State Of Alaska ~ Digital Roadway Data
February 14th, 2018
Mapping
Matters
We collect data on topography, soil
composition and environmental
conditions, both on and offshore. We
organize the acquired data and add
value through processing,
interpretation and visualization.

AUTOMATIC ROAD ANALYZER (ARAN)
Alaska – 2017
www.fugro.com11
ARAN POSITIONING DATA: GPS & DMI
• System: Applanix
• Internal Measurement Unit (IMU)
• Dual GPS 12-channel Antennas
• The DMI, mounted on the left rear
driving wheel, utilizes a precision
optical shaft encoder
• Accuracy: ±0.02% of the linear
distance traveled

ARAN HIGH DEFINITION: RIGHT-OF-WAY (ROW) VIDEO
• 3 Sensor Broadcast Quality Cameras
• Continuous Imaging at Various Intervals
• Wide angle HD images (Field of View 90°+)
• Shutter speed, 1/1000 of a second, to capture crisp image at
posted roadway speeds

LESSONS LEARNED - TBD
Gravel Roads
• Remote locations with poor cell coverage
• Loose stones can damage ARAN equipment
• ARAN is a 2wd vehicle that could get stuck in soft muddy areas
• Is there a spot for the ARAN to turn around at the end of routes?
What to do?
• Design cover for front enclosure to protect roughness lasers from loose gravel
• Equip crews with satellite phones to ensure they don’t get stranded
• Use a 4wd truck for collecting gravel/dirt roads
