Data Vehicle (DHDV) contains the heart and soul of WayLink's
technologies. The vehicle, built on a heavy-duty truck chassis, such as Ford E-350, integrates
various sub-systems in an all-encompassing framework
Pavement Surface Imaging Model 4096 (APSI-4096)
conducts a full-lane width distress survey of pavements at speeds of up to
60 mph (100 Km/h) at 1-mm resolution, and process the data at real
time. It uses the laser imaging system to rid of shadows and provide
uniform and consistent high contrast pavement images during or or night.
Automated Distress Analyzer (ADA)
ADA is a product of many years of research and development. ADA is
capable of producing crack maps to identify types, geometries,
at 60 MPH
(100 Km/h). ADA was designed to conduct full cracking surveys at
real-time along with the APSI-4096
with images and analysis results saved into location referenced database
Right-of-Way Imaging System (PRIS)
This sub-system captures
imagery of roadway, pavements, signs, and other Right-of-Way features. Using multiple high-resolution, area-scan
color cameras, PRIS is able to produce images of unprecedented quality.
Camera options include baseline 1300-pixel color cameras, High-Definition
(HD) 1080p color cameras, and Ultra HD color cameras.
Highway Information System (MHIS)
user-focused application allowing for data review and editing in an office environment.
This application is designed to display all the data sets collected during a DHDV collection procedure.
More importantly, distress information can be easily edited and added into
the pavement database tables through the use of the deluxe version of MHIS.
Rut-Measurement System (LRMS)
Laser Rut Measurement System (LRMS) is a
transverse profiling system, capable of acquiring full 4 m (13ft 5in) width
profiles of highway lanes at speeds up to 100 Km/h (60 mph) at the
resolution of more than 1200 points.
Dedicated, high-frequency, high-intensity
lasers, for collecting
longitudinal roughness data for use in calculations of International
Roughness Index (IRI), Ride Number (RN), and Macrotexture (MT).
Systems Array (PSA)
Systems Corp. installs an array of positioning systems in DHDV to represent the vehicles speed, bearing, location, and other general
positioning data sets. This array consists of a heavy duty Distance Measuring Instrument (DMI); a self-contained,
differential GPS receiver and antenna. A solid-state, multi-axis, inertial
sensing Gyroscope, or a high-end Inertial Measurement Unit (IMU)
are the user selectable options..
