Coordination and Next StepsAMSC Update

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
