Collisions of vehicle-to-vehicle and vehicle-to-vulnerable road user during right turns at intersection account for a high number of other intersection accidents in Japan. Considering such situations, “intersection right turn collision avoidance system” is intensely required. We focus on right turn scenario that the ego vehicle needs to negotiate with oncoming objects such as automobiles, motorcycles, bicycles and pedestrians. This paper presents a risk predictive safe speed control algorithm that introduces speed control braking assistance for safe right turn combined with autonomous emergency braking to avoid collision with other participants during right turn at intersections. Our proposal uses on-board sensors such as radar and cameras to handle situations without depending on C2X/X2C communication and infrastructure. Full-vehicle simulation for a rapid system development is used to verify the effectiveness of the proposed ADAS.
