A SMART GPS-BASED IOT SYSTEM FOR BLACKSPOT NOTIFICATION

Abstract. An accident blackspot is a length of the road marked as having high road accidents potential. Various highways have become a nightmare to passengers, drivers and pedestrians in the recent past. One of the common causes of road accidents is a driver being unfamiliar with a road. Despite authorities using various methods to raise awareness of blackspots including the use speed guns detectors the rate of the accidents on the roads is still in an alarming rate. More often, signposts on the road can be vandalized or even be hit by a reckless driver. There is also an assumption that every driver reads and understands signposts. We propose an IoT system embedded on a vehicle and having ability to sense a blackspot from a given distance. After sensing the blackspot, the system then provides an audio directive that notifies a driver to be more careful and avoid overtaking. The proposed system was developed using GPS, microcontrollers, and GSM mobile technology. The system was tested using coordinates extracted from road sections marked as blackspots. The proposed system sends notifications to end users using GSM system chip.
