As the world’s urban population continues to swell, cities are grappling with the challenge of managing traffic flow effectively. Conventional traffic management systems often rely on centralized data processing, which can lead to delayed response times and inefficient resource allocation. Edge AI, on the other hand, offers a promising solution by processing data in real-time, at the edge of the network. In this article, we’ll delve into the world of edge AI for traffic management, exploring its benefits, applications, and potential impact on urban mobility.
