Example : The “Healing Horizon” mixed reality therapy help dementia patients with cognitive and muscle function recovery using personalized monitoring.

• 5G and C-V2X: The city is exploring 5G-enabled Cellular Vehicle-to-Everything (C-V2X) applications, allowing vehicles to communicate with each other and infrastructure to improve safety and reduce congestion

Example: Hong Kong's etoll system. Drivers can pass through the systems and reduces disruption to traffic flow. The fee will be automaticlly deducted from the user.

It helps traffic planners test the impact of different traffic management strategies, road designs, and signal timings before implementing them in reality.

Example: Smart Traffic Management Operation (STMO) in Kwun Tong

After over a year of trials, the police reduced their personnel from over 40 to about 6, maintaining or improving results with 80% fewer officers.

Method: Demand Management via AI-

Driven Electronic Road Pricing

Example:On a typical weekday at 8:15 AM, the AI system detects rapidly building congestion on the approaches to the Central-Wan Chai Bypass and the Western Harbour Tunnel, while the Eastern Harbour Tunnel is relatively clear.

The AI algorithm instantly increases the ERP charge for the congested Western Harbour Tunnel route from a base rate of $20 to a peak rate of $40. Simultaneously, it slightly decreases the charge for the less-congested Eastern Harbour Tunnel route to $15 to attract a portion of the drivers.

Example: Zero Carbon Building, which uses building-integrated PV, geothermal cooling, and real-time energy monitoring. Serves as a living lab for green tech.

Example: It optimizes police patrols for clearing illegal parking by deploying squads one at a time along designed routes, reducing bottlenecks, with collaborations with police, data was collected and combined with the DISCO system to study the dynamics on the roads scientifically, like how long will it takes for officers and traffic wardens to finish a round of patrol, warning off all the drivers parking in unauthorized spots? And how long would it take for those cars to return?

Example: LED Public Lighting Replacement Programme - Installed LED lamps in public lighting systems achieving over 83 million kWh energy savings since launch

Example: A pilot project for a real-time phytoplankton species monitoring system is being planned.The system collects real-time images of phytoplankton species in a fish farm area and uses artificial intelligence to classify the phytoplankton species. This data, along with other hydrological data, is used in a red tide risk prediction model. Currently, the system can identify 25 species of phytoplankton associated with red tides.

Example :the I·PARK facilities for processing food waste into energy, the I·PARK which incinerates sewage sludge to generate electricity, and landfill gas projects that convert methane from landfills into electricity or green hydrogen.
