Transcript of 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
Considerations
• Requires supporting highway, bridge information
• 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
Considerations
• Provides 24/7 monitoring
• May be less accurate than traditional WIM systems
• Low cost supports wider implementation
Estimated Cost
• $9,000 - $32,500 per lane
• Varies by sensor type, on-site communication requirements
• Requires additional, ongoing maintenance with associated costs
SUPPORTING TECHNOLOGIES
Bridge WIM System
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
Considerations
• Requires suitable bridge and location• Most successful on short, stiff bridges• Structural assessments require transducer calibration• Calibration may require specialized expertise
Estimated Cost• $100,000 - $130,000 per bridge/system• Varies by sensor type, on-site communication requirements

SUPPORTING TECHNOLOGIES
Vehicle Identification System
Functions
• Cameras capture vehicle silhouette, license plate images
• OCR software converts license plate image to numeric data
• Images/data transmitted via DSRC to portable computer used by enforcement officials
Considerations • Conversion of license plate images may result in errors
Estimated Cost• $52,000 - $80,000 per system
• Varies by camera type, on-site communication requirements
SUPPORTING TECHNOLOGIES
Archived Records Database
Functions
• Supports data-driven enforcement scheduling
• 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

BENEFITS
• Increased personnel efficiency,cost-effectiveness– Georgia issues 99% of permits
within target two-hour time
• Increased accuracy in determining bridge safety
• Increased violation capture rates• Significant cost savings
– single prevented infrastructure impact– unnecessary or premature rehabilitation
• Reduced congestion, harmful emissions
