DMI & Traffic Data Collection

Are you are looking for the most advanced Bluetooth traffic sensor like the Bluemac x7? Do you need to complete complex traffic counts with our NC-350 or Armadillo Tracker? Do you have to calculate distances for sign post or guardrail with the NiteStar DMI? Then Coral Sales has you covered!

Bluemac x7 Bluetooth Traffic Sensor

The Bluemac x7 captures more reads and matches for rich Travel Time and Origin-Destination data using the latest technology with cutting edge computing. It employs state-of-the art privacy protection to customer-owned, white box open data, and implements strong security protecting device and data access to only authorized parties and systems. The seventh generation x7 is flexible offering multiple configuration and customization options to meet varied customer needs and harsh deployment environments yet delivers the best total cost of ownership.


  • Three base configurations – solar powered self-contained, external installation, or mounted in-cabinet
  • Ethernet is standard, with Wi-Fi an available backhaul option along with 4G LTE NB-IoT or Cat-M1 cellular
  • Mains (both AC and DC), battery, or PoE for power sources
  • Mix and match the different device configurations across one deployment
  • Cloud hosted with option for on-premise server extension
  • Choose which combination of logging is right for the situation, any combination of BLE, Bluetooth Classic, and Wi-Fi



You Own Your Data

By default, you own the data at all levels produced by the Bluemac system, with privacy protection strongly applied on the raw and matched data. For customers in situations where they cannot own the data or can only use processed output, we work out the needed terms directly with each customer.


Latest Technology

The x7 is loaded with the latest in IoT technology, ensuring a long viable lifespan as part of any ITS infrastructure:

  • 1 GHz ARM processor with 2000 MIPS of processing power
  • 512MB of DDR3L 800 MHz RAM
  • Highest spec Bluetooth Classic 4.2 transceiver
  • Highest spec Bluetooth Low Energy 5 transceiver
  • Best in class Wi-Fi supporting 802.11b, 802.11g, and 802.11n
  • Available quad band 4G LTE NB-IoT / Cat-M1 Modem
  • Built-in Ethernet




More Matches, More Reads

With a “triple play” across Bluetooth Low Energy (BLE), Bluetooth Classic, and Wi-Fi, the x7 delivers the matches needed to produce sufficient measures even in low volume traffic, to quantify multimodal journeys, and the device reads needed for effective dwell calculations.



Bluetooth Low Energy (BLE)

While Bluetooth Classic remains the gold standard for quantifying vehicle Travel Time, Speed, and Origin-Destination by logging in-car entertainment systems, adding BLE delivers greater than 4 times more matches to supplement Bluetooth Classic captures. Privacy infringing techniques, such as logging non-discoverable devices, are not needed. BLE reads the new class of smart devices as well as previously undiscoverable smartphones for additional vehicle captures while still respecting the privacy settings of citizens.



Designed with Multimodal Travel in mind

Bluetooth Low Energy (BLE) also provides a superior means to quantify pedestrian, bicyclist, and transit / multimodal travel, with a demonstrated capability to log more than 40% of bicyclists and pedestrians based on a study done by Bluemac. If additional reads are needed, Wi-Fi logging is also supported. Customers can take advantage of the additional device captures delivered by Wi-Fi, especially helpful for dwell time metrics, yet still apply Bluetooth technology for superior Origin-Destination calculations – you get the best of both in one. The system is designed to allow a mix-and-match of logging means. Customers can choose to log only BLE, Bluetooth Classic, or Wi-Fi, as well as any combination of the three.





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.


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.
