Mark IV Industries provides most of thetags and readers for the US weigh and toll stations including PrePass, NORPASS, and E-ZPass which use the CVSN protocol. These tags operate in the 915MHz frequency using a proprietary air interface. In the Southeast, several toll agencies use TransCore’s RFID equipment. The USDOT is trying to eventually migrate all local state toll systems to a new international IEEE standard called 802.11p.

In the Southeast, several toll agencies use TransCore’s RFID equipment. The USDOT is trying to eventually migrate all local state toll systems to a new international IEEE standard called 802.11p. a single system to bypass weigh stations and roll through toll collection booths using E-ZPass, Fast Lane (in California), Pikepass (in Oklahoma), and SunPass (in Florida).
The 802.11p standard is not expected to be ratified until April 2009 and will use the 5.9GHz frequency. Mark IV, Genzo, TransCore, and others are prototyping compatible 802.11p products, but it is expected that the 802.11p infrastructure will not be deployed until at least 2012.
Currently there would be a lot of value opening these toll systems to commercial transportations companies to help them track their intermodal cargo.
