Reducing the risk of person in vehicular network is essential, has premier priority to be achieved with prominent specifics such as collision detection and avoidance. Advances in image processing, falling cost on hardware and others allowed decreasing number of accidents are involved and step out from it. Today, new vehicles list safety as one of the highest priorities and use it as their main selling points. Existing series can detect obstacles in the path, and apply the brakes faster than the car user can. Introducing sensor backed scheme using light control for detecting proximity entity at emergency and decision is made in advance to avoid risk due to fatigue while driving. Falling cost of camera technology, manufacturers are started to equip their vehicles with cameras positioned at various places around the body of the vehicle. To remove any blind spots while driving, where as unpredictable traveling object found. Aim of this scheme is for detecting when a vehicle meets risk zone, drifts out of lane, or when it is within the safe stopping distance of an object ahead of it. This system is vision based, Instead of using the camera again to calculate the distance of the object to determine whether it is within the safe stopping distance, a short wave sensor used. This is done to ensure if such a system is possible, based on minimal cost and hardware usage implementation would be built. © Springer Nature Singapore Pte Ltd. 2017.
