e-Governance in smart cities refers to the use of digital technologies, particularly information and communication technologies (ICT), to improve the efficiency, transparency, and responsiveness of government services. In the context of smart cities, e-Governance plays a critical role in managing urban infrastructure, optimizing resources, and enhancing the quality of life for citizens while promoting sustainable development. The integration of technology into urban governance enables cities to address complex challenges related to population growth, resource scarcity, and environmental sustainability. One of the key aspects of e-Governance in smart cities is digital service delivery. Governments leverage online platforms and mobile applications to provide a wide range of public services, such as paying utility bills, registering properties, obtaining permits, and accessing health and education services. By shifting services to digital platforms, cities reduce the need for physical visits to government offices, thereby saving time, reducing travel-related emissions, and minimizing administrative costs. Digital services also enhance transparency, as citizens can track the status of their requests, reducing the scope for corruption and inefficiency. Data-driven decision-making is another critical component of e-Governance in smart cities. Through the deployment of sensors, IoT devices, and other monitoring technologies, cities collect real-time data on traffic flow, energy consumption, air quality, water usage, and waste management. This data is processed and analyzed to identify patterns, forecast demand, and make informed decisions. For instance, traffic management systems use real-time data to optimize signal timings and reduce congestion, while smart grids monitor energy consumption to balance supply and demand efficiently. These practices contribute to sustainable
