From smart roads to autonomous vehicles, transportation infrastructure now demands low-latency edge processing for vision, analytics, and safety systems. Real-time monitoring—such as license plate recognition, passenger flow analysis, and vehicle diagnostics—is becoming a baseline requirement. Traffic environments are often harsh, crowded, and mobile, driving the need for compact and ruggedized computing platforms. Connectivity standards are evolving fast, enabling instant broadcasting, synchronized displays, and high-bandwidth data transmission. Modular edge systems allow rapid deployment across buses, trains, airports, and roadside units without lengthy redesign cycles.
