This study compares the safety of bicyclists riding on bicycle boulevards to those riding on parallel arterial routes in Berkeley, California. Literature on the impact of motor vehicle traffic characteristics on cyclist safety shows that high motor vehicle speeds and volumes and the presence of heavy vehicles are all detrimental to cyclist safety. This suggests that cyclists may be safer on sid...

PURPOSE Pediatric all-terrain vehicle (ATV) injuries have been increasing annually for more than a decade. The objective of this study was to describe the riding behaviors, helmet use, and crash history of young ATV riders. METHODS A 38 question self-administered survey was distributed to a convenience sample of children at 4 agricultural fairs during 2007. A total of 228 surveys were reviewe...

BACKGROUND Bicycling is healthy but needs to be safer for more to bike. Police crash templates are designed for reporting crashes between motor vehicles, but not between vehicles/bicycles. If written/drawn bicycle-crash-scene details exist, these are not entered into spreadsheets. OBJECTIVE To assess which bicycle-crash-scene data might be added to spreadsheets for analysis. METHODS Police ...

BACKGROUND Bicycle use, despite its proven health and other benefits, is rarely part of everyday travel for many people due to the perceived risk of injury from collision crashes. This article investigated the role of physical vs. attention conspicuity in preventing bicycle crashes involving a motor vehicle in New Zealand. METHODS The Taupo Bicycle Study involved 2590 adult cyclists recruited...

This paper describes the development and evaluation of a riding simulator (RS) for two-wheeled vehicles to analyze rider control behavior from the viewpoints of human factors and control engineering. In simulator development, sense of realism is divided into riding sensation and handling feeling. In addition, they are governed by the motion equation and the required pseudo-experience. In this s...

A series of wind tunnel experiments were conducted in the University Surrey’s Environmental Flow with a 1:50 scale typical London street canyon to assess exposure cyclists riding group emissions polluting vehicles. propane source emitted from an Ahmed body was used model car exhaust and fast flame ionisation detector measure pollutant concentration around four for multiple configurations source...

A 438 volume 117 | number 10 | October 2009 • Environmental Health Perspectives Vehicles Concentrate Nicotine A study by Patrick Breysse et al. published online 25 August 2009 ahead of print in Tobacco Control found that vehicle passengers riding with smokers may be exposed to nicotine levels 40–50% higher than those found in restaurants and bars that permit smoking. Nicotine concentrations ins...

in comparison to other transportation modes, riding motorcycle is prone to accidents.  motorcyclists are more exposed to physical injury than the car drivers. many multi-vehicle motorcycles crashes occur, there is right-of-way violation takes place in which another vehicle turns in fronts of a motorcycle, or a sudden cross of path of an on-coming motorcycle. one main factor which leads to high ...

PURPOSE More youth are killed every year in the United States in all-terrain vehicle (ATV) crashes than on bicycles, and since 2001, one-fifth of all ATV fatalities have involved victims aged 15 years or younger. Effectively preventing pediatric ATV-related deaths and injuries requires knowledge about youth riding practices. Our objective was to examine ATV use, crash prevalence, and riding beh...
