HI-TRAC® TMU4

Highly accurate, high-speed traffic data collection system for weigh-in-motion and vehicle counting and classification that does not interrupt traffic flow.

  • Monitor up to 16 high-speed traffic lanes
  • Collect and interpret data for effective traffic network management
  • Integrate with a variety of sensors, devices, and systems

Overview

One of the main goals of governments and traffic authorities is to stimulate safe, sustainable transportation while preserving infrastructure. Automatic vehicle count and classification solutions as well as weigh-in-motion solutions collect road usage data without disrupting traffic flow while monitoring and enforcing fair and sustainable use. In addition, it can help transportation agencies make more informed decisions to improve road safety and traffic flow as well as make data-driven decisions for infrastructure planning and improvements.

The HI-TRAC® TMU4 offers extremely accurate, high-speed traffic data collection for detecting, counting, classifying, and/or weighing vehicles without interruption to traffic flow and monitors up to 16 traffic lanes.

When utilized for automatic vehicle counting and classification (AVC) and statistical data gathering, the system can:

  • Count and classify a variety of vehicles
  • Record the pattern of highway traffic for traffic flow optimization
  • Provide event monitoring as well as incident and queue detection

When used for weigh-in-motion (WIM), the system can record vehicle classification, axle load, and gross vehicle weight data that can be used for:

  • Highway traffic loading
  • Overload detection
  • Prescreening for vehicle enforcement

In addition, agencies and authorities can also leverage the data collected by the HI-TRAC TMU4 for predictive maintenance, environmental impact assessments, and transportation planning.

How does it work?

The well-established HI-TRAC TMU4 provides integration flexibility. It can interface with multiple array configurations using a variety of unobtrusive, in-road piezo-polymer, piezo-quartz or strain gauge sensors and inductive loops permanently installed in the highway as well as ANPR, CCTV, height-width-length laser scanners, diversion signs, and WIM back office – depending on your use case scenario. As a result of the minimal investments in installation and maintenance as well as interoperability with third-party devices, the agency incurs significant cost savings.

To achieve highly accurate and reliable results, the HI-TRAC TMU4 utilizes a variety of intelligent methods for both AVC and WIM applications. Using advanced algorithms, agencies can achieve upwards of 99.5% volumetric detection rates. Q-Free’s advanced loop profiling techniques also improve vehicle classification accuracy. In addition, sophisticated automatic temperature compensation algorithms significantly improve the accuracy of weight data.

The HI-TRAC TMU4 provides affordable high-end functionality with either modem or Ethernet communication options and 8GB standard memory to maximize data storage. It includes embedded Ethernet and TCP/IP stack, VPN, and FTP. In addition, it is NTCIP 1206 and OPCUA compliant.
