OREGON GREEN LIGHT PROJECT
Project Name: Oregon Green Light Commercial Vehicle Pre Clearance Systems
IRD Contract #: 1477
Client Name: Oregon Department of Transportation
End User: Oregon Motor Carrier Transportation Division
Value of Contract: $20 Million USD
Date of Award: August 1995
Date of Completion: January 2003
Location: Across the state of Oregon
Project Description: The Oregon Green Light Pilot Project was initiated in 1995 to deploy automated pre-clearance weigh stations designed to improve the enforcement effectiveness of existing weigh station facilities. IRD has designed, supplied, and installed each of the 22 weigh stations in partnership with the Oregon DOT.
A typical Oregon Green Light enforcement facility includes a pre-clearance/sorting system on the mainline employing weigh-in-motion (WIM) scales, and pole-mounted automatic vehicle identification (AVI) readers that interface with State computer databases. The pre-clearance system is capable of checking the compliance of commercial vehicle configuration, axle weights, and the credential records related to vehicle specific registration, tax payments, and safety as the vehicle approaches the weigh station. Upon processing the vehicle information, the driver is signalled with an in-cab device to either bypass (green light), or report (red light) to the weigh station.
The vision of the Green Light Project is to automate commercial vehicle operations in the State of Oregon. This includes automating truck inspection stations along the two interstate corridors, the primary highway system, and both the secondary and county systems. The Green Light Project is a national prototype model for the electronic preclearance of commercial trucks.
