OBJECTIVES To estimate the contribution of driver sleepiness to the causes of car crash injuries. DESIGN Population based case control study. SETTING Auckland region of New Zealand, April 1998 to July 1999. PARTICIPANTS 571 car drivers involved in crashes where at least one occupant was admitted to hospital or killed ("injury crash"); 588 car drivers recruited while driving on public road...

PURPOSE Drivers adopt smaller safety margins when pulling out in front of motorcycles compared with cars. This could partly account for why the most common motorcycle/car accident involves a car violating a motorcyclist's right of way. One possible explanation is the size-arrival effect in which smaller objects are perceived to arrive later than larger objects. That is, drivers may estimate the...

Characteristics of cars, such as mass and age, play a significant role in crash severity, but their effect are difficult to quantify because of the great number of factors altering the outcome of a real world accident. In order to focus on the crashworthiness of cars, we examine risk factors of severity suffered by the drivers involved in two-car accidents recorded by the police between 1996 an...

introduction : in any car accident four factors may be involved: human factor, road, vehicle and environment. about 90 to 95 percent of car accidents in iran are caused by human factor which could be pointed out as driving errors, traffic misconception, tiredness, drowsiness, drug and alcohol consumption driving in dark hours (late night, early morning, and after lunch), youngsters' drivin...

Perception of the lead car’s braking was measured on-road when subjects of various levels of driving experience were looking at a digital display located at the lower part of the windscreen, at the speedometer level, or in the mid-console. The brake lights of the lead car were either working normally or switched off. The results indicated that the detection of the lead car’s brake lights, in da...

This study was aimed at investigating drivers' ability to detect a car ahead decelerating, while doing mobile phone related tasks. Nineteen participants aged between 20 and 29 years, (2000-125000 km driving experience) drove at 80 km/h, 50 m behind a lead car, on a 30 km section of motorway in normal traffic. During each trial the lead car started to decelerate at an average of 0.47 m/s2 while ...

Today, the expansion of the Federation of Automobile racing car increases the competition of Go-kart. Go-kart is one of the best and safest car racing competitions. A history of nearly a century in the world. Go-karts are tiny car that can be controlled with good stability on the road and curved path for drivers bring excitement and exhilaration. Stability and control when crossing the road ben...

Heavy vehicles are significantly longer and heavier than passenger cars and consequently have quite different acceleration and braking capabilities. Heavy vehicle manoeuvres are therefore likely to influence drivers’ vehicle-following behaviour differently to cars. Heavy vehicles can also influence the behaviour of drivers of other vehicles while following a heavy vehicle. This paper used data ...
