Non-Intrusive Traffic Monitoring System (NTMS)
Description
The Spectra Research NTMS is a portable, accurate and non-intrusive
sensor for monitoring multi-lane traffic from the side of the
highway. The NTMS consists of two identical laser radar (LADAR)
channels (separated by 1.0 feet) contained in an enclosure which
serves as an optical platform and protects it from the elements. The
NTMS sensor emulates two road tubes or tape switches per lane for 1
to 4 lanes of traffic. The NTMS interfaces to the auxiliary port
(tape switch input) of an existing traffic monitoring device, such
as the Diamond Phoenix or equivalent device. The sensor is designed
to operate on the road shoulder, 12-15 feet from the nearest lane of
traffic. The sensor is non-intrusive and eliminates the need to
install road tubes, loops or tape switches within traffic lanes,
minimizing traffic delays and hazard to traffic engineers.
Status
S*R currently has two prototype units in ongoing field tests for the
purposes of demonstrating the technology and developing comparative
data.
A patent application is in progress for the dual-beam laser sensor
incorporated in the NTMS design.

LADAR Axle Detection System (NILAD)
Description
Spectra Research has recently begun a development program in
conjunction with the University of Kentucky Research Foundation (UKRF)
to develop a single channel, non-intrusive axle counter based on our
NTMS technology.
Status
This program is currently underway.

Profiler
Description
The Spectra Research Laser Pavement Profiler is a non-contact
optical measurement instrument which measures the distance to the
pavement surface with 0.0012 inch resolution over a measurement
range of 5 inches and at a rate of 64,000 samples per second. It is
suitable for acquiring both gross pavement profile and surface
texture information from a vehicle moving at speeds up to 60 MPH.
Status
Spectra Research is actively seeking partnerships with companies,
government agencies, universities and individuals with interest in
using or producing S*R laser pavement profiler technology.
