The Road/Lane Departure Warning System is a crash-avoidance technology which warns drivers if they are drifting (or have drifted) out of their lane or from the road. This warning system is designed to help prevent the possibility of a run-off-road crash. This system will not take control of the vehicle; it will only let the driver know that he/she needs to steer back into the lane. This warning system is not designed as a lane-change monitor, which addresses intentional lane changes, or a merging system which warns of other vehicles.
This informational report applies to OEM and after-market Road/Lane Departure warning systems for light-duty vehicles on relatively straight roads with a radius of curvature of 500 m or more, and under good weather conditions. Future revisions should consider the implications of newer variations on the user experience.
Rationale
Detailed human interface recommendations do not currently exist for road or lane departure warning systems. Knowledge of driver behavior regarding in-vehicle warning systems has not yet been compiled into a document specifically for road or lane departure warnings. The information given in this report will assist designers in the creation of the human interface for road/lane departure warning systems.
The Safety & Human Factors Steering Committee considers methods for defining, developing, and evaluating human-machine operating characteristics for advanced vehicle systems. Human factors is a cross-cutting discipline that has applications to the design, operation, and evaluation of the human-machine interface elements in vehicle and infrastructure systems. The Steering Committee addresses issues of interface design, driver workload, safety, system complexity, ease of use, and the response of drivers to automatic control systems, especially with regard to risk compensation. The Steering Committee also provides input to the work of ISO TC22 SC39 (Formerly ISO TC22 SC13).Steering committee reporting to MVC
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
