High-Cadence Dissemination of Signal Phase, Timing, and 3D Lane Topologies

Standardizing the digital representation of complex urban intersections for autonomous vehicles.

Sub-Decimeter 3D Lane Geometry Ingestion

MAP messages define lane boundaries, pedestrian crosswalks, and allowable turning radii with 5-centimeter geospatial precision.

SPaT packets broadcast the exact millisecond a green light will transition to yellow, enabling autonomous eco-driving and glosa optimization.
