A lane detection system used behind the lane departure warning system uses the principle of Hough transform and Canny edge detector to detect lane lines from realtime camera images fed from the front-end camera of the automobile. A basic flowchart of how a lane detection algorithm works to help lane departure warning is shown in the figures.
The lane detection system used by the lane departure warning system uses image processing techniques to detect lane lines from real-time camera images fed from cameras mounted on the automobile. Examples of image processing techniques used include the Hough transform , Canny edge detector , Gabor filter and deep learning .
Lane centering assists the driver in keeping the vehicle centered in a lane. [41] A lane-centering system may autonomously take over the steering when it determines the driver is at risk of deterring from the lane. [41] This system uses cameras to monitor lane markings to stay within a safe distance between both sides of the lane. [42]
A simple collision avoidance system. In transportation, collision avoidance is the maintenance of systems and practices designed to prevent vehicles (such as aircraft, motor vehicles, ships, cranes and trains) from colliding with each other. They perceive the environment with sensors and prevent collisions using the data collected from the sensors.
The advanced traffic management system (ATMS) field is a primary subfield within the intelligent transportation system (ITS) domain, and is used in the United States. The ATMS view is a top-down management perspective that integrates technology primarily to improve the flow of vehicle traffic and improve safety.
Operational design domain (ODD) is a term for a particular operating context for an automated system, often used in the field of autonomous vehicles. The context is defined by a set of conditions, including environmental, geographical, time of day, and other conditions.
Gradually, existing systems were stabilized, followed by the introduction of disc brakes and anti-lock braking systems. High-tech safety systems were first introduced in 1995 with Electronic Stability Control (ESC). Lane departure warning systems were introduced in the year 1999, and radar assisted adaptive cruise control was introduced in 2005.
However, dynamic elements are now being introduced into road traffic management. Dynamic elements have long been used in rail transport. These include sensors to measure traffic flows and automatic, interconnected, guidance systems to manage traffic (for example, traffic signs which open a lane in different directions depending on the time of day).
