Introduction

Urban air quality prediction is a critical area of research due to its significant impact on public health and environmental management. This project proposal aims to develop a predictive model for urban air quality using advanced machine learning techniques, drawing inspiration from recent studies that highlight the integration of environmental and urban activity data for accurate forecasting.

Background

Recent advancements in artificial intelligence and sensor technologies have enabled more precise predictions of air quality by considering a variety of environmental factors and urban activities. A notable study proposes a multi-modal framework that integrates real-time data from environmental sensors and traffic density information, demonstrating improved accuracy in predicting the Air Quality Index (AQI) through machine learning models.

Project Objective

The primary objective of this project is to develop a robust predictive model for urban air quality that leverages multi-modal data sources. The model will aim to accurately forecast AQI levels in urban areas and identify correlations between air quality and urban activities such as traffic patterns.

Methodology

1. Data Collection and Preprocessing

  • Datasets: Utilize publicly available datasets such as the "Air Quality Data in India" from Kaggle for training and evaluation.
  • Data Sources: Integrate data from environmental sensors, weather stations, and traffic density extracted from CCTV footage.

2. Model Architecture

  • Multi-modal Framework: Implement a framework that combines data from multiple sensors and stations using Particle Swarm Optimization (PSO) and Long Short-Term Memory (LSTM) networks for accurate AQI prediction.
  • Correlation Analysis: Analyze the correlation between traffic volume and air pollutants using data from CCTV cameras installed at key urban locations.

3. Training and Evaluation

  • Training: Employ ensemble learning methods to train models on distinct weather patterns, capturing both spatial and temporal dependencies.
  • Evaluation Metrics: Assess model performance using metrics such as Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and accuracy.

Expected Outcomes

The proposed system is expected to achieve high accuracy in predicting urban air quality by effectively integrating diverse data sources. The model should provide actionable insights into the relationship between urban activities and air pollution, aiding city planners in implementing effective pollution control measures.

Conclusion

This project aims to advance urban air quality prediction by developing an innovative model that integrates multi-modal data sources. By leveraging state-of-the-art machine learning techniques, the system is anticipated to offer significant improvements in forecasting accuracy and contribute to sustainable urban management practices.
