Traffic Counters & Classifiers
IRD provides a full range of vehicle counters and classifiers. From the compact, yet versatile Mini ACE to the TRS Mini, Plus, and rack mounted vehicle classifiers, to the Tracker hand-held turning movement counter, IRD's traffic counter/classifier line-up has it all:
The Tracker hand-held counter allows the user to efficiently track 16 different turning movements through an intersection. The display is located in the center of the counter to allow all buttons to be easily accessed. The Tracker interfaces directly to the Road Reporter software (optional) for processing, reporting and storing data.
The 990 People Counter accurately detects and counts pedestrian traffic at specific points such as doorways and entranceways.
The Millennium Trail Traffic Counter is a portable, battery powered instrument for counting trail traffic in remote areas.
The Traffic ACE is designed to allow up to four inputs from a variety of sensors. The Standard 16-character LCD allows the user to view all four channels of data without the use of an external display. The Traffic ACE accumulates the total volume of vehicles for a specified period of time. The unit can simultaneously or independently collect volume, speed and axle classification data. Classification and speed data are collected into 14 bins each. Classification, speed and total volume data are all displayed on one screen.
IRD's Mini TRS can count up to 4 lanes. The standard four line by 20-character LCD display with 16 alphanumeric keys allows the user to program the unit without a computer. The TRS can be operated with the integrated keypad and display or by a serial link with a computer or modem. It is completely menu-driven for easy operation in the field.
IRD's TRS product line adds flexibility to traffic data collection.

The TRS WIM combines all of the features of the TRS traffic counter and classifier with the added function of Weigh-in-Motion (WIM), providing more in-depth information and data for your traffic planning. Data can be grouped according to classification, speed, time, or weight, depending on your needs.
The TMS-SA is a compact, portable non-intrusive vehicle counter/classifier that is ideal for temporary traffic studies. Using a Doppler radar, it counts vehicles, measures their speed and classifies up to four length categories.
The SAS-1 passive acoustic sensor system provides advanced technology for cost effective multi-lane "side fire" highway traffic monitoring for freeways and midblock applications.
The non-intrusive radar-based RTMS (Remote Traffic Microwave Sensor) G4 is an advanced sensor for the detection and measurement of traffic on roadways.
IRD offers a full suite of software to help you process and analyze your traffic data.
