DHDV - PVision3D Application

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 (mhis).

Features

1, 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 office environment.

2, Full-lane width Rutting Measurement, using accurate lasers that can detect ruts down to 1-mm depths.

3, 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.

4, Pavement Right-of-Way imaging system, with multiple high-resolution, digital color cameras to capture imaginary of roadway and roadside structure. Varying camera options are available, including 1080p High-Definition (HD) cameras.

5, 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).

6, Multimedia Highway Information System (MHIS), a user-friendly 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.
