Featured project

CabLink – MTA Bus Delay Prediction & Taxi Alert System

A team of four is building an ETL pipeline that processes 15.5M GTFS-Realtime vehicle positions from AWS S3 and integrates five data sources (20M+ rows) into a unified hourly panel to measure bus delays. The team benchmarked OLS, Ridge, LASSO, SARIMAX and XGBoost models under time-ordered validation, delivering a calibrated XGBoost classifier with ROC-AUC of 0.802. A rule-based alerting layer flags stop-level transit disruptions so taxi drivers can capture stranded passenger demand.
