Road Geometry
Extremely cost-effective option for collecting geometry data
ROMDAS Road Geometry module is an extremely cost-effective unit, used to calculate and record pavement gradient, radius of curvature, cross-fall and other road geometry characteristics.
The unit uses an integrated GPS and MEMS Internal Measurement Unit (IMU) with a navigation, attitude and heading reference system processor. This combination provides accurate and reliable highway geometry data. The internal low-power signal processor runs a real-time Kalman filter providing inertial enhanced 3D position and velocity estimates.
Easy to install and setup, this Geometry module can be integrated into a ROMDAS System within an hour. A real-time output of vehicle Pitch, Roll and Yaw is displayed in the ROMDAS Data Acquisition Software during the survey. The software does not require any operator interaction during data collection.
All data is referenced with GPS coordinates for easy integration with most commonly used GIS mapping software or Pavement Management Systems (PMS).
