The concept of smart cities incorporates technology to improve urban living and infrastructure efficiency. By integrating IoT devices, data analytics, and real-time monitoring, smart cities optimize public services like transportation, energy management, and waste disposal. Technologies such as smart sensors can monitor traffic and environmental conditions, allowing for dynamic responses to challenges. Additionally, citizen engagement can be enhanced through mobile apps providing relevant information. Ultimately, the goal is to create sustainable living environments that prioritize quality of life and reduce resource consumption.
