Junction Design Theory: 5-Auxillary Lanes Breakdown (D2)- Acceleration and Deacceleration lanes

This video explains the importance and design considerations for deceleration and acceleration lanes in junction design, especially on high-speed roads. It covers how these lanes help drivers safely slow down or merge into traffic, discusses recommended deceleration rates and lane lengths based on design speed, and emphasizes the role of engineering judgment and documenting design choices.
