What is RoadPhone App
The RoadPhone app is a smartphone application that collects the data by road users and upload it to the google cloud for processing.
All common smartphones have integrated motion sensors and GPS. The RoadPhone app is designed to allow road users to read those data from their smartphones and store to the cloud. For research purposes, the data collected include 3-axis acceleration data, orientations, gyroscope data, speed and precise locations, where precise locations enable the user to locate the anomalies and map them in the anomaly map accurately.

The App is comprised of 3 views.
Main view: direct to other views, select data saving directory, and show the real-time accelerations, orientations and precise positions.
