Reporting the incidents to authorities in developing countries that can take actions has been a chaotic and slow process. This paper proposes an algorithm for a system that automatically reports events that compromise passengers’ safety to respective authorities by using spherical cosine rule. When an incident such as an accident, over speeding or overloading of passengers occurs the system identifies the closest police station. It does so by calculating the shortest distance between latitudes and longitudes of the place where the event occurred and those of the closest police station. Then it identifies the next police station which the bus will encounter and where the event can be reported and immediate action carried out. The public buses will be equipped with GPS which will generate coordinates and there will be a database which contains the coordinates for the police stations along the main roads.
