The public transportation system in Tamil Nadu is dominated by Tamil Nadu State Transport Corporation (TNSTC) and is complemented by railways and airways. TNSTC's public transportation system has low operational efficiency along with real-time passenger information. Passengers are left in the dark and not knowing when their transit will arrive at the stop results in longer wait times and lower quality of service. To address this issue, we propose a full-fledged web-based Transport Management System (TMS), which provides passengers with improved real-time updates for travel schedules for buses, trains, and air transportations in the State of Tamil Nadu. The proposed system will make use of Internet of Things (IOT) devices (e.g., GPS modules) that will be installed on TNSTC public transportation buses to extract the real-time location of TNSTC buses. The real-time location data would then be processed on the cloud and displayed for use by each passenger in an easy-to-use responsive website and mobile application. A single, comprehensive database would source initial, verified schedules of arrival/departure and include real-time status updates of TNSTC buses for easy accessibility to passengers. By using this proposed Transport Management System (TMS), passengers will be able to view the actual arrival and departure schedule of TNSTC buses, involvement in planning of multi-modal transit routes, and receive alerts specific to transit service. The main objective of this paper is to thoroughly examine and discuss the architecture of the proposed system, outlining the current limitations and issues of current methods for passengers, and ultimately, demonstrating how the proposed TMS enhances transparency in the operation of public transportation services for transit authorities and improves service quality for public transport passengers with timely, accurate, and accessible travel information
