Microscopic Traffic Safety Analysis and macro-level transportation analysis

Microscopic Traffic Safety Analysis

Leveraging Waymo dataset, I conducted a granular safety analysis by:

1. Visualizing agent dynamics (position, velocity, yaw) alongside road markings and boundaries.
   
2. Extracting lane geometries (IDs, shapes) to map connectivity.
   
3. Identifying conflict points at intersections.
   
4. Generating lane polygons for precise map-matching.
   

Macro-level transportation analysis

I conducted an Origin-Destination (OD) analysis using the Weijo dataset to examine daily travel patterns at the block group level, identifying key mobility trends, peak-hour congestion zones, and trip distribution dynamics.
