Green Light Success Story
• Now serving 4,100 companies with 40,900 transponder-equipped trucks.
• In 2006, weigh-in-motion and transponder systems at 22 weigh stations allowed trucks to avoid unnecessary stops a total of 1,353,591 times.
• Truckers saved $13,265,192 in operating costs, 112,800 hours of travel time.
• Green Light is on track to preclear its 8-millionth truck in April 2007.

Technological Conceptsfor
Preserving Bridges and other Weight Sensitive Roadways
– Virtual Weigh Stations• Fixed sites (either existing or new)
– Photo WIM• Portable sites
Virtual Weigh Stations
– Virtual Weigh Stations use Weigh In Motion (WIM) technology with a video capture system to collect images of vehicles exceeding size and weight limits.
– The system can store data for post-processing, or can transmit images immediately of potentially violating trucks to remote locations or mobile enforcement units.
– Virtual Weigh Stations use permanently installed sensors at either new or existing WIM locations
Photo WIM Concept– Same concept as Virtual Weigh Stations, with
the exception that the sensors may be portable, and installed temporarily, for practical use at bridge locations and other weight sensitive roadways.
– Images captured of overloaded vehicles for post enforcement efforts or immediate transmission to remote locations or mobile enforcement units.• Possible Civil Penalties• Due Cause for Additional Audit/Inspection

Web Based Virtual WIMVehicle data for Real Time or Post Enforcementactivity can begathered either by:
• date
• vehicle record number
Web Based Virtual System
To review information for a specific truck,
simply click on the image
Web Based Virtual System
The Vehicle Detailscreen provides a time-stamped recordthat includes:
• axle configuration• axle spacing• overall length• individual axle weight• tandem/tridem weights• total GVW• vehicle speed• any associated warnings
• A potential cause of damage to Oregon bridges is over-laden trucks. In additionto being a tool for enforcement, a Virtual System may also be used to warn drivers directly .
• By combining Virtual WIMwith existing Green Lighttechnology, warning systemscan be designed to redirecttrucks that may exceed a bridges’ recommended weight capacity

Assess the problem
From 2001 through 2006:
• Truck miles traveled increased 8%.
• Truck crashes increased 33% and the crash rate increased 23% — from 0.598 to 0.735 per million miles traveled.
• Truck-at-fault crashes increased 32% and the truck-at-fault crash rate increased 22% —from 0.323 to 0.394 per million miles traveled.
Truck-at-fault crashes have been increasing for several years.
Focus on the driverA 2006 crash causation study found that drivers of large trucks and other vehicles involved in truck crashes are 10 times more likely to be the cause of the crash than weather, road conditions, vehicle performance, and other factors.
Rally the partners
Law enforcement officers working under the Motor Carrier Safety Assistance Program (MCSAP) are key to the effort to reduce truck-at-fault crashes. State Police troopers take the lead, but 55 other agencies have non-compensated agreements and 33 actively perform inspections and other enforcement work.
Help enforcement officers
Safety specialists and enforcement officers must have ready access to safety information to effectively do their job. Oregon has its own remarkable tools – Real Time, Enforcer, OSCAR.
ENFORCER• Enforcer brings efficiencies to the job of weighing and
identifying trucks as they roll through• weigh stations or get precleared by Green Light weigh-
in-motion systems. At static scales,• it allows motor carrier enforcement officers to quickly
enter license plate numbers and then• collect each truck’s weight information. The software
also automates the citation process• by allowing officers to enter weight- or vehicle-related
violation details on the computer screen• and print a copy of the citation to hand to the driver.

Real Time software• Real Time collects the details of all enforcement
activities and makes that available to inspectors• and enforcement officers anywhere in the state. With
Real Time, officers can call up records• of citations, warnings, and scale crossings (weigh station
event data) for any specific period of• time. They can query the database by truck license plate
number or carrier file/authority number.• Inspectors routinely use this software when verifying a
driver’s logbook.

Oregon Truck Parking IssuesOregon Truck Parking Issues
Why do so many truckers spend the night parked on highway on- and off-ramps?
What’s the problem?
What’s the solution?
A 1998 report by the FHWA identified a problem at public rest areas
A check of 1,487 public rest areas on Interstate highways in 48 states, and direct observation of usage on a 200-mile segment of I-81 from Virginia to Tennessee found:
• Of truck parking available on the segment of I-81, 20% of spaces were in public rest areas and 80% were in truck stops.
• During the day, half of the rest areas were full or overflowing. At night, 8 in 10 were full or overflowing.
1998 report also notes other issues
• Trucks often park on Interstate shoulders and ramps to avoid parallel parking spaces that some drivers say are difficult to use.
• Truck parking capacity at rest areas is reduced by recreational vehicles and cars parked in truckparking areas.
• Approximately 42% of the 1,487 rest areas have a time limit on truck parking, but only 1 in 10 of these facilities report that the limits are “always” enforced.
1998 report – rest area vs. truck stop
• “. . . truck drivers tend to use rest areas for their short-term parking needs, and truck stops for long-term parking needs.”
• “. . . accessibility to parking facilities had some influence on driver choice of a place to stop. Drivers who value accessibility tended to prefer public rest areas.”
• “. . . safety features were positive attributes in explaining capacity utilization of truck parking spaces, and a major reason why drivers prefer truck stops.
A 2000 study by the NTSB identified a problem and called for further study
• “. . . not enough adequate truck parking spaces are available to accommodate traffic patterns in certain locations.”
• “. . . the lack of available truck parking or the truck drivers not knowing where parking would be available can negatively impact safety.”
• “Some truck drivers . . . need to be made aware of all available parking, both in advance of and during trips.”
A 2002 study mandated by TEA-21 confirmed supply / demand issues
• A shortage of parking at public rest areas may exist in 35 States and a shortage of total parking may exist in 12 States.
• A driver survey found 23% of the demand for parking is at public rest areas, but only 10% of the supply is there ― 50% said parking is rarely or almost never available at rest areas.
• The estimated growth rate of truck parking spaces at public rest areas is below the estimated growth in demand for these spaces.
But in terms of inventory, the 2002 study found adequate parking supply
“. . . parking areas for trucks and buses along major roads and highways are more than adequate across the nation when both public and commercial parking facilities are factored in.”
A 2003 Transportation Research Board report summarizes state actions
State strategies for managingincreasing parking demand:
• Expanding or improving public rest areas
• Educating or informing drivers about available spaces
• Making better use of the private sector and private truck spaces
“. . . most parking supply is located in commercial truck parking lots and plazas, and the overcrowding problem concentrates in public rest areas.”
