The object of the Project is the construction of an Android mobile application, where traffic accidents will be recorded easily by the police via GPS to inform the citizens in real time. The purpose is to mark the dangerous points of the road network, where repeated accidents occur (Black Spots), so citizens can be warned in time to avoid further traffic accidents. The main part of our application is the recording of traffic accidents by the police and the accurate placement of markers on the map. Through this application, the state will be informed immediately about any recurring accidents and can take appropriate measures faster. Also, our application allows the users – citizens to have a visual and audio notification when they approach a black spot to pay more attention while driving.
