The Complete Handbook of Toll Collection Devices

You have a fleet of 40 trucks crossing three states daily, and each state has a different toll tag. Or you run an access-control system for a parking operator who wants to accept toll transponders as a payment method. Or you are an IT consultant who just landed a contract to maintain the tolling equipment on a regional bridge network and need to learn the hardware fast. In all these cases, the device on the windshield is the least of the problem—the specs, the standards, the enforcement cameras, the billing disputes, and the battery chemistry all have a say in whether your operation runs smoothly or eats into your margins.

This handbook strips away the marketing material and gives you the working details. It compares the three major technologies—dedicated short-range communication (DSRC), automatic number-plate recognition (ANPR), and Global Navigation Satellite System (GNSS) tolling—and explains how they coexist. It covers the specific frequencies (e.g., 5.9 GHz for DSRC), the standards bodies that govern interoperability, and the reasons a plastic tag from one agency might beep or fail on another corridor. It addresses installation realities, such as why a metallic-tinted windshield is your enemy and where exactly to mount a tag for optimal read rates.

Beyond the hardware, the book covers the money. It examines the wholesale market for devices, the maintenance contracts that keep roadside readers alive, and the emerging business opportunities in reselling, servicing, and private-labeling tags. It finishes with a look at the regulatory and market trends—multi-protocol readers, GPS-based tolling for trucks, and the push for open-standard systems—and provides a glossary and FAQ for day-to-day reference.
