Applications built on top of this system can collect, process, deliver, analyze, and visualize data from sensors located on mobile units such as automobiles. A small embedded computer on the car interfaces with a variety of sensors in the car, processes the collected data, and delivers it to an Internet server. Applications running on the server analyze this data and provide interesting features for users. text/html 2007-07-22T21:27:43-04:00 Hari http://cartel.csail.mit.edu/doku.php?id=fleet_testbed&rev=1185154063&do=diff A CarTel-equipped car in the fleet testbed. ---------- Spatial coverage of the vehicles in the testbed. The red and yellow colors show extremely high activity, while green is lighter activity. Each vehicle runs usually runs for several hours every day, though some vehicles don't run on some days. text/html 2007-07-22T21:23:33-04:00 Hari http://cartel.csail.mit.edu/doku.php?id=p2_pothole_patrol&rev=1185153813&do=diff The Pothole Patrol (P2) uses the opportunistic mobility of sensor-equipped vehicles to detect and report the surface conditions of roads. Each car in the system carries a CarTel node with 3-axis acceleration and GPS sensors, gathering location-tagged vibration data at a frequency of 400 Hz (we would've liked to use a higher sample rate, but the sensors we use max out at 400 samples per second).
