This study presents a real-time Malaysian road sign recognition system using computer vision. The developed system achieves high accuracy, enhancing driver safety through advanced artificial neural networks.

Area of Science:

  • Computer Vision
  • Artificial Intelligence
  • Road Safety Engineering

Background:

  • Driver support systems are crucial for road safety, with road sign recognition providing essential real-time information.
  • Accurate identification of traffic signs is vital for preventing accidents and ensuring compliance with traffic regulations.

Purpose of the Study:

  • To develop and evaluate a real-time road sign recognition system specifically for Malaysian traffic signs.
  • To enhance driver safety by providing timely notifications of road restrictions and hazards.

Main Methods:

  • A two-stage approach was employed: detection using a hybrid color segmentation algorithm and recognition using a novel custom feature extraction method.
  • A multilayer artificial neural network (ANN) was utilized for sign interpretation, tested on both standard and non-standard road signs.
