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 &#8220;muling&#8221; data on a user&#8217;s cell phone or USB key, to a central &#8220;portal&#8221;, 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.<\/p>\n<p>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.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>CarTel is a software and hardware platform for opportunistic sensing using moving vehicles that has been under development since 2005.
