Here’s how Wikipedia defines a lane: “A lane is part of a roadway (carriageway) that is designated to be used by a single line of vehicles, to control and guide drivers and reduce traffic conflicts.” – Read more here It’s important to put a formal definition to this because it enables us to proceed with the lane detection concept.

Which is the correct way to turn on a four lane road?

Begin the turn with your left wheels as close as possible to the yellow dividing line. Enter the road to the right of its center line. If the road onto which you are turning is a four-lane road, you may enter it in the right lane if the right lane is free of traffic.

How can we detect the lane markings in a video?

So, to detect a lane, we must detect the white markings on either side of that lane. This leads to the key question – how can we detect the lane markings? There are so many other objects in the scene apart from the lane markings. There are vehicles on the road, road-side barriers, street-lights, etc. And in a video, a scene changes at every frame.

How do you signal before you change lanes?

Before you stop, turn or change lanes, let the other drivers know what you are going to do by signaling. You can signal with your hand and arm or with your vehicle’s turn signals and brake lights. You should signal at least 100 feet before you turn so the other drivers can be ready.

Why is it important to know your lane position?

It is one of the most important research topics for driving scene understanding. Once lane positions are obtained, the vehicle will know where to go and avoid the risk of running into other lanes or getting off the road. This can prevent the driver/car system from drifting off the driving lane.

How to do real time lane detection in video?

The task that we wish to perform is that of real-time lane detection in a video. There are multiple ways we can perform lane detection. We can use the learning-based approaches, such as training a deep learning model on an annotated video dataset, or use a pre-trained model.
