The portal shows users where they've recently driven.


Each trip is organized into a trace, which when viewed allows access to all accompanying sensor data.


Every once in a while, after a depressingly slow commute, you can see why on the portal. An average speed of 13 mph is enough to make one sick (or start biking). The red, orange, and yellow segments are slow; the greens are about average, and the blues are real fast (no blue below).

We use traffic flow data collected from our users' drives to determine congestion-prone road segments.


Users can graphically search through their traces to analyze their drives visually.


Users can also view the WiFi APs that were detected on their drives by selecting the right sensor overlay on the tab on the left (WiFi in this case).
