Cloud-Based Local Train Ticketing System

Introduction

In an era where convenience and speed are paramount, the ticketing systems for local trains are ripe for an upgrade. Our cloud-based local train ticketing system aims to revolutionize how commuters book and manage their tickets, all while providing a scalable and efficient solution.

The Problem with Traditional Ticketing Systems

Current ticketing systems often rely on outdated methods that slow down the booking process and can result in long queues during peak hours. With our cloud train ticketing system, we aim to streamline this process, making it more efficient for both commuters and administrators.

How it Works

The cloud-based system allows users to register for an account, which then generates a unique ID. Once registered, users can book tickets for the western, central, and harbor lines of the local train network. Fares are calculated based on the distance between stations, and the user’s account balance is automatically updated. The cloud infrastructure allows the system to efficiently handle a large number of simultaneous users, offering quick and precise fare calculations.

Key Features

• Admin Account: The admin can manage user accounts and recharge balances upon request.
• User Registration: Users can easily create an account with a unique ID.
• Real-time Fare Calculation: Fares are calculated in real-time, allowing for efficient bookings.
• Account Maintenance: All account balances are maintained securely in the system.
• Versatility: Users can book single or return tickets for multiple lines.

The Benefits

By leveraging cloud computing power, the system offers:

• Quick and seamless bookings
• Ability to handle high traffic
• Reduced waiting times at stations
• A more environmentally friendly digital approach

Conclusion

As urban populations grow and the demand for efficient public transportation systems rises, our cloud-based local train ticketing system offers a timely and effective solution for both commuters and administrators.

Sample Code

pip install Flask

from flask import Flask, request, jsonify
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///users.db'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(50), nullable=False)
    balance = db.Column(db.Float, default=0.0)

db.create_all()

@app.route('/register', methods=['POST'])
def register():
    data = request.json
    new_user = User(username=data['username'], balance=0)
    db.session.add(new_user)
    db.session.commit()
    return jsonify({"message": "User registered", "id": new_user.id})

@app.route('/recharge', methods=['PUT'])
def recharge():
    data = request.json
    user = User.query.filter_by(id=data['id']).first()
    if user:
        user.balance += data['amount']
        db.session.commit()
        return jsonify({"message": "Recharged", "new_balance": user.balance})
    else:
        return jsonify({"message": "User not found"}), 404

@app.route('/book_ticket', methods=['POST'])
def book_ticket():
    data = request.json
    user = User.query.filter_by(id=data['id']).first()
    if user and user.balance >= data['fare']:
        user.balance -= data['fare']
        db.session.commit()
        return jsonify({"message": "Ticket booked", "new_balance": user.balance})
    else:
        return jsonify({"message": "Insufficient balance or user not found"}), 400
