Every year, hundreds of people are killed, and tens of thousands of people are injured, in car wrecks that involve an automobile leaving a lane of traffic improperly, resulting in a collision with another vehicle, or some other type of accident. The accidents tend to occur due to driver being inattentive or tired.
The National Highway Safety Administration reports that over 70 percent of all single vehicle highway accidents involve an automobile running off the roadway. At the other end of the spectrum, head-on collisions, with very serious consequences, occur when an automobile crosses into an oncoming lane of traffic.
Research suggest that the wide use of lane sensors not only will reduce the number of single vehicle accidents, but will reduce head-on collisions by 50 percent. An ever-increasing number of automobiles are being designed to incorporate lane sensors into their standard technology.
Overview of Lane Sensors
Lane sensors, also known more formally as lane departure warning systems, represent a group of fairly recently developed technologies that are designed primarily to reduce the risk of certain types of accidents on highways. These technologies are designed to prevent highspeed accidents, including incidents of an automobile running off a roadway and collisions involving a vehicle inappropriately crossing out of a travel lane.
Lane Warning and Lane Departure Assist Technology
The first type of lane sensor is called a lane departure warning, or LDW, system. This type of system is designed to monitor the lane markings on a particular roadway. When a vehicle begins to deviate from the lane of traffic, the departure warning system, or LDW, sounds an alarm.
The second type of lane sensor in use today is called a lane keeping system, or LKS. A lane-keeping system also monitor lane markings, as is the case with a lane departure warning system. However, unlike LDW technology, a lane keeping system actually is capable of taking corrective action to keep a vehicle in its proper lane of traffic.
Usually an LKS system is a two-part process. The system initially alerts a driver of the lane deviation issue. If the driver fails to take corrective action, the lane keeping technology does so in its own. The automatic correction by the vehicle includes both speed and steering components.
There remain limitations to this technology, although it continues to improve with each passing year. Weather conditions, including rain, snow, and bright sunlight, can impair the operation of a lane sensor system.
When buying a new car or truck consider upgrades, if available for early warning technology, it may save your life!
