Project Description:

The Smart Toll Collection System is an IoT and web-integrated solution designed to automate toll payments on highways using RFID or ANPR (Automatic Number Plate Recognition) technology. It eliminates the need for manual cash transactions, reduces traffic congestion at toll booths, and ensures accurate and fast toll collection with digital records.

Key Features:

1. RFID/ANPR-Based Vehicle Detection:

   • Vehicles fitted with RFID tags or recognized via number plate cameras

   • When vehicle passes through toll gate, system reads tag/plate and triggers payment

2. Automatic Toll Deduction:

   • Prepaid user wallets linked to vehicle IDs

   • Amount auto-deducted based on vehicle type and distance

3. IoT Integration:

   • Barrier gate automation using microcontroller + sensors

   • Gate opens only after successful toll deduction

4. User Portal / Mobile App:

   • View balance, recharge wallet, transaction history, travel logs

   • Real-time alerts (SMS/email) for each toll transaction

5. Admin Dashboard:

   • Monitor daily collections, traffic reports, fraud detection

   • Manage users, toll booths, and pricing structure

Technology Stack:

• Frontend: HTML, CSS, JavaScript, Bootstrap

• Backend: PHP / Java / Node.js

• Database: MySQL / MongoDB

• Hardware Components (IoT):

  • RFID Reader (e.g., RC522)

  • ESP32 / Arduino / Raspberry Pi

  • Servo Motor for barrier control

  • IR Sensors for vehicle presence detection

  • Camera (for ANPR-based system)
