What Are Smart Transportation Systems?

Smart transportation systems combine advanced technologies with infrastructure and vehicles to improve transportation efficiency and safety. They use sensors, IoT devices, real-time communication, and analytics to optimize traffic management, reduce congestion, and provide better travel experiences.

In simple terms, STS are intelligent ecosystems where roads, vehicles, and control systems “talk” to each other. This leads to:

• Real-time monitoring of road conditions
• Predictive traffic flow management
• Reduced emissions through optimized routes
• Safer roads through automated systems
