Armadillo Tracker

The Armadillo Tracker is the world's smallest, fully integrated radar traffic counter. It can collect multi-lane, bidirectional traffic data statistics with its 97% traffic count accuracy and best-in-class 0.4% speed error accuracy. With its ultra-low battery consumption, the Tracker can run up to two weeks with its built in batteries. It can be used to collect traffic data for:

  • Traffic Studies before and after road construction projects
  • Traffic flows within a Shopping Mall, Event Space, Parking Structure and more
  • Track areas where vehicles are speeding to increase police presence
  • Annual Average Daily Traffic counts for City, County and DOT traffic studies

Start Collecting Vehicle Traffic Data in Minutes

With its small and compact size, and easy setup, the Armadillo Tracker is a non-intrusive traffic counter that also provides a safe installation since it does not require anything to be placed in the road, unlike traditional traffic tube counters. Watch the video below to see just how quickly the Armadillo Tracker can be collecting your Annual Average Daily Traffic (AADT). 



Additional Features

  • Radar-based traffic statistics collection device with target tracking
  • Collects individual time stamped vehicle counts, speeds, and class (up to 3) per direction in up to 2+2 lanes
  • Computes real-time, per direction average speed for incident detection applications
  • 0.4% speed accuracy and up to 97% vehicle count accuracy
  • On-board memory stores 300,000+ individual vehicles
  • Add-on options for a 5W solar panel and GPS for geo-tagging multiple locations

M.H. Corbin NC-350 Portable Traffic Analyzer

Replacing the NC-200 and NC-300 counters is the latest in portable in-roadway traffic analyzers, the NC-350. The NC-350 has been reengineered to include Bluetooth™ technology while still providing the same accurate count, speed and vehicle classification. Utilizing Vehicle Magnetic Imaging (VMI) technology, the new NC-350 traffic analyzer combines accuracy and portability, monitoring traffic flow conditions right where you need them.


  • Now Communicates wirelessly via Bluetooth!
  • NC-350 can be installed and removed in minutes
  • Inconspicuous design blends in with road surface
  • Individual vehicle recording allows infinite binning capabilities
  • Durable extruded aluminum housing
  • Long life, rechargeable, Lithium-Ion battery
  • Easy to use software for viewing data


The NC 350 Portable Traffic Analyzer is designed to survey traffic on roadways, bridges, parking garages, or construction areas. Because the analyzer can communicate wirelessly via Bluetooth, traffic data can be retrieved & downloaded without removing the analyzer from the road. The NC350 BlueStar Portable Traffic Analyzer with Bluetooth™ Technology from MH Corbin provides the accurate measurements of vehicle count, speed, and vehicle length. The NC350 BlueStar Portable Traffic Analyzer sensor is placed directly in the traffic lane to measure data, and can be installed and removed quickly and easily without damage to the road surface.


Connect Via Bluetooth™

Vehicle classification data and studies are now easily uploaded/download via Bluetooth™. Gone are the days of pulling the counter off the roadway in the middle of a study to see the data you have already collected. Easily upload new studies when moving your NC-350 to a different location. As Always data can be seen using the Highway Data Management (HDM) software for analysis.




HDM Software

MH Corbin’s Highway Data Management (HDM) software allows users to program, download, and query a variety of portable traffic classification units, including the NC90, NC97, NC100, NC200, and NC300 devices. Using HDM, traffic studies can be programmed, retrieved, combined, and re-binned per user preferences, and analyzed with a full range of supplied reports.

  • HDM has a simple and intuitive interface to allow users to quickly program and read portable traffic classification units. Settings are remembered so that multiple units can be programmed to the same study parameters.
  • Data can be collected in one or more catalog files, allowing users to easily archive and move data.
  • Studies can be trimmed, merged, or extracted into separate files or into existing studies.
  • Multiple reports and graphs are provided to show data in a variety of formats. Report data can be exported to a wide variety of formats include HTML, PDF and CSV files. Batch printing of reports is also supported.

HDM Software FAQ

The video below covers some of the most common questions related to the NC-350 HDM software.

M.H. Corbin Nitestar DMI

The Nitestar 50 & 60 are Distance Measuring Instruments (DMI) that accurately record distances and survey coordinates as you drive. Distances are used for logging points along a given route.  The Nitestar DMI’s are highly accurate.  They can be used in conjunction with a speed sensor device and are especially useful when used with an array of other data collecting and distance measuring tools. The Nitestar Distance Measuring Instrument is perfect for surveying and mapping data while also capable of understanding many distance distinctions.



  • Measurements are displayed in real-time
  • Displays distance intervals between points of interest
  • Extensive internal memory for data storage and export
  • Optional SDM software allows for easy organization for viewing and reporting collected data.
  • Inventory data and coordinates are stored in a single file
  • Customizable key definitions for user or application
  • Easy to install and use
