The ASTID (Advisory System for Tired Drivers) is a system which continually assesses the various factors known to contribute to, or to be indicative of, driver tiredness. After an assessment of these factors, visual and audible alarms are produce to warn drivers to the fact that they may be becoming tired before they themselves are aware of it.
Available from Measure-Tech Australia , the ASTID comprises two linked systems designed to advise and monitor a driver about his or her sleepiness whilst driving:
1. A "knowledge based" which forewarns the likelihood of drivers falling sleep over a 24 hour period by providing an electronic template. Also taken into consideration are the driver’s prior sleep patterns.
2. A "steering sensory" system which is able to detect : (i) monotonous driving and (ii) vehicle movement (steering) characteristics typifying sleepy driving. Information obtained from (i)& (ii) is processed and fed into the knowledge based system
The Advisory System for Tired Drivers has been developed using a software algorithm that incorporates sound scientific research into sleep and sleepiness by Loughborough Sleep Research Centre.
