Design and Implementation of a Metro Station Management System

Abstract

A modern metro station is a complex environment in which ticketing, passenger movement, train information, maintenance, and security have to work together. In practice, these activities are often handled through separate systems, which can make information sharing slow and increase the amount of manual coordination required from station staff. This paper presents a Metro Station Management System that brings six operational areas together on a common platform: QR-based ticketing with distance-based fares, passenger-flow monitoring, train scheduling and live arrival information, staff and maintenance management, CCTV-linked security alerts, and an administrative dashboard. The proposed system uses React and Node.js for the web application, MySQL for persistent data, and IoT-based sensors for occupancy monitoring. A relational database was selected to maintain consistency among ticket, fare, entry, and audit records. The design focuses on three critical operational paths—ticket validation, duplicate-scan prevention, and alert delivery—with target response times of less than one second for gate validation and less than five seconds for dashboard alerts. These targets are design objectives rather than physical-hardware measurements at this stage. The paper also discusses the current limitations, particularly sensor accuracy, network dependence, and the prototype's single-station scope.
