Vertical Clearance
Coordination and Next StepsAMSC Update
August 29, 2013
Coordination Across ODOT
• Vertical Clearance – Good example of
• Criticality • Challenges
Coordination Includes
• AMI• Bridge Section• Freight Mobility Unit• Motor Carrier Transportation Division• Traffic/Roadway Section• Transportation Data
Mobile Scanner Test Results
• Able to measure vertical clearance on – Bridge structures– Pedestrian structures– Major traffic structures
• “Optimistic” measurement trend continued
• Data mining still a mystery– How as well as resource implications
Questions/Issues to Solve
• Vertical Clearance Measuring System (VCMS)– Technologically, no longer supported– Functionally, can only be used for bridge-type structures
• Meet needs for routing over-dimension vehicles– Process for all structures over highway
• Role of mobile scanner– Can be used for all structures, but unknowns for use on bridges
• Need reliable methodology
• Transition from old technology to new– Coordination and communication
• Compiling and maintaining– Resourcing
Next Steps
• Convene work group• Draft methodology for using mobile
scanner on major traffic structures– Must include data model for inventory and
attributes• Test methodology and process• Analyze and recommend
