This thesis focuses on the design and development of an application that collects data from the sensors of mobile devices (smartphones and tablets) with Android operating system. Apps which collect data in this specific way are called crowdsensing applications. Data collection is opportunistic where users contribute indirectly to the collection of information, by simply starting the app. The data relates to the location of the user, the speed and the shakes caused by his movement, for purpose of further analysis (Big Data Analytics) in the future, by extracting useful information on congestion conditions and road surface quality, in real time. The application simulates the function of a speedometer using either the built-in GPS system or the device’s networks. Calculates acceleration, average and maximum speed, average and maximum acceleration, total time and the distance traveled. In addition, displays the user’s current location on the map, as well as the history of his routes.
