Highway networking inches along: weigh stations, toll booths move toward interoperability

摘要

In this day of USB ports and standard protocols, you expect to be able to use electronic devices just about anywhere. But on the open road, interoperability among systems used to bypass weigh stations, collect tolls and cross borders remains a work in progress. Since early 2004, National Freight Inc. (NFI) has used a single system to bypass weigh stations and roll through toll collection booths. Each truck has a PrePass Plus transponder that communicates with roadside readers at weigh stations that use the PrePass system and with toll booths that use the E-ZPass toll collection system.
