Rationale: With the commercial availability of various Lane Departure Warning Systems (LDWS) and limited existing standards and regulations for trucks and buses greater than 4,546 kg (10,000 lb) Gross Vehicle Weight (GVW), a vehicle test procedure (T.P.) of common methods to evaluate the effectiveness of these systems is justified. These lane departure systems utilize various methodologies to identify, track and communicate unintended lane departure warning information to the operator so that unintended lane departures can be prevented. This document outlines a basic test procedure to be performed under ideal operating and environmental conditions and does not define tests for all possible operating and environmental conditions. Minimum performance requirements are not addressed in this document. Although a technology-agnostic test procedure is presented (i.e., the test procedure described herein serves vision-based systems, GPS-based systems, magnetic-based systems, etc.), future revisions or separate recommended practices will be developed to accommodate other technologies should the need arise.
