This study explores the integration of Remote Sensing (RS) technology into Transportation Information Systems to enhance operational efficiencies and safety. Methodological research conducted by Val Noronha at the University of California, Santa Barbara, reveals how RS benefits the Department of Transportation (DOT) as a customer, facilitates data access for academics, and enables idea exchange across four universities. The research delves into needs analysis, sensor technology, education and outreach, image processing, and data management, emphasizing partnerships and user consultation. The study highlights RS applications in asset management, location referencing, Intelligent Transportation Systems (ITS), security, and infrastructure mapping. Lessons learned underscore the diverse approaches in RS centerline solutions and the importance of validating RS with GPS for manual or automated processes. Engaging with various standards and partnerships, this research emphasizes the promising role of RS in transportation systems. Stay updated at ncgia.org for more insights.

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
