Mini TRS Plus Traffic Counter and Classifier

IRD's TRS product line adds flexibility to traffic data collection. The Mini TRS Plus traffic counter's standard 4-line by 20-character LCD display with 16 alphanumeric keys allows the user to program the unit without a computer. The Mini TRS Plus can be operated with the integrated keypad and display or by a serial link with a computer or modem. Completely menu-driven for easy operation in the field.

Versatile Mini TRS Plus traffic counters can be used for many traffic data applications. In the passive mode, they allow government agencies to collect data for congestion management, signal timing and planning. In the active mode, they meet a wide range of ITS requirements.

The Mini TRS Plus traffic counter has been updated with increased memory storage, flash upgradeable firmware, and USB ports.
