Iteris, Inc., Anaheim, Calif., has released the results of its recent International Driver Satisfaction Study for the deployment of its Lane Departure Warning (LDW) system in commercial trucks.

The study, conducted over a six-month period with commercial truck drivers in both the U.S. and Europe, indicates that they consider Iteris' LDW system a valuable safety feature. More than 140 drivers in the U.S. and 100 in Europe responded to the comprehensive survey.
Iteris conducted the study in an effort to gauge market receptivity as well as the effectiveness of its LDW system from drivers using the system first-hand on a regular basis. With more than 8,000 Iteris lane departure warning systems installed in commercial trucks in the U.S. and Europe, driver responses were overwhelmingly positive, with many citing specific examples of how the system made them more alert and assisted in potentially dangerous situations.
Below is a brief summary of U.S. data collected:
-- 98% believe the system can prevent accidents
-- 92% believe the system is a valuable safety feature
-- 71% say the system has made them safer drivers
-- 80% normally drive with the system enabled
-- 97% are satisfied or very satisfied with the system
Iteris' Lane Departure Warning System was the first product of its kind to be available on large Class 8 trucks in the U.S. and Europe. The system uses a windshield-mounted camera that tracks the lane markings and provides "virtual" rumble strips anywhere there are lane markings.
Using image recognition software and proprietary algorithms, the system monitors the relative position of the truck, and if it unintentionally crosses the lane markings, the system automatically emits a distinctive rumble strip sound on the right or left side depending on the direction of travel, alerting the driver to make a correction.
