Vital Protection
CERTIS can also help simplify the train installation of CBTC,
since the system doesn't require
odometry and RFID readers.
Elements of the CERTIS System
include a UWB antenna and the
control module, with the UWB
nodes installed in specific locations to create an overlapping and
redundant UWB network.
"Currently, it is actually more
expensive to install CBTC into a
legacy train car than purchasing
a new car which is pre-wired for
CBTC," Carlson said.
Because these systems can be
more affordable than traditional
CBTC, agencies can install CERTIS on MOW equipment or work
trains, adding an extra element of
safety for MOW workers.
"The modularity and cost
effectiveness of CERTIS allows
agencies to install UWB on their
MOW or work equipment and

integrate directly into the CBTC
system," Carlson said. "The modular design used in CERTIS also
introduces additional upgradable
capabilities such as UWB-based
worker protection, collision
avoidance, precision berthing,
track intrusion detection and
signal compliance."

A Portable and
Independent
Safety Solution

Another solution to address human error factors when it comes
to protecting roadway workers is
Miller Ingenuity's ZoneGuard,
an electronic RWP system that
detects vehicles entering a work
zone through redundant sensor
technologies and sends audible
and vibrating alarms to workers'
wearable devices, explains Christine Nestor, marketing communications specialist, Miller Ingenuity.

"The LIDAR, radar, infrared
camera and accelerometer work
together to ensure that track vehicles will be detected consistently and accurately," Nestor said. "It
also helps eliminate the chance of
false alerts, that when occurring
frequently, can give a false sense
of security or wrongfully establish
complacency among work crews."
Compared to older RWP systems, which require the installation of onboard components,
ZoneGuard can operate independently from onboard alert units
but can be included in the setup if
needed. ZoneGuard can also perform across several tracks, over
bridges, under high power lines,
in loud environments and through
curves and tunnels, where older
RWP systems can experience trouble in these scenarios, Nestor adds.
Agencies can choose between
the fixed or portable ZoneGuard
