SmartRoad: A Mobile Phone Based Crowd-Sourced Road Sensing System

In this paper we describe SmartRoad, a road sensing system that generates and collects mobile sensory data from vehicle-resident mobile phones, in enabling and supporting crowd-sourced road sensing applications and services, as an alternative to expensive road surveys conducted traditionally. We implement the SmartRoad prototype system, and deploy it on 35 volunteer users’ vehicles for 2 months, collecting about 4,000 miles of driving data.
