HI-TRAC® TMU4

Highly accurate, high-speed traffic data collection system for weigh-in-motion and vehicle classification that does not interrupt to traffic flow and monitors up to 16 traffic lanes.

  • Support automatic enforcement of overloaded vehicles with toll by plate and weight
  • Integrate with ANPR, CCTV, height-width-length laser scanners, diversion signs, and WIM back office
  • Interface real-time traffic, weather, and environmental information

Overview

One of the main goals of governments and traffic authorities is to stimulate sustainable, safe transportation while preserving infrastructure. Weigh-in-motion solutions collect road usage data without disrupting traffic flow, while monitoring and enforcing fair and sustainable use.

The HI-TRAC® TMU4, an extremely accurate, high-speed traffic data collection system, detects, counts, and classifies vehicles while also providing weigh-in-motion capabilities. Without interruption to traffic flow, it records vehicle classification, axle load, and gross vehicle weight data that can be used for:

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

The system supports up to 16 lanes of multiple array configurations. The sensors and inductive loops are permanently installed in the highway. And as a result of the minimal investments in installation and maintenance, the agency incurs significant cost savings. It interfaces with multiple sensor types including piezo-polymer, piezo-quartz, strain gauge, and in-road temperature probes.

The system uses Q-Free’s advanced loop profiling techniques, which results in improved vehicle classification accuracy. In addition, advanced automatic temperature compensation algorithms significantly improve the accuracy of weight data.

The HI-TRAC TMU4 provides affordable high-end functionality with embedded Ethernet and TCP/IP stack, VPN, and FTP as well as 8GB data storage. It integrates with automatic license plate recognition (ALPR/ANPR) and CCTV cameras as well as traffic signals or diversion signs to intercept overloaded vehicles.
