In Guangzhou’s historic Yuexiu District, the iconic banyan trees and arcades tell stories of the past—but so do the tangled overhead cables, long a headache for urban aesthetics and safety. With limited underground space, new traffic signals often relied on these "spider webs," especially at the busy Dabei Overpass intersection (Jiefang North Rd. & Huanshi Middle Rd.). 

This crucial hub connects major east-west and north-south routes, serving heavy pedestrian, bike, and vehicle traffic near Yuexiu Park (a 4A-grade scenic spot) and shopping districts. Adding bike signals seemed impossible without more overhead clutter—until ClairPLC’s two-wire solution came in. 

By transmitting signal data through existing power lines (no extra cables or road digging!), the tech cleared the skies, boosting safety and visual appeal. A win for smart cities!
