Abstract: As and when the automated driving systems are becoming more intelligent, concerns about their safety and reliability in the real world are becoming more prominent. In the lane changing scenario where the vehicle is in the interactive highways the right decision must be made for changing the lane. The behavior of the surrounding vehicles might be highly unexpected, especially when the vehicle is in an interactive environment like a lane changing scenario. Therefore, a safe, smooth, and efficient lane change maneuver is an essential task for automated vehicles. This paper mainly focuses on how Model Based Systems Engineering (MBSE) approach is applied to Lane Change Decision Aid (LCDA) systems and visual analysis of two case studies of lane changing scenarios that are carried out which helps for a better understanding of how LCA works.
