Poster Abstract: Smart Road: A Crowd-Sourced Traffic Regulator Detection And Identification System
CPSWEEK(2013)
摘要
In this paper we present Smart Road, a crowd-sourced sensing system that detects and identifies traffic regulators, traffic lights and stop signs in particular. As an alternative to expensive road surveys, Smart Road works on participatory sensing data collected from GPS sensors from in-vehicle smartphones. The resulting traffic regulator information can be used for many assisted-driving or navigation systems. We implement Smart Road on a vehicular smartphone testbed, and deploy on 35 external volunteer users' vehicles for two months. Experiment results show that Smart Road can robustly, effectively and efficiently carry out its detection and identification tasks without consuming excessive communication energy/bandwidth or requiring too much ground truth information.
