Presentation Transcript

  1. Application of Intelligent Transportation Systems (ITS) for Statewide Traffic and Evacuation Monitoring and Management in Louisiana April 16, 1999

  2. Who Are We? Louisiana State University • Department of Civil and Environmental Engineering • Dr. Marc Levitan, Structural Engineering • Dr. Brian Wolshon, Transportation Engineering • Remote Sensing and Image Processing Laboratory • Chris Schwehm, Digital Processing

  3. What is ITS? Application of Advanced Information and Communication Technologies for Transportation • ATMS - Video Surveillance, Incident Detection and Response, Adaptive Traffic Signal Systems • ATIS - Changeable Message Signs, HA, In-vehicle Information, Dynamic Route Guidance • CVO - Safety Assurance, Automated Credential Administration, Weigh-in-Motion • AVCS - Collision Avoidance, Road Condition Sensing, Advanced Guidance

  4. Limitations of Current Systems Used in Louisiana • Limited Statewide Traffic Data Collection • Limited to Hourly Volume and Average Speed • Not “Real-Time” • Not Easily Accessible and Usable • No Roadway Specific Weather Data • Road Icing, Fog Conditions, Wind Speed • Limited Coordination Between OEP & DOTD • Evacuation for Natural and Technological Hazards

  5. What Do We Suggest? • Collect Data Statewide • Traffic, Weather, Road Surface Conditions • Process this Information in Real-Time • Automatic and Immediate Updates • Make it Available • Use the World Wide Web • Decision Makers and the Public • Present information in a Clear and Useable Format • Graphical Interface (point and click)

  6. What Will It Do? If such data were available in an easily accessible form, it could have a tremendous positive impact on • Hurricane Evacuations • Incident Detection and Management • Traffic Management • Air quality attainment? • + many others

  7. System Requirements • Provide data on • Traffic • Road surface conditions • Weather conditions • Regional or statewide coverage of key routes • Provide data in real-time or near real-time

  8. System Requirements, cont’d. • Allow simultaneous access to all officials in need of the data • DOTD, OEP, State Police • Local counterparts • Provide feedback (management) capabilities • Allow public access to selected portions

  9. Problem Solution...
