The Q-Free HI-TRAC® TMU4 is a best-in-class high-speed traffic
data collection system that leverages artificial intelligence for
unrivalled accuracy. The single device supports up to 16 lanes
of multiple array configurations using AI loop signature analysis
combined with piezo electric axle measurements.
Without impeding traffic, the HI-TRAC TMU4 collects vehicle
count, occupancy, and speed data that is used for everything
from appyling for federal funding to enforcing weight limits.
A fallback design ensures reliable data. If a sensor fails, it is
supported by all remaining working sensors or loops. This
exclusive design feature enables customers to retrofit existing
sites without replacing in-ground sensors to deliver accurate,
reliable data in an affordable, scalable system.
