What We Do… • Intelligent Transportation Systems • Transportation Data Archiving • Data Visualization Techniques • User Interface Design • Serious Games Development • Data fusion, interpolation, and forecasting • Incident Management • Traveler Information
Our Challenge
• Our Challenge: Make ALL of this data easily accessible and understandable to end users…
• Our data comes from these and others:
• And it includes: • Traffic Detector Data • Event/Incident Data (very detailed) from transportation operations centers
• Weather radar, forecasts, and alerts • Police Accident Reports (MD only)
