How To Handle These Data?
If loop measurements are archived every 20 second, 4,000 single loop detectors require
24 * 3600 / 20 * 50 * 4000 = 864 MB storage space per day!
Remember this is just data from loop detectors. We have also accident data, freight data, video data, …, to deal with!
With these data in hand, how to manage and use them sufficiently to support our decision making?

That’s Why We Offer CEE 412
CEE 412: Transportation Data Management and Analysis
• Store and retrieve transportation data efficiently become increasingly important• Optimal decisions should be made based on computation results from these available data
This course will help to build up fundamental knowledge and skills for database design, data management, and basic skills for transportation analysis.

Intelligence Requires Data
With good traffic data, we can make our control systems smarter than this .
