Presentation Overview Case Study / Problem Statement Review Asset and Data Collection Selection Method Data Collection Project Execution Digital Video Field Survey Digital Video Asset Extraction Benefits Other Uses
Case Study Regional Municipality of Halton, Ontario, Canada 967 square km Region / County Network Four local municipalities Population 2005 430,000 Regional Road System 312 Centre line km of Roadway 842 Lane Km of Roadway 212 Traffic Signals 167 Un-signalized Intersections
Problem Statement 2003 Transportation Services Department implements a Transportation Data Model (I.e. data dictionary) to maintain Infrastructure data for the Regional Road Network Right of Way DATA IS REQUIRED TO FUEL THE ENGINE Development and implementation of a process to determine what data is required and what is the best method for field data collection Cataloging existing data sources (paper/mylar/cad/gis) Reviewing Detailed Data Requirements Consultant Retention Data Gap Analysis Workshop with all users Establish rules/relationships/linear referencing Approach to execution of data collection
Transportation Data Model Assets and Data Collection Phasing Phase Asset Phase Asset 1 Guide Rail 2 Access 1 Intersection 2 Boulevard 1 Marking Line 2 Bridge 1 Marking Point 2 BusStop 1 Marking Poly 2 Curb / Gutter 1 Master Controller 2 Hand Hole 1 Median 2 Inlaid Delineater 1 Number Of Lanes 2 Landscape Area 1 Pole 2 Loop Detector 1 Sign Location 2 No Parking 1 Sign Placement 2 No Passing 1 Sign Type 2 No Stopping 1 Street Centreline 2 No Trucks 1 Street Light 2 No Turns 1 Traffic Controller 2 Pavement 1 Traffic Signal 2 Railway Crossing 2 Recreational Path 2 Road Speed 2 Sidewalk 2 Wall
Phase 1 Assets Data Collection Selection Methodology Data Requirements Complete, accurate (sub metre) and current geometry/attribute Integration with Transportation Data Model Reviewed data collection selection methods Digitization Handheld GPS Mobile Digital Video Survey Advantages and Disadvantages were compared
Data Collection Method Selection Method Description Data Sources Advantages Disadvantages Digitization Tracing/Digitizing Tablet On-screen Digitizing CAD Drawings/Mylar s/ Paper Maps / Orthophotography Labour costs Timeframe Data currency Positional accuracy Hand Held GPS Mobile Digital Video Imagery Field Data Collection In office data compilation Mobile Collection Digital Video Imagery / In office data extraction and GPS Data compilation GPS Unit/Field Staff Accuracy control Safety Resource intensive Weather/satellites Attribute collection Positional accuracy Attribute accuracy Immediate Inventory No field revisits Weather Cost of technology if purchased
Data Collection Method Selection Scoring Matrix A scoring matrix was established for each transportation infrastructure asset with respect to the data collection methods Code Rating 1 Not achievable 2 Intensive 3 Accom plishable 4 Good 5 Optim al m ethod Each asset was given a rating based on on the ability to capture the geometry/attribute requirements
