The Hawkeye 2000 Gipsi-Trac Geometry Package is a system that uses dead-reckoning sensors and a GPS receiver to collect road geometry information for continuous 3D highway maps.
The package, generally purchased as part of a Hawkeye Network Survey Vehicle, includes the Gipsi-Trac microprocessor based system which records and combines inertial data from gyroscopes, accelerometers and a distance sensor with GPS position.
The built in dead-reckoning allows for position data to be recorded when in tunnels, under bridges and locations with little or no GPS coverage. The system produces a survey database of WGS84 and road geometry data which can be used in conjunction with the other Hawkeye systems and exported to a pavement management system or other databases.
As well as being included in a Hawkeye 2000 Network Survey Vehicle, the Gipsi-Trac Geometry Package can also be purchased as a standalone product.
Applications:
- Provides road geometry and position for complex 3D highway mapping
- Estimate speed and travel times
- Advisory signage for road users
- Locate potential sites for rainfall ponding
- Conformance to design specifications
