Integrating RS into Transportation Information Systems Val Noronha University of California, Santa Barbara
Why this engineering stuff? • Methodological research • DOT as customer: GI-science brings operational efficiencies • Academics (social scientists) as end-users: facilitates DOT data, e.g. access, safety • Hands across the sea: idea exchange
Environment Infrastructure Flows Hazards 4 universities 4 TAPs Background U.S. DOT — NASA Partnership Transportation Legislation “TEA-21”
NCRST Philosophy • Rapid evolution of research into commercial products, practice • User consultation and outreach • Partnerships: industry, international
Needs analysis Sensor technology Education & outreach Image processing tech Analysis/process model Data models, communication Research Production Line Problem Sensor Decision/solution Image processing Data integration Data management
NCRST—Infrastructure • Asset management (esp. location referencing) • ITS • Corridor/facility location • Security

Early Thinking • RS is not a monolithic solution; many types of imagery many approaches • No centerline solution is the “right” answer for all needs; each addresses a niche • scale • rural vs urban • Initial plan: validate RS with GPS
Material classification Edge detection Imagery Resources AVIRIS Spectral resolution Landsat TM IKONOS Soft copy photogrammetry Spatial resolution
Lessons Learnt • There are many approaches • No RS centerline solution is the answer to all our needs; each addresses a niche • Manual process with some automation, or largely automated process with some user intervention
GPS for Hwy Ops Hi end Lo end compatibility
Centerlines from RS — conclusion • RS not a fully automated solution … yet • Augments other methods (e.g. GPS) effectively, esp. visual verification • Good for small areas: 1:5K soft-copy photogrammetry • Good for large areas, 1:50K to 1:100K … global databases, sustainable policy, etc • Research is promising, worth pursuing
