The CarTel Automotive Mobile Sensor Networking System

Опубликовано 6 сентября 2016, 17:27

CarTel is a software and hardware platform for opportunistic sensing using moving vehicles that has been under development since 2005. Data is captured from GPS, Wi-Fi, and OBD-II interfaces and stored in a local database on each car. This stored data is transferred opportunistically, via available Wi-Fi networks, cellular modems, or by muling data on a user's cell phone or USB key, to a central portal, where users can browse and visualize it. To allow non-expert users to specify what data they would like to collect from remote vehicles, CarTel includes a simple database-like interface for programming and configuration. In this talk, I will discuss recent development in the CarTel system, focusing on applications of the technology to traffic, road surface quality mapping, and personal commute management, including several interfaces which provides a map-based interface for browsing thousands of hours of driving data collected from a fleet of 27 taxicabs that have been running the software for the past year. Finally, I will discuss new algorithms we have developed for cleaning, querying, and managing the vast array of data produced by this testbed.
