SRS
Introduction
1.1 Purpose: Purchasing train tickets accomplishes a number of vital tasks that make traveling by train easy. The first benefit of buying rail tickets is that they enable people to reserve a spot on a particular train for a specified day and time. Passengers' travel is made more comfortable and crowding is prevented with the help of this reservation system. Passenger flow is also managed with the use of this reservation system. There are further financial benefits to purchasing rail tickets in advance. A cost-effective option for travel is offered by the several train companies that offer discounts and special pricing for early ticket bookings. Travelers can benefit from these affordable offers and reduce their trip expenses by making earlier plans and buying their tickets. Purchasing train tickets also saves travelers time and the boarding procedure. Travelers can board the train quickly and easily if they have a pre-purchased ticket, as it removes the need to wait in large lines at the station. Particularly for major routes where there is a large demand for tickets, this convenience is especially helpful during peak travel seasons. It has also become even more accessible and convenient to purchase rail tickets online or through mobile apps. Travelers now have flexibility and ease in arranging their trips with the ability to purchase tickets from the comfort of their homes or while on the go. Additionally, seat selection tools, rapid booking confirmations and a range of payment choices are provided by online ticketing systems, which improves passengers' overall travel experience. In the end, we can say that with the help of the system, customers should be able to easily reserve train tickets, pick their desired seats and complete payments online. In order to guarantee that the system is scalable, safe and easy to use, both functional and nonfunctional needs will be included. Knowing how important it is to buy train tickets will help passengers make wise choices that will improve their overall experience traveling by train.

1.4 Product Scope: User Management: Permit users to register, sign in, and edit their profiles, which include payment options, personal data, and travel preference, offering safe ways to authenticate (password, OTP, or biometric, for example). Users who are not registered can reserve tickets without requiring an account. Also provide users with an interface where they can see their account information, saved preferences, and upcoming and prior trips. Ticket Booking and Reservation: Permit users to provide the origin, destination, date, and time while searching for trains. The available trains with schedules and available seats should be returned by the system. Customers are given the choice to choose from a variety of seat selections, including regular, first-class, and other possibilities. Ticket costs are determined automatically based on the distance traveled, the class of the seat, the time of booking, and any available discounts (e.g., for seniors, students). The system gathers the pertinent passenger data (name, age, ID, etc.) needed for ticketing. Offer choices for printing physical tickets using station kiosks, or for creating e-tickets or QR codes for smartphone check-in. Payments and billings: Accept a range of payment methods, including bank transfers, UPI, digital wallets, debit cards, and credit cards. Install fraud detection software and secure payment channels with encryption. Automatically generate receipts and send an email confirming it, after a successful payment. Users are allowed to cancel their tickets in accordance with the operator's policies, and automatically receive a refund or credit when necessary. Ticket Management: Subject to availability and operator rules, enable consumers to view their bought tickets, modify their travel dates, or upgrade their seats. Customers are allowed to cancel their tickets and offer partial refunds, travel credits, or refunds in full. Notify users by email, SMS, or app notifications of any changes, such as delays, cancellations, or platform changes. Train Schedules and Real-time Information: Give passengers real-time train monitoring, including with the train's current location, estimated arrival time, and departure time. Provide trip planning tools that make recommendations for routes, stops for transfers, and approximate travel durations. Inform passengers automatically of any changes to the schedule or disruptions and offer suggestions for alternatives when appropriate. Customer Support: Establish a help desk with tutorials, FAQs, and instructions for creating and handling tickets. Provide chatbots or human customer support representatives to address complicated questions, grievances, or ticketing problems. Get input from travelers about their experiences with the train service or booking process. Connectivity with Outside Systems: Achieve real-time updates and accurate scheduling by ensuring the program interfaces with national or regional railroad databases. Encourage integration for ticket reselling and package sales with other sites, such travel agencies. Guarantees transaction processing compatibility with various payment gateway providers. Safeguarding and Adherence: Guarantees that sensitive data (payment, personal information) is encrypted, and that the system conforms with data protection rules (e.g., GDPR). Provide explicit privacy guidelines and methods for obtaining user consent before collecting or processing data. Utilize barcode, RFID, or QR code scanning to integrate with conductor apps or station gate systems for ticket validation.
