This demonstration illustrates the design and development of a low-cost scalable system to assess the road quality and impact of road vibration. An IMU is used to measure the vibration caused due to uneven road terrain and a GPS gives the coordinate. The sensor module is placed on the vehicle (public buses, cars, bikes) for precision high-quality measurement and an app on a smartphone is used for large scale vibration sensing. We then overlay raw sensor data into a visual map.
The app is an attempt to scale the road quality measurement to ensure coverage of the vast number of metropolitan roads where the high precision system becomes unaffordable. Data logging and analytics are performed in the cloud. Thus, the project aims to cover most of the roads and record their quality to ensure good commuter experience by avoiding bad roads, and also provide data for concerned authorities.
