Installation of commercial vehicle electronic screening systems, which began in the mid- 1990’s, is accelerating as more and more states become part of the Commercial Vehicle Information Systems and Networks (CVISN) program. Deployment of electronic screening is one of the requirements for achieving CVISN Level One compliance. Thus, many states are currently looking for an electronic screening system that can be used to meet their needs. Kentucky’s “Model MACS” system provides an attractive option for many of these states. The Mainline Automated Clearance System (MACS) was originally developed in the mid-1990’s for the Advantage I-75 Operational Test Project. That system was deployed at 29 weigh stations (in seven jurisdictions) and was evaluated from October 1995 through September 1997. Using the “lessons learned” from that operational test, the Kentucky Transportation Center (KTC), under the direction of the Kentucky Transportation Cabinet, undertook the development of a “next generation” system, which is called “Model MACS.” The functional requirements for the software were developed by KTC staff, and the software was developed by TRW, Inc. Model MACS was designed to be simple, flexible, low in cost, and non-proprietary. The software is owned by the Kentucky Transportation Cabinet, and it is being made available at no cost to any state that wishes to use it. It is a “drop-in” system, i.e., it can be added to an existing weigh station with no need to modify existing systems or develop complex interfaces. This paper provides some background on Model MACS, an overview of the development process, a physical description of the system, a discussion of required interfaces, a functional description, a brief look at the operator interface, a discussion of features and advantages, and a note on current status and availability. |
