Big data analytics plays a transformative role in the development and optimization of public transportation systems within smart urban energy and transportation frameworks. As cities evolve into smarter and more connected environments, the integration of data from multiple sources—including sensors, GPS, mobile devices, social media, and fare collection systems—has become crucial for enhancing decision-making. Big data analytics enables transit authorities to process vast amounts of real-time and historical data to streamline operations, reduce energy consumption, improve service delivery, and ultimately enhance the user experience. One of the most critical contributions of big data analytics is in demand forecasting and route optimization. Transportation systems traditionally relied on static schedules and periodic surveys, which often resulted in mismatches between service supply and passenger demand. With big data, real-time passenger counts, weather conditions, and special event data can be analyzed to predict ridership patterns. This allows for dynamic scheduling and resource allocation. For instance, Transport for London (TfL) uses Oyster card data combined with GPS and traffic flow data to adjust bus frequency based on real-time passenger demand, reducing wait times and improving passenger satisfaction. Another major application is in predictive maintenance. Public transportation systems are complex and infrastructure-intensive. Delays and service disruptions often result from mechanical failures that could have been prevented. Through big data analytics, transport authorities can monitor the health of critical assets such as buses, trains, rail tracks, and signaling systems. Sensors installed on vehicles transmit data about engine performance, brake systems, and other components. Using predictive models, this data can alert maintenance teams before a failure occurs.
