Hong Kong Deploys 400 Smart Lampposts to Monitor Air, Traffic, Crowds

Causeway Bay/Wan Chai stands among four pilot sites for the Multi-functional Smart Lampposts Pilot Scheme. Roughly 400 units will gather live readings on air quality, traffic volumes and crowd movement.

Traffic signals join the data network

The Transport Department has started trials of adaptive traffic lights at connected junctions in Causeway Bay. Pedestrian and vehicle sensors adjust green-light times on the spot. These trials sit alongside the lamppost rollout and draw from the same data streams.

One Causeway Bay, the redeveloped site of the former Excelsior Hotel, already operates as a smart commercial building in the same district. Its systems align with the broader push for connected infrastructure under the Smart City Blueprint 1.0.

Street-level services expand

The first HKT Smart Kiosk opened in Causeway Bay. It keeps payphone functions while adding free Wi-Fi, USB chargers and local updates, including a dementia-support application. The kiosk forms part of a pilot to replace older phone booths with multi-purpose points.

Causeway Bay also receives targeted upgrades for pedestrian routes. Government mobile apps will carry expanded walking-path information to link routes across the district under the same Smart City Blueprint 1.0 framework.

Over 40 percent of major tech occupiers already sit in Causeway Bay. The lamppost and signal data can feed directly into planning tools used by those firms and by local coworking spaces such as Garage Causeway Bay.

Residents can check the new apps for walking options and use the kiosk services during daily movement through the area. Further junctions and lamppost sites will come online as the Transport Department and scheme operators complete installation stages already under way.
