A proposed AI City Brain could combine information on blocked drains, storm locations, traffic congestion and CCTV flood images to predict where serious flooding is likely and recommend which government departments should respond. The plan was outlined by Tang Ping-keung, the Secretary for Security, as a way to support decisions during extreme weather.
The system is proposed in the Policy Address, with its first phase estimated to cost about HK$200 million and targeted for completion in 2028. The phase would link data from works, environmental and transport departments on a shared electronic platform.
Tang said the platform would not gather new information from outside sources.
The flood-response function remains a planned capability, not an operating service.
At a Legislative Council security-panel briefing, legislator Dominic Lee Tsz-king asked how the system would guard against deliberate intrusion and data leaks. He also raised the possibility of AI systems interfering with other systems or attacking themselves.
Tang said critical-infrastructure protection and several layers of safeguards would be used. He described artificial intelligence as an analysis tool and said human officials would examine its recommendations before deciding whether they were feasible and reasonable.
