  1. AGENCY-WIDE BENEFITS ------------------------------------------------------------------------------------COMMERCIAL MOTOR VEHICLESIZE AND WEIGHT MANAGEMENT

  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 • CMV Size and Weight Non-compliance • Premature pavement deterioration • Increased annual maintenance costs • State: $8 to $144 million • National: $265 million to $1.11 billion • Costly, time-consuming infrastructure repairs • Single events: $150,000 to $350,000 • Compromised safety levels • Traffic delays, fuel consumption, harmful emissions

  4. CURRENT CHALLENGES • Bridge Infrastructure Deterioration • 72,500 U.S. bridges “structurally deficient” • $65.3 billion repair estimate • Inexact methods to reduce, refine, prioritize actions • Uncertainties in traffic loading • Uncertainties in bridge response

  5. CURRENT CHALLENGES • Personnel Limitations • Inflexible fixed weigh facilities • Significant effort expended on compliant carriers • 1% violation capture rates on U.S. Interstates • Labor-intensive permit review, approval, issuance • Lack of coordination, integration, data sharing • Planning and programming • Enforcement • Design and engineering

  6. THE NETHERLANDS BELGIUM GERMANY FRANCE SWITZERLAND SLOVENIA BACKGROUND • 2006 European Scan Tour • Emerging technologies • Unconventional procedures • Novel data applications • Innovative funding mechanisms • Multinational harmonization

  7. EUROPEAN APPROACH • Unique Partnerships • Similar agencies of different jurisdictional levels • National and regional law enforcement agencies • Different agencies • Transportation, law enforcement, regulatory, and prosecution agencies In The Netherlands, the Ministry of Transport funds 100 additional limited capacity National Police Agency officers who focus 40% and 60% of their time on weight enforcement and congestion/incident management activities, respectively.

  8. EUROPEAN APPROACH • Technology-based Policies/Procedures • CMV enforcement • size • weight • WIM system calibration • OS/OW vehicle permitting, routing, and monitoring • Bridge infrastructure preservation

  9. BENEFITS • Higher volume of CMVs monitored, processed • More efficient use of personnel • Increased accuracies, certainty in court • Significant infrastructure damage cost savings • Reduced congestion, harmful emissions EUROPEAN APPROACH • CMV Size Enforcement • Infrastructure preservation • Switzerland, The Netherlands protect critical tunnels • Pre-selection for manual enforcement • Germany, combined with Toll Collect system • Direct enforcement • Switzerland, combined with fixed weigh facilities

  10. EUROPEAN APPROACH • CMV Weight Enforcement • Pre-selection for manual enforcement • Various countries, supports mobile and fixed operations • Enforcement resource scheduling • France, Slovenia, The Netherlands utilize historic WIM data • Preventative carrier contacts • France, The Netherlands target habitually non-compliant carriers • Bypass prevention • France, The Netherlands support site selection, site level system plans Pre-selection, enforcement resource scheduling, and preventative carrier contacts often combined to provide comprehensive enforcement approach.

  11. BENEFITS • Increased violation capture rates • Reduced fixed facility demand • Reduced harmful emissions from static weighing process • Significant infrastructure damage cost savings EUROPEAN APPROACH • Direct enforcement • France, The Netherlands leading efforts • Low-speed and high-speed WIM • Attaining sufficient WIM system accuracy levels • Gaining metrological certification • Modifying existing laws that require static measurements

  12. BENEFITS • Eliminates resource-intensive field calibration • Enhanced data quality benefits: • Planning and programming • Enforcement • Design and engineering EUROPEAN APPROACH • WIM System Calibration • Continuous calibration • France, The Netherlands, during scheduled enforcement • Quality assurance • The Netherlands issues QA Statement with every data request • Dynamic calibration • The Netherlands utilizes specially designed vehicle

  13. BENEFITS • Increased personnel efficiency, cost-effectiveness • Increased bridge safety accuracy • Increased permit violation capture rates • Significant infrastructure damage cost savings • Reduced congestion, harmful emissions EUROPEAN APPROACH • OS/OW Vehicle Permitting, Routing, and Monitoring • 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

  14. BENEFITS • Offers traditional WIM system capabilities • Cost-effective, non-intrusive data capture • More accurate structural/safety assessment • Supports “soft” load testing • Significant cost savings from appropriate rehabilitation • Reduced congestion, harmful emissions EUROPEAN APPROACH • Bridge Infrastructure Preservation • Structural/safety assessment • Slovenia, France enhance the accuracy of bridge safety conclusions through direct measurements • Load testing • Slovenia uses “soft” load testing

  15. 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
