Keyword: Control SystemMinimizing Collisions of Self-Driving Cars by a Control System Using Predetermined Two-Dimensional Grid Localization
Most crossroads use a traffic light to communicate between human-driven vehicles by conveying to the drivers when to stop and when to proceed in an organized fashion. However, the stop and wait nature of traffic lights cause slower mobility, leading to congestion. This paper presents a localization scheme based on two-dimensional (2D) flat geometry adaptation…
