Effectiveness Of In-Vehicle Monitoring Systems For Teen Drivers
The Insurance Institute for Highway Safety (IIHS) conducted an interesting experiment in 2009 that tested the effectiveness of various in-vehicle monitoring systems on teen drivers. The study monitored the driving habits of 84 teen drivers with different types of in-vehicle technology to determine which ones had the greatest effect on both the teen drivers and their parents.
IIHS installed their own monitoring equipment in the study vehicles that recorded when drivers braked sharply or accelerated suddenly, didn't use belts, and exceeded speed limits. The monitors used GPS and a satellite modem to transmit the data to a central processing facility and the data was made available for parents to review. In addition to its own monitoring systems, IIHS also installed different types of in-vehicle monitoring that are commercially available to parents of teen drivers. The 84 subjects were randomly assigned into four groups:
"Drivers in groups 1 and 2 heard audible alerts for risky maneuvers. A short, low-pitched buzz sounded for sudden braking and acceleration. A continuous low-pitched buzz sounded when the belt wasn't buckled and stopped only when it was fastened. Speeding triggered a single beep at 2.5 mph over the posted limit, followed by continuous beeps at increasing pitch and frequency when the teenage drivers exceeded the limit by more than 10 mph." For drivers in group 1, the information was immediately recorded and transmitted to the parents for review. The drivers in group 2 had the opportunity to correct their behavior and, if corrected within 20 seconds, prevent a report from being sent to their parents.
There were no in-vehicle alerts for drivers in group 3, just website notification. Group 4, the control group, was monitored but had no alerts or web notification.
