Ministère de l'Écologie, du Développement durable et de l’Énergie The French National Projet : Using WIM for direct enforcement of overloading Victor Dolcemascolo – DGITM* Bernard Jacob - IFSTTAR** * General Directorate for Infrastructure, Transport and the Sea ** French Institute for Sciences and Technology for Transports, Development and Networks

2 Presentation plan  Introduction : Static enforcement of overloading  Description of the WIM project  Organization – Technicals means  Budget  Participation of the vendors

3 Static enforcement of overloading : Situation in France Yearly static controls

4 Static enforcement of overloading : Drawbacks and advantages  Need human resources (weighing officers, policemen...)  Need a static weighing area  Need static scales (risk of vandalism...)  Capacity to control only a small percentage of the truck traffic flow  Increase of the truck traffic flow and the average level of truck overloading → not efficient → but static weighing or low speed WIM are the ONLY devices legally approved for weight enforcement (by OIML recommandation)

5 Description of the WIM Project  4 years project :  IFSTTAR/ CETE Est and Ouest  Objective: Implementation of HS-WIM for direct enforcement of overloading  2 phases :  Phase 1 ( ): feasibility study for OIML type approval of an HS-WIM system  Phase 2 ( ): construction and test of a prototype

6 Organization WP1: Feasibility of OIML type approval WP4: Bridge WIM WP3 : MS-WIM Transv WP : On site test WP2 : Interaction sensor/pavement WP5 : Expert study

7 Technical mean: Accelerated Pavement Testing Facility

8 Budget  First phase ( ): 777 k€  Consumables, etc.: 177 k€  Staff: 600 k€ (50 MM)  Second phase ( ): 728 k€  Consumables, etc.: 150 k€  Staff: 578 k€ (48 MM)

9 Participation of Vendors  Welcome in this project  to take part in the experimentations  to contribute to and benefit of the R&D effort  to develop market solutions and products  IFSTTAR will issue a document describing the conditions of participation to this project (participation contract) + organise meetings Contact persons:
