2. Overview • Weigh-In-Motion • Virtual Weigh Stations • E-permitting • On-board Vehicle Weight Sensors • Freight Peer to Peer (P2P) Program

3. Weigh-In-Motion • Weigh-In Motion (WIM) allows vehicles to be weighed at speeds from 5-80 mph. • WIM is commonly used for monitoring CMV weights for strategically placed enforcement efforts; and for targeting overweight vehicles for weighing on a static scale. • Efficiently weighs high numbers of vehicles in an unattended mode. • There are over 390 CVO installations in North America, including approximately 175 Ramp Systems, 115 Mainline Systems, and 100 additional WIM/AVI sites used for Pre-Clearance

4. Virtual Weigh Stations • Virtual Weigh Stations utilize WIM, remote monitoring systems, and vehicle recognition equipment where there is no physical weigh station • Can include use of vehicle transponders, license plate readers, DOT number reading, and/or wireless access to the data and images by roadside enforcement personnel. • Allows for enforcement on bypass routes and increased enforcement with limited personnel.

5. Virtual Weigh Station - State Examples • Indiana: • May, 2001: Virtual Weigh Station deployed • Several cases where significantly overweight vehicles were identified and impounded • June, 2002: FHWA Report No. FHWA/IN/JTRP-2001/09 published • Describes concept of using existing equipment to develop a virtual weigh station • Virginia and Vermont continue to use Weigh In Motion data collection sites to contribute to enforcement strategy • Kentucky • November, 2001: Deployed a Remote Monitoring System (RMS) with camera technology on evasion routes • January, 2003: Added Weigh-In-Motion (WIM) to the RMS to create a Virtual Weigh Station

6. Virtual Weigh Station– Federal Role? • Federal Role – Office of Freight Management and Operations • Monitor State usage, studies, and data analysis of VWS • Continue to recommend VWS as an effective, efficient, and labor friendly tool in size and weight enforcement • Look for potential collaborative projects with states • Anything else? • Are there any standards that should be considered? • Should there be a coordinated national approach to deployment and can the FHWA and FMCSA help on this?

7. E-permitting • Electronic permitting (E-permitting) of oversize and/or overweight loads allows for wireless (and paperless) data transfer from the permitting agency to the roadside. • Electronically attained permits not only improve the efficiency and timeliness of the permitting process, but when used in conjunction with real-time enforcement efforts and bypass systems, also improves timeliness and efficiency of freight mobility.

8. 4 Levels of E-permitting Capability • On-line permitting available for drivers • Electronic permit data available to roadside enforcement officers • Permit data downloaded to State CVIEW database for verification and tracking purposes • Permit data sent from State CVIEW to SAFER and/or used for real-time screening of CMVs (Ex. Red light/green light type systems utilizing DSRC)

9. National E-Permitting Capabilities • FHWA Surveyed the States, of the 32 who replied: • 24 have Level 1 E-permitting in place, and 5 are in the planning process to initiate • 21 have Level 2 E-permitting in place, and 3 are in the planning process to initiate • 4 have Level 3 E-permitting in place, and 3 are in the planning process to initiate • 1 has Level 4 E-permitting in place, and 6 are in the planning process to initiate • Other government roles on E-Permitting?

10. Other Technologies - On-board Vehicle Weight Sensors • How they work: • Engine and transmission ECU’s used to estimate GVW by monitoring torque/speed curves on accelerations. • Monitor air bag pressure and vehicle ride height at each axle to determine the gross weight and load distribution of the vehicle. • Load cells mounted at the axles and fifth wheel to directly measure vehicle weights. • Use and Accuracy: • Commercially available systems have been proven under operational conditions to 0.5% to 1% accuracy. • Commercially available systems are also integrated with the truck's own in-dash display and any off-board communications devices. • Position and motion sensors may be applied for loads to detect movement of cargo during operation. • Government Role on Technology like this?

11. Freight Peer to Peer (P2P) Program • The FHWA’s Freight Peer to Peer Program provides: • information sharing between public sector freight transportation professionals and • free short-term technical assistance on an as-needed basis regarding freight planning and operations. • Contact: • Phone: 888-FRT 4 YOU • Email: FreightPeerExchange@fhwa.dot.gov • Online: http://www.ops.fhwa.dot.gov/freight/fpd/p2/index.htm

12. Current Activities - What else is needed? • Work with FMCSA to develop a national model for States interested in linking E-Permitting to expanded CVISN • Continue to recommend VWS as an effective, efficient, and labor friendly tool in size and weight enforcement • Monitor State usage, studies, and data analysis of VWS • Look for collaboration on VWS • Conduct International Scan looking at various size and weight technologies • Provide the opportunity for States to work with other States in setting up size and weight enforcement systems through the Freight Peer-to-Peer Program • What are other expectations for these subjects on S&W?
