OBJECTIVE

To improve the positioning accuracy of non-RTK GPS from meters to centimeters using V2X communication.

APPROACH

  1. Build an accurate base-map using data collected from the MTC Pillar 1 project.
  2. Query Safety Pilot Model Deployment and Pillar 1 data.
  3. Develop algorithms to improve positioning accuracy based on multiple vehicle GPS information and the base-map of the road network.
  4. Test the algorithms on smartphones and demonstrate their potential application to pedestrian safety in Mcity.
  5. Validate the approach in the Pillar 1 living laboratory.

OUTCOMES

  1. Algorithms to improve non-RTK GPS position accuracy from a few meters to a few centimeters.
  2. Methods and tools for near real-time GPS signal correction.
  3. Algorithms to perform batch update of the GPS signal in the “Connected Ann Arbor” database.
  4. An I2V and smartphone-based app to provide accurate pedestrian localization.
  5. Demonstrated pedestrian safety applications.
