IEM and Intelligent Transportation Systems
IEM develops, produces, and markets innovative imaging, optical and other sensor-based systems for safety
and
security applications in the intelligent transportation system industry. By combining innovative sensor
systems
with advanced software, IEM creates intelligent solutions for use in vehicle inspection, security
monitoring,
maintenance activities, and more. Founded in 1987 to manufacture and market our Electronic Wheel Gauge, IEM
has expanded its high-tech operations to all forms of transportation. IEM leverages research and development
for the Department of Defense and other government and industrial partners to develop core technologies.
Railroad Markets
IEM serves the needs of all railroad customers including freight, transit, and high-speed rail safety and
security
systems. From handheld gauges and yard-based inspection systems to wayside ‘super sites’ capable of
monitoring
rail cars up to 250 km/hr, IEM offers a suite of proven products and emerging technologies.
