BRAKE REACTION TIME IN SOUTH INDIAN DRIVERS

Author: J.Ashok, V.Suganthi

Category: Physiology

Abstract:

Background: Driving is a skill involving multitasking by the brain. The drivers are issued license for driving following the assessment of their motor skills and knowledge about road instructions. Since driving involves multitasking and it is a cognitive function therefore it has to be assessed prior to issuing the license. Reaction time is a good test to assess cognitive functions and therefore brake reaction time (BRT) is assessed in drivers of different age groups and gender to standardize the BRT.

Materials and Methods: 130 subjects from Veerapandi village in salem district, Tamilnadu were included in the study. They were divided into different age groups of both genders and their BRT was assessed. The study was conducted in a stationary car. An in house built vehicle braking timer is fixed to the electric circuit of the braking system of the car and is wirelessly connected to the reaction time software in the laptop. Whenever the stimulus is given the driver presses on the brake pedal and the time taken to react is recorded by software.

Statistical analysis and Result: Postmenopausal women had a lower VO2max than premenopausal women, which may be associated with a higher total and visceral fat mass in postmenopausal women.

Conclusion: The BRT assessed using a stationary vehicle with single stimulus gives an approximate value of < 1 second in the different age groups of both the genders. But the values vary with different methods and real life situations. This could be taken as an approximate value for this group of drivers.
