Drivers who rapidly change speed while driving may be more at risk for a crash. We sought to determine the relationship of demographic, vision, and cognitive variables with episodes of rapid decelerations during five days of normal driving in a cohort of older drivers. In the Salisbury Eye Evaluation Driving Study, 1425 older drivers aged 67-87 were recruited from the Maryland Motor Vehicle Adm...

The use of cellular phones has skyrocketed in recent years, with more than 118 million subscribers in the United States as of July 1, 2001. Recent estimates suggest that cell phone users spend 60% of their cell phone time while driving. Reaction time is one of the important methods used to study a person's central information processing speed and fast coordinated peripheral movement response. T...

Although distracted drivers are claiming more and more lives each year, drivers continue to perform dangerous behaviors behind the wheel of a moving vehicle. Of all driving distractions, texting and driving has proven to be one of the most dangerous. This research investigated the effect of text messaging on driver reaction, and whether the effect varied as a function of gender. Thirty-five Wic...

Background: With an ever-increasing number of vehicles on the road, it is inevitable that drivers will need to call upon an increasing use of sensory and motor skills in order to negotiate safely through traffic. Vision is one of the major senses in human beings, and it is definitely necessary for safe driving. Approximately 95% of the sensory input to the brain required for driving comes from ...

212 words OK) Objective: To explore how a single master alarm system affects drivers’ responses when compared to multiple, distinct warnings. Background: Advanced driver warning systems are intended to improve safety, yet inappropriate integration may increase the complexity of driving, especially in high workload situations. This study investigated the effects of auditory alarm scheme, reliabi...

The article presents the standard method of evaluation car drivers’ psychomotor reaction times. A characteristic feature this is ability to conduct tests using real vehicles equipped with mobile measuring apparatus. Measurements are carried out on people whose task initiate specific maneuvers (such as: a braking or turning maneuver, combined and as well e.g., use an audio signal) in response ex...
