WVDOT GIS Status Update
• Created Web-based Applications• STIP• Proto-type Crash Analysis • Port Locations
Other Information Systems evaluated and considered for GIS integration;
• Road Inventory Log (RIL)• Project Tracking System (PTS)• Average Daily Traffic (ADT)• Pavement Management• Document Management• Coal Resource Tracking Systems (CRTS)
WVDOT GIS Status Update
• GIS Maps Developed:•Project Tracking System•Port Locations•Fuel Locations•HPMS Sample Locations•Homeland Security
Types of GIS-T Data Models
3 Main Types• Network Models
• Connections between links and nodes; i.e. TIGER
• Process Models• Concerned with how activities are
conducted; i.e. UTPS Travel Demand Models• Object Models
• Identifies many transportation objects as possible and logically organize them; i.e. Enterprise GIS
Types of GIS-T Object Models
3 Main Types• Centerline-based Models• Carriageway-Based
Models• Lane-Based Models
