To improve the positioning accuracy of non-RTK GPS from meters to centimeters using V2X communication.
- Build an accurate base-map using data collected from the MTC Pillar 1 project.
- Query Safety Pilot Model Deployment and Pillar 1 data.
- Develop algorithms to improve positioning accuracy based on multiple vehicle GPS information and the base-map of the road network.
- Test the algorithms on smartphones and demonstrate their potential application to pedestrian safety in Mcity.
- Validate the approach in the Pillar 1 living laboratory.
- Algorithms to improve non-RTK GPS position accuracy from a few meters to a few centimeters.
- Methods and tools for near real-time GPS signal correction.
- Algorithms to perform batch update of the GPS signal in the “Connected Ann Arbor” database.
- An I2V and smartphone-based app to provide accurate pedestrian localization.
- Demonstrated pedestrian safety applications.
