Road safety technology: Lane departure warning and lane keep assist systems

 

Close

Designed to automatically detect when a driver unintentionally drifts out of their lane without indicating, research shows that these systems can reduce the number of road collisions.

Regardless of how long the journey is, maintaining consistent road position and staying within your lane is of the utmost importance. As an aid to help drivers, lane departure warning and lane keep assist systems automatically scan ahead for visible road markings.

Similar in principle, both systems present drivers with an additional aid to help them on the road. Thanks to the use of a camera, usually fitted at the top of the windscreen, the driver will be alerted when unintentional lane drifting is detected.

Lane departure warning usually comes in the form of audio or visual alerts. Depending on the car, they may also come in the form of a vibrating steering wheel or driver’s seat.

More advanced lane keep assist systems will apply corrective steering or braking to keep your car in the lane.

Thankfully, the driver doesn’t have to manually do anything different for these systems to be active. The technology behind it is the most impressive aspect, taking into consideration the driver’s speed and road position.

Whilst maintaining focus and staying alert at all times is essential, both systems are examples of the incredible safety features on modern cars that help keep drivers safe.

The Road Safety Authority is recognised as the leading voice for road safety in Ireland and as a leading voice internationally. This recognition is built upon a strong record of driving positive change in the attitudes and behaviours of all road users, while effectively collaborating with many stakeholders, such as An Garda Síochána and the Health and Safety Authority, to save lives.
