Y2K AND WNRO: IMPLICATIONS FOR TRANSPORTATION

The Y2K problem stems from the fact that many computing systems use a two-digit format for the year instead of four digits. On January 1, 2000, computing systems may shut down or recognize 2000 as 1900, creating further problems with other dates. The week number rollover (WNRO) problem of the Global Positioning System (GPS) will occur less than four-and-a-half months prior to the end of the century, on August 22, 1999. This is caused by the GPS time-keeping system, designed with a 1,024-week cycle beginning on January 6, 1980, which will roll over from 1,023 to 0. This article addresses the implications of these two problems on transportation systems.
