3. 3 Traffic Is Getting Worse Image Source: http://www.cartoonstock.com/directory/c/congested.asp

4. 4 Why? From the Bureau of Transportation Statistics, National Transportation Statistics 2009 6.3% 53.2% 95.7%

5. 5 Countermeasures  Construct new roads  Reduce traffic  Increase capacity of the existing infrastructure by employing ITS technologies  Travel demand control  Improve transit service

6. 6 Is It a Possible Approach? Do you think we can increase highway capacity by applying advanced technologies?

7. 7 Data Is Crucial for the Success of ITS Quality Data Control Center E-Message Sign ATIS !!

8. 8 Where Are the Data From? Traffic Detection Controller Sensors Data Archive Data Server

9. 9 Details? CEE 579 Advanced Traffic Detection Systems 3 credits. Spring Quarter  General introduction to the following systems: Radar gun Remote Traffic Microwave Sensor (RTMS) GPS based vehicle navigation Priority Vehicle Detection Weigh In Motion (WIM) sensors  In depth instruction on Inductive loop detection systems Computer vision based detection systems

10. 10 Nationwide Network of Data To a nationwide network of dataFrom Spots of data A Public Private Partnership: shared risk shared benefit shared contribution

11. 11 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?

12. 12 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.

13. 13 Intelligence Requires Data With good traffic data, we can make our control systems smarter than this. Image Source: http://www.cartoonstock.com/directory/p/pull_over_gifts.asp
