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


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


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


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

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


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
