This document summarizes a presentation about analyzing passenger data to understand passenger choice in boarding metro cars. It discusses using loadweight data from London Underground trains to analyze which cars passengers board at different stations. The analysis finds that approximately 55% of passengers make boarding choices based on their destination station, aiming to board cars closer to exits, while the other 45% base choices on boarding the car nearest their point of entrance. The document advocates developing frameworks to systematically analyze data and create value from understanding passenger behavior.
