  6. Course Schedule

  7. Course Schedule

  8. Course Requirements • There is no final exam for this class • Grading is based on • your class participation • the assigned moderator job • research paper/thesis abstract and references • Student moderators need to • introduce the speaker • distribute a representative paper of the speaker to the class for reading before the speech • raise questions and moderate the discussion

  9. About Myself

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

  11. Why? From the Bureau of Transportation Statistics, National Transportation Statistics 2009

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

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

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

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

  16. 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

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

  18. 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?

  19. 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.

  20. 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

  21. Provide the Best Traffic Operations • CEE 590 Traffic System Operations (Traffic System Control and Simulation) • Traffic Control Systems • Traffic Operations • Simulation Application Software • Vissim
