How does it work?
Lane departure warning (LDW) systems are those that provide alerts whenever a driver appears (i.e., a turn signal is not activated) to deviate too close to the edges of the lane or partially crosses the lane mark. They are primarily designed to reduce high-speed collisions on roads and highways.
LDW systems are usually composed of visual, audible and/or steering wheel vibrating warnings. LDW-only systems must be differentiated from lane-keeping assistance systems that automatically adjust steering to keep the vehicle in lane. Lane-keeping assistance systems can provide a warning before activating.
Lane departure warning is especially useful for drivers who drive a lot on highways and country roads. It is less useful for city drivers. The type of warning varies among automakers. Some use an alarm sound, while others cause the steering wheel or driver's seat to vibrate, creating the feeling of driving over rumble strips.
- Current systems are compatible with turn signals for lane change, so this action is not a problem for this technology.
- At this time, studies show that this type of technology represents a clear reduction in motorway collisions.
- They help keep the driver focused in the event of any distraction. In addition, the lane-keeping assist features can be very useful on long journeys.
- Lane marking quality (e.g., paint is scraped off by snow plow) and environmental conditions may affect LDW performance to the extent that they affect the system’s ability to identify traffic lanes.
- Many systems rely on having good, visible road markings, and may not be able to detect an unmarked roadside.
- Sensors such as cameras can be influenced by environmental factors such as lighting or precipitation.

- A neuroergonomics approach to driver's cooperation with Lane Departure Warning Systemsby Damien Schnebelen on October 6, 2023 at 10:00 am
Lane Departure Warning Systems (LDWS) are automation that warn drivers in case of immediate lane departure. While LDWS are associated with increased road safety, little is known about the neural aspects of the cooperation between an LDWS and the driver behind the wheel. The present study addresses this issue by combining fMRI and driving simulation for experienced and novice drivers. The results reveal brain areas activated immediately after warning: it involves areas linked to the alertness...
- Active and passive safety systems (not only) for senior citizens : Systems to increase road safetyby Isabella Ostermaier on June 5, 2023 at 10:00 am
BACKGROUND: Due to a constantly increasing life expectancy and the need to stay mobile at a high age, the proportion of over 65-year-olds in traffic accidents is increasing from year to year.
- Visual and steering behaviours during lane departures: a longitudinal study of interactions between lane departure warning system, driving task and driving experienceby Jordan Navarro on April 19, 2023 at 10:00 am
Lane Departure Warning Systems (LDWS) generate a warning in case of imminent lane departure. LDWS have proven to be effective and associated human-machine cooperation modelled. In this study, LDWS acceptance and its impact on visual and steering behaviour have been investigated over 6 weeks for novice and experienced drivers. Unprovoked lane departures were analysed along three driving tasks gradually more demanding. These observations were compared to a baseline condition without automation....
