The continuous development of information and telecommunication technologies has led to the possibility of transferring data and information between people in real time, in just a few seconds, which has led to the emergence of new approaches to data collection. An example is crowdsourcing (networked mass of people), which involves collecting a large amount of defined data from a large number (mass) of people through the Internet, that is, embedded sensors in smart devices. These are most often mobile phones and then it is about the concept of mobile crowdsourcing – which is more widely accepted under the term crowdsensing. This paper shows how smart devices (mobile phones or tablets) can collect vibration data that occur while driving in road traffic – and still be used to detect irregularities in road infrastructure (potholes, bumps, etc.) in real conditions.
