GoSafe: A power-efficient android application for road events signaling and notification

The lack of traffic signal intelligibility and insufficient information about road conditions is often cited as an important factor that leads to an increase of road accidents and fatalities. To overcome this problem, a number of systems have been developed in order to signal events to emergency points and designed to supply drivers with information about roads conditions to avoid approaching risks. With the important emergence of smart mobile technologies and their usage on a large scale, deploying these technologies within Advanced Driver Assistance Systems “ADAS” becomes a needed approach to significantly reduce road casualties. In this paper, we discuss the implementation of GoSafe, a smartphone based application and system that helps drivers to signal and receive notifications about roads events. GoSafe application is built with voice-based interaction command and notification. This application uses the network based localization technique as the main localization approach instead of the GPS receiver to improve power efficiency.
