3. Problem Statement

A lane change (LC) is characterized as a section during which a vehicle initiates a movement towards an adjacent lane and maintains this movement, without reverting back to the original lane. To engineer an intelligent system ensuring vehicle safety and preventing road accidents on a four-lane configuration, the system aims to furnish realtime information about vehicle distances. In the event of minimal spacing between vehicles, the system triggers alarmsasaprecautionarymeasure.

4. Objective of the project

The Advanced Driver Assistance System offers timely notifications to the driver when they show signs of lane departure or when the distance between vehicles becomes insufficient. If there's a chance of unintended lane departure, the system employs both visual and auditory alerts,urgingthedrivertorespondpromptly.Thefocuslies on investigating vehicle-to-vehicle (V2V) communication and identifying perilous circumstances that contribute to road accidents.

6. System Architecture

Fig 1:System Architecture

Figure 1 shows the block diagram of Lane detection and Vehicle tracking. Lane detection methods commonly involve sequential steps: capturing images from a camera sensor, transforming them into frames, converting to grayscale, and applying image thresholding. Initial lane marks are identified through edge detection, followed by refining accuracy using Canny edge detection. Post Canny, region of interest (ROI) selection filters out extraneous edges,focusingonlane-relevantfeatures.Utilizingfeaturebased techniques, color and edge attributes of lanes are discerned, heightening accuracy. For straight lane detection, Hough line detection and Sobel operator are employed. The K-means algorithm, a proximity-based clustering approach, groups akin points into clusters. Despite sensitivity to starting points and manual cluster count specification, K-means++ mitigates these concerns by refining starting points, improving convergence and target positioning accuracy. This elevated accuracy serves the purpose of precise vehicle lane-change detection,

addressing demands for reliable detection in dynamic driving scenarios. The amalgamation of multifaceted processes, advanced features, and K-means++ aims to amplifylanedetectionprecision.
