enforcement in Washington, D.C.
Pedestrians represent more than one third of all traffic deaths in Washington, D.C. The District plans to expand its long-standing automated traffic enforcement program in 2013 from speed and red light cameras to cameras to enforce pedestrian right-of-way laws at crosswalks and stop sign laws. This study collected information on the opinions, behaviors, and knowledge of D.C. residents related to camera enforcement and pedestrian safety issues. ⋯ Most residents supported speed cameras and red light cameras, but support was lower for stop sign and crosswalk cameras. Emphasizing the safety benefits of stop sign and crosswalk cameras and documenting the extent of safety problems at stop signs and crosswalks may increase support for these new forms of camera enforcement. Communities considering automated enforcement should take into account the opinions of pedestrians, even though they are not subject to camera citations.

Associations between heavy-vehicle driver compensation methods, fatigue-related driving behavior, and sleepiness.
There has been growing recognition that broader economic and organizational factors play a role in creating work environments that facilitate high-risk driving behavior. This study investigates the association between compensation methods for drivers, fatigue-related driving behavior, and sleepiness among Australian heavy-vehicle drivers. Specifically, we hypothesized that piece-rate compensation methods linked to performance outcomes would be associated with greater levels of fatigue-related driving behaviors and sleepiness. ⋯ RESULTS confirmed that performance-based compensation methods are associated with work practices that may exacerbate driving behaviors associated with fatigue. Despite this finding, however, performance-based compensation methods were not associated with higher levels of sleepiness. This highlights the presence of potential differences in self-selection, operational, or fatigue management practices that may be common to drivers paid under various methods. Implications of these results for safety policy and future safety research within the heavy-vehicle industry are discussed.

Child and youth traffic-related injuries: use of a trauma registry to identify priorities for prevention in the United Arab Emirates.
Traffic-related injuries are the main cause of death during childhood and youth in the United Arab Emirates (UAE), use of safety restraints by citizens is uncommon, rollovers are frequent, and current legislation does not protect rear-seat occupants. Because little was known about the circumstances of hospitalizations for traffic injuries to guide prevention, a trauma registry was used to assess causes and determinants for traffic-related injuries during childhood and youth (<19 years) and its value for prevention. ⋯ Male drivers and vulnerable road users were at an unusually high risk relative to females. A relatively high frequency of traffic-related head injuries among UAE children and youth, including rear-seat passengers and other vehicle occupants, suggests that considerable preventable morbidity is associated with nonuse of safety restraints and/or other factors such as excess speed and rollovers of 4-wheel drive vehicles. Trauma registries can be useful for prevention; inclusion of data on safety restraints and helmet use by road user type is essential.

To examine the impact of text messaging and other in-car behaviors on driving performance under simple and naturalistic road conditions in a driving simulator. ⋯ Engaging in secondary tasks while operating a motor vehicle may have deleterious effects on driving performance and increase risk, even under the simplest of driving conditions. Text messaging may constitute a "perfect storm" of risk compared to other in-vehicle tasks such as tuning the car radio. The current investigation demonstrated detrimental effects of text messaging on driving behaviors such as lane maintenance, speed maintenance, and shifts of attention, even under relatively ideal and naturalistic driving conditions (e.g., familiar route, good weather, no traffic).

Bicyclist-bicyclist crashes--a medical and technical crash analysis.
The purpose of this study was to analyze the actual injury situation of bicyclists focusing on accidents involving more than one bicyclist. A medical and technical analysis was performed as a basis for preventive measures. ⋯ The prevalence of bicycle-to-bicycle crashes is high. Most of these accidents occur in urban areas. Bicyclists should be considered as minimally or unprotected road users, with an unsatisfactorily low rate of helmet use. Though the average level and patterns of injuries is moderate, most of the severe injuries involved the head and extremities. However, there was no significant correlation between frequent helmet use and sustained injuries to the head of major AIS.
