TL;DR: A comparison of a wide variety of methods, pointing out the similarities and differences between methods as well as when and where various methods are most useful, is presented.
Abstract: Driver-assistance systems that monitor driver intent, warn drivers of lane departures, or assist in vehicle guidance are all being actively considered. It is therefore important to take a critical look at key aspects of these systems, one of which is lane-position tracking. It is for these driver-assistance objectives that motivate the development of the novel "video-based lane estimation and tracking" (VioLET) system. The system is designed using steerable filters for robust and accurate lane-marking detection. Steerable filters provide an efficient method for detecting circular-reflector markings, solid-line markings, and segmented-line markings under varying lighting and road conditions. They help in providing robustness to complex shadowing, lighting changes from overpasses and tunnels, and road-surface variations. They are efficient for lane-marking extraction because by computing only three separable convolutions, we can extract a wide variety of lane markings. Curvature detection is made more robust by incorporating both visual cues (lane markings and lane texture) and vehicle-state information. The experiment design and evaluation of the VioLET system is shown using multiple quantitative metrics over a wide variety of test conditions on a large test path using a unique instrumented vehicle. A justification for the choice of metrics based on a previous study with human-factors applications as well as extensive ground-truth testing from different times of day, road conditions, weather, and driving scenarios is also presented. In order to design the VioLET system, an up-to-date and comprehensive analysis of the current state of the art in lane-detection research was first performed. In doing so, a comparison of a wide variety of methods, pointing out the similarities and differences between methods as well as when and where various methods are most useful, is presented

TL;DR: In this article, an imaging system for a vehicle includes an imaging sensor and a control, which is operable to capture an image of a scene occurring exteriorly of the vehicle.
Abstract: An imaging system for a vehicle includes an imaging sensor and a control. The imaging sensor is operable to capture an image of a scene occurring exteriorly of the vehicle. The control receives the captured image, which comprises an image data set representative of the exterior scene. The control may apply an edge detection algorithm to a reduced image data set of the image data set. The reduced image data set is representative of a target zone of the captured image. The control may be operable to process the reduced image data set more than other image data, which are representative of areas of the captured image outside of the target zone, to detect objects present within the target zone. The imaging system may be associated with a side object detection system, a lane change assist system, a lane departure warning system and/or the like.

TL;DR: This easy to understand book presents a conceptual and realistic view of how IV systems work and the issues involved with their introduction into road vehicles.
Abstract: This book, a groundbreaking resource, offers professionals a comprehensive overview of cutting-edge intelligent vehicle (IV) systems aimed at providing enhanced safety, greater productivity, and less stress for drivers. Rather than bogging readers down with difficult technical discourse, this easy to understand book presents a conceptual and realistic view of how IV systems work and the issues involved with their introduction into road vehicles. Offering a thorough understanding of how electronics and electronic systems must work within automobiles, heavy trucks and buses, the book examines: (1) real world IV products, along with practical issues, including cost, market aspects, driver interface, and user acceptance; (2) current systems such as adaptive cruise control, lane departure warning, and forward collision mitigation; (3) the next wave of driver assist systems, including pedestrian detection, lane-keeping assistance, and seamless information flow between road vehicle and the road infrastructure; (4) traffic assist systems, in which intelligent vehicles automatically coordinate their movements to improve traffic flow; and (5) a view of the future of this rapidly evolving technological area.

TL;DR: In this paper, the authors present a vehicular imaging and display system that includes a rear backup camera at a rear portion of a vehicle, a video processor for processing image data captured by the rear camera, and a video display screen responsive to the video processor to display video images.
Abstract: A vehicular imaging and display system (10) includes a rear backup camera (12) at a rear portion of a vehicle (14), a video processor (18) for processing image data captured by the rear camera, and a video display screen (16) responsive to the video processor to display video images. During a reversing maneuver of the equipped vehicle, the video display screen displays video images captured by the rear camera. During forward travel of the equipped vehicle, the video display screen is operable to display images representative of a portion of the field of view of the rear camera to display images representative of an area sideward of the equipped vehicle responsive to at least one of (a) actuation of a turn signal indicator of the vehicle, (b) detection of a vehicle in a side lane adjacent to the equipped vehicle and (c) a lane departure warning system of the vehicle.
TL;DR: The minimum longitudinal spacing which the vehicles involved in a lane changing/merging maneuver should initially have so that no collision, of any type, takes place during the maneuver.
Abstract: One of the riskiest maneuvers that a driver has to perform in a conventional highway system is to merge into the traffic and/or to perform a lane changing maneuver. Lane changing/merging collisions are responsible for one-tenth of all crash-caused traffic delays often resulting in congestion. Traffic delays and congestion, in general, increase travel time and have a negative economic impart. We analyze the kinematics of the vehicles involved in a lane changing/merging maneuver, and study the conditions under which lane changing/merging crashes can be avoided. That is, given a particular lane change/merge scenario, we calculate the minimum longitudinal spacing which the vehicles involved should initially have so that no collision, of any type, takes place during the maneuver. Simulations of a number of examples of lane changing maneuvers are used to demonstrate the results. The results of this paper could be used to assess the safety of lane changing maneuvers and provide warnings or take evasive actions to avoid collision when combined with appropriate hardware on board of vehicles.
