Drive-By Road Condition Assessment Using Internet of Things Technology

In this paper, we present a fully automated road assessment methods using cellular based internet of things platforms. The vibration data recorded from accelerometer sensor attached to a moving car is transmitted over the internet via cellular network to the monitoring server. At the monitoring server side, the vibration signal is used to calculate the international roughness index as a measure of the road surface roughness and its values are visualized on the road map for different road segments. Also, the possibility of using smartphone with built in accelerometer is investigated and its performance is compared with other proposed platforms.
