Highway Data Vehicle (DHDV)
(To see the above image animation, you need to
install Java Runtime)
The Digital Highway Data Vehicle (DHDV) includes the capabilities of the
Automated Distress Analyzer (ADA), rutting survey, inertial laser
based longitudinal pavement profiling and roughness measurement, pavement
right-of-way imaging, and positioning data collection.
In addition, WayLink provides users a comprehensive
application interface for accessing all data sets collected and analyzed with
the data collection devices, the Multimedia based Highway Information System
- Full-lane width distress survey of pavements at speeds of
up to 60mph (100 Km/h) and processes cracking data in real-time with
ADA with laser based imaging sub-system for
shadow-free image collection. ADA can also be used offline in
- Full-lane width Rutting Measurement, using accurate lasers that can
detect ruts down to 1-mm depths.
- Longitudinal profiling system to present longitudinal roughness, and
calculate International Roughness Index (IRI), Ride Number (RN), and
Macrotexture (MT) values, in accordance with the ASTM standards.
- Pavement Right-of-Way imaging system, with
digital color cameras to capture imaginary of roadway and roadside
structure. Varying camera options are available, including 1080p
High-Definition (HD) cameras.
- Positioning System Array consisting
of a differential GPS receiver, DMI, and a multi-axis solid-state Gyroscope.
User also can select high-precision Inertial Measurement Unit (IMU).
- Multimedia Highway Information System (MHIS),
application designed to dynamically display the DHDV-produced data
sets in a descriptive, visual, and flexible user interface. The
deluxe version of MHIS allows user to manually edit and add various
distresses defined through LTPP, MicroPaver, and others.
