OVERSIZE/OVERWEIGHTPERMITTING, ROUTING,
MONITORING
2
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

3
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

4
BACKGROUND

• 2006 European Scan Tour
• Emerging technologies
• Unconventional procedures
• Novel data applications
• Innovative funding mechanisms
• Multinational harmonization

5
EUROPEAN APPROACH

• Technology-based Policies/Procedures
• Self Permitting/Routing
• Switzerland provides self-routing Website
• Bridge Safety Assessment
• France, Slovenia use measured structureresponse,
  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
8
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
9
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
10
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
11
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
