The diploma deals with all previous methods of measuring roadways friction coefficient, in addition, we described the development of new method for simplified and modern measurement of friction properties of roadways. Since the diploma is the development of an Android application that reads GNSS sensor and accelerometer data, we first analyzed the accuracy of sensor readings of several phones, and took action based on results. The original analysis and way of thinking (algorithm) was performed with the Python programming language and its Anaconda distribution. When the results were satisfactory, we implemented the same algorithm in an Android application written in Android Studio with the Java programming language. The result is a working Android application that simplifies measurements of the roadways frictional properties by measuring deceleration when braking the vehicle.
