Why Road User Charging Systems Need a More Intelligent Distributed IoT Solution

Sierra Wireless

In addition to e-books, on-demand video and GPS devices, one of the future technological innovations envisioned by AT&T in its famous early 1990s series of “You Will” commercials was an Electronic Toll Collection (ETC) system that enabled drivers to wirelessly pay their tolls as they drove through a toll booth. While that prediction was perhaps not as bold as the others (Europe began developing similar ETC systems in the 1980s), today we take for granted E-ZPass in the U.S. and similar systems where drivers can enter toll roads, HOV lanes, bridges and tunnels without having to stop at a tollbooth to pay.

Typically, these systems require a driver to put an OBU (On Board Unit, which can be called transponder or “edge” IoT device) in their vehicle and, when their vehicle passes through a toll booth, the toll booth wirelessly connects to the edge to automatically deduct the toll from their bank account.
