Smart transportation systems leverage technology to enhance the efficiency and safety of transportation networks. These systems utilize data from various sources, such as sensors, GPS, and traffic cameras, to optimize traffic flow, reduce congestion, and improve public transit services. By integrating real-time information and communication technologies, smart transportation systems can provide users with timely updates on travel conditions, enabling better decision-making. This not only enhances the overall travel experience but also contributes to environmental sustainability by reducing emissions and energy consumption.
