She showed us a video of traffic flow in the Bay Area - San Francisco and Oakland, including the Bay Bridge, Golden Gate Bridge, Interstate 80, highways One and 101 - over a 24-hour period. With colors representing different vehicle speeds (green for fast, yellow for medium and red for slow) it's easy to visualize how the traffic changes during the day and when / where hotspots exists. This data gives city and highway planners invaluable insight into ways to improve our roads. Another example used CAN bus data collected from taxis in Eindhoven, The Netherlands, to study driver behavior around a sharp bend.
