1. OVERSIZE/OVERWEIGHT PERMITTING, 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 THE NETHERLANDS BELGIUM GERMANY FRANCE SLOVENIA SWITZERLAND

5. 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

6. 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

7. 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
