Transcript Permitting, Routing and Monitoring

OVERSIZE/OVERWEIGHT
PERMITTING, ROUTING, MONITORING
CURRENT CHALLENGES
Significant Growth in CMV Traffic
• Increased congestion and delay
• Demand for larger and heavier vehicles
• Mounting stress on infrastructure
• Greater need for effective and efficient enforcement
CURRENT CHALLENGES
Personnel Limitations
• Permit review, approval, and issuance
– Labor-intensive and time-consuming
– Prone to human error
• Enforcement of permit authorization
– Ineffective, inefficient
– Accelerated infrastructure deterioration and damage
BACKGROUND
2006 European Scan Tour
• Emerging technologies
• Unconventional procedures
• Novel data
applications
• Innovative funding
mechanisms
• Multinational
harmonization

EUROPEAN APPROACH
Technology-based Policies/Procedures
• Self Permitting/Routing
– Switzerland provides self-routing Website
• Bridge Safety Assessment
– France, Slovenia use measured structure
response, traffic data
• Remote Field Verification of Permits
– Slovenia, The Netherlands
compare in-field
measurements to
permit on file
SUPPORTING TECHNOLOGIES
• Overheight Vehicle Detection System
• Vehicle Profiler System
• WIM Systems
– In-road
– Bridge
• Dynamic Calibration Vehicle
• Vehicle Identification System
• Advanced Routing/Permitting System
• Archived Records Database
SUPPORTING TECHNOLOGIES
Advanced Routing/Permitting System
Functions
• Allows drivers to self-route based on origin, destination,
route restrictions
• Requires supporting highway, bridge information
Considerations
• Initial development costly due to different state fees,
routing, regulations
• Provides 24/7 access for industry
Estimated Cost
• $2.0 – $8.3 million per statewide system
SUPPORTING TECHNOLOGIES
In-road WIM System
Functions
• Measures and records axle, gross weight using
piezo quartz, piezo ceramic, fiber optic sensors
• Provides 24/7 monitoring
Considerations
• May be less accurate than traditional WIM systems
• Low cost supports wider implementation
• $9,000 - $32,500 per lane
Estimated Cost
• Varies by sensor type, on-site communication requirements
• Requires additional, ongoing maintenance with associated
costs
SUPPORTING TECHNOLOGIES
Bridge WIM System
•
•
Considerations
•
•
Estimated Cost
Requires suitable bridge and location
Most successful on short, stiff bridges
Structural assessments require transducer calibration
Calibration may require specialized expertise
• $100,000 - $130,000 per bridge/system
• Varies by sensor type, on-site communication requirements

Strain (V)
Functions
• Measures, records weight using existing structures
instrumented with strain transducers/gauges
• Measures, records axles using traditional sensors or
Nothing-on-Road/Free-of-Axle Detector (NORFAD) systems

SUPPORTING TECHNOLOGIES
Vehicle Identification System
• Cameras capture vehicle silhouette, license plate images
Functions
Considerations
Estimated Cost
• OCR software converts license plate image to numeric data
• Images/data transmitted via DSRC to portable computer
used by enforcement officials
• Conversion of license plate images may result in errors
• $52,000 - $80,000 per system
• Varies by camera type, on-site communication requirements
SUPPORTING TECHNOLOGIES
Archived Records Database
• Supports data-driven enforcement scheduling
Functions
• Supports preventative carrier contacts
• Supports enhanced data quality
• Encourages long-term performance monitoring
Considerations
• Requires procedures for quality control
Estimated Cost
• $225,000 - $300,000
