2. Information Technology impact on society Impact on economy –Financial industry –Insurance industry –Entertainment industry (games) –Utilities Impact on science and engineering –Biology (bioinformatics, human genome project) –Environmental science (weather prediction) –High energy physics –CAD/CAM –Operations research –Mathematics

3. IT impact on Transportation

4. Car navigation systems, web-routing

5. IT impact on Transportation Car navigation systems, web-routing Traffic information systems (Nelson’s lab)

6. IT impact on Transportation Car navigation systems, web-routing Traffic information systems (Nelson’s lab) Autonomous/assisted driving (in area W/O traffic, sponsored by military),

7. IT impact on Transportation Car navigation systems, web-routing Traffic information systems (Nelson’s lab) Autonomous/assisted driving (in area W/O traffic, sponsored by military), Fleet management software (Mobitrac),

9. Traveler services and traffic management –Dynamic real-time routing –What is the average speed a mile ahead of me? –Are there any accidents ahead? –What parking slots are available around me? –Taxi cab: what customers around me need service? –Customer: What Taxi cabs are available around me? –During the past year, how many times was bus#5 late by more than 10 minutes at station 20, or at some station

10. Safety and security –Vehicle in front has a malfunctioning brake light –Vehicle is about to run a red light –Vehicle 100 meters ahead has suddenly stopped

11. IT trends => Transportation Wireless networking (wi-fi, wimax, UWB, 4G) –Cellular paradigm –Mobile P2P paradigm VANET MANET Mesh networks

12. IT trends => Transportation Sensor networks –Vehicular sensors: speed, fuel, cameras, airbag, anti-lock brakes –Infrastructure sensors: speed detectors on road, parking slots, traffic lights, toll booth

13. IT trends => Transportation Sensor information processing (static sensors) –Sensor fusion –Protocols for sensor networks –Detection/classification/tracking of phenomena –Distributed control and actuation

14. IT trends => Transportation Distributed and mobile computing –Fault tolerance, connectivity, longevity –Location based services –Energy and resource management –Programming models and languages Positioning technologies (GPS, cellular) Computer vision Information systems: –Spatial-temporal data management –Moving object databases Context awareness Multimedia data GIS Security, privacy (k-anonymity), trust management

15. CTS vision: System oriented approach Develop a platform for building them Platform = Software architecture + Interfaces + Tools that enables easily building applications

17. Prototype

18. ITA Intelligent traveler assistant – –on handheld computers –networked to Traffic information center Neighboring vehicles –plan multi-modal routes for its user

19. ITA modes Multi-modal trip planning –Possible optimization criteria: cost, time, predictability Trip execution (plan adjustment) – taxi/ride-sharing opportunities

20. Trip execution experiment 20 vehicles with ITA’s receiving sensor information in real-time demonstrate simple query processing in a mobile environment

21. Main differences from other transportation centers Focus on Computer Science and IT Focus on traveler rather than vehicular technology Focus on applications above communication layer
