Using Iteris' AutoVue Lane Departure Warning system over the last four years, Prime has reduced rollover and run-off-road accidents by more than 62 percent
, the carrier announced.

The refrigerated, flatbed and tanker truck fleet now has over 4,000 trucks equipped with the Iteris LDW and has been tracking the miles of both the trucks equipped and not equipped since January 2006. Over that time, the trucks that were equipped with Iteris' LDW systems accumulated 761 million miles, while the non-equipped trucks accumulated 902 million miles. Performance was tracked based on a calculation of the number of accidents per million miles. The per-million-mile rate for run-off-road and rollover accidents was 62 percent less on the trucks equipped with Iteris' LDW system, which translates to about 84 fewer accidents.

"The investment Prime has made to install Iteris' Lane Departure Warning systems in our fleet of trucks has really paid off," said Robert Low, founder and president of Prime. "There has been a significant reduction in run-off-road and rollover accidents in the trucks that are equipped with Iteris' AutoVue LDW system."

Iteris' AutoVue LDW system is a small, integrated unit consisting of a camera, onboard computer and sophisticated image processing algorithms. The system's camera tracks visible lane markings and its algorithms detect when a vehicle drifts toward an unintended lane change.
