Developed and introduced a comprehensive transit data analysis dataset for the Prof-Drake-UMD/INST767-Sp25 repository, focusing on enabling analytics and machine learning features. The work involved curating and modeling a large CSV-based dataset containing routes, vehicle identifiers, timestamps, and prediction-related metadata. Emphasis was placed on establishing clear data schemas and robust project scaffolding to support rapid feature prototyping and facilitate cross-team collaboration. Leveraging data engineering and data analysis skills, the developer validated the dataset’s structure to ensure suitability for feature engineering and future ML experimentation, laying a scalable foundation for data-driven decision-making within transit system analytics projects.
