Abstract

How the Original ISS Works (PDF, 24K)

The Inspection Selection System (ISS) was developed as part of the Aspen roadside inspection software system, in response to a 1995 Congressional mandate calling for the use of prior carrier safety data to guide the selection of vehicles and drivers for roadside inspections. The Aspen system includes software to help conduct roadside commercial vehicle/driver inspections with portable microcomputers, including hand-held pen-computers. Aspen includes electronic transfer of inspection results, and electronic access to carrier safety performance data and commercial driver license status data. The ISS algorithm was designed at the Upper Great Plains Transportation Institute, North Dakota State University, in cooperation with a ten-state Roadside Technology Technical Working Group and the Federal Highway Administration's Office of Motor Carriers (OMC). The OMC's Field Systems Group managed the overall project and completed the ISS and Aspen software development.

The main objectives of the ISS are to recommend roadside inspections for those commercial vehicles and drivers with:

1. Poor prior safety performance as evidenced by an unsatisfactory safety compliance fitness rating and/or higher than average vehicle/driver out-of-service rates
2. Very few or no roadside inspections in the previous two years relative to the carrier's size
