RFID Toll Plaza and Weight and Hight Measurement

Introduction

The RFID Toll Plaza with Vehicle Weight and Height Measurement is designed to automate vehicle identification and toll collection while monitoring vehicle dimensions and weight. The system uses RFID technology to identify registered vehicles and sensors to measure vehicle height and weight. By combining automated identification, measurement, and control, the project demonstrates how smart toll systems can improve traffic flow, reduce manual work, and support road safety.

Objectives

  • To automate toll collection using RFID technology.

  • To identify registered vehicles wirelessly.

  • To measure vehicle weight and height.

  • To detect vehicles exceeding configured limits.

  • To reduce manual intervention at toll plazas.

  • To improve toll management and traffic efficiency.

Methodology

  • Install an RFID reader at the toll entry point.

  • Attach RFID tags to registered vehicles.

  • Integrate a load cell with a suitable amplifier to measure vehicle weight.

  • Install height-detection sensors to measure vehicle clearance.

  • Connect the sensors to a microcontroller for data processing.

  • Display vehicle identification, weight, height, and toll status.

  • Operate a barrier using a motor or servo mechanism.

  • Test vehicle identification and measurement accuracy using a controlled model setup.

Instrument List

  • Arduino or ESP32

  • RFID Reader Module

  • RFID Tags

  • Load Cell

  • HX711 Load Cell Amplifier

  • Ultrasonic or Laser Distance Sensor

  • LCD Display

  • Servo Motor or Barrier Motor

  • Motor Driver Module

  • Buzzer

  • Toll Monitoring Software

  • Regulated Power Supply

Working Principle

When a vehicle approaches the toll plaza, the RFID reader scans its tag and sends the identification data to the controller. The system checks the vehicle's registration and toll status. A load-cell system measures the vehicle's weight, while a height sensor estimates its vertical clearance. The controller compares these measurements with configured limits and displays the results. Based on the RFID verification and toll status, the barrier can open automatically or remain closed. Vehicles exceeding the specified height or weight limits can trigger an alert for further inspection.

Advantages

  • Automated vehicle identification

  • Faster toll processing

  • Vehicle weight and height monitoring

  • Reduced manual workload

  • Automatic barrier control

  • Improved traffic management

  • Early warning for oversized vehicles

Conclusion

The RFID Toll Plaza with Vehicle Weight and Height Measurement demonstrates how RFID, sensors, and automated control can be integrated into a smart toll management system. It can improve vehicle processing efficiency while identifying vehicles that may require additional inspection. Accurate real-world weight measurement requires a properly engineered weighing platform, and height measurement requires suitable sensor placement and calibration. The prototype should be tested carefully before being considered for official toll collection or vehicle compliance enforcement
