Introduction

The RTC Ticketing System Using GPRS Communication is an intelligent embedded systems project developed to automate ticket generation and real-time fare management in public transportation. The system uses GPRS (General Packet Radio Service) technology to transmit passenger and ticketing information from the bus to a centralized server. This enables transport authorities to monitor ticket sales, bus locations, revenue collection, and operational efficiency in real time.

Unlike traditional paper-based ticketing systems, this project minimizes manual errors, reduces revenue leakage, and provides accurate digital records. The integration of GPRS communication ensures that ticketing data is securely transmitted over the mobile network, making the system suitable for modern smart transportation solutions.

Project Overview

The RTC Ticketing System consists of a microcontroller-based ticketing unit integrated with a GPRS modem, LCD display, keypad, thermal printer, and centralized database. Conductors can issue tickets by selecting the destination or fare using the keypad. The ticket details are displayed on the LCD, printed instantly, and simultaneously transmitted to the central server through the GPRS network.

The server stores the ticket information for revenue tracking, passenger analysis, and fleet management. This real-time communication helps transport authorities monitor bus operations efficiently without relying on manual data collection.

Working Principle

The system begins when the conductor enters passenger information or selects the travel destination through the keypad. The microcontroller calculates the fare based on predefined fare tables stored in memory. After confirming the transaction, the system prints the ticket using a thermal printer.

Simultaneously, the GPRS modem establishes a mobile data connection and sends ticket details such as ticket number, fare amount, bus identification, route number, conductor ID, and timestamp to the central server. The server updates the database instantly, allowing transport officials to monitor ticketing activities in real time.

If network connectivity is temporarily unavailable, the system stores the data locally and automatically uploads it once the GPRS connection is restored.
