Worked on the SANDAG/ABM repository to enhance airport model input data and calibration processes, focusing on improving simulation accuracy and data integrity. Applied Python scripting and data modeling to update input distributions and time period definitions, ensuring alignment with model horizons. Developed calibration assets and visualizations using Tableau and JavaScript to support trip length and mode share analysis, and updated mode choice coefficients for more accurate transportation modeling. Addressed data validation by implementing a fix to guarantee input shares sum to one, preventing calculation errors. The work emphasized data governance, reproducibility, and reliability for transportation planning and scenario analysis.
