Data-gathering street lamps tested

Top News | Charlotte Luo 14 May 2019

The first 50 "smart lampposts" installed in Kwun Tong and the Kai Tak Development Area are undergoing tests and expected to come into operation at the end of next month.

The fixtures are part of the multi-functional smart lampposts pilot scheme that will to collect data and enhance city and traffic management.

Equipped with different sensors, data networks and related digital facilities, the lampposts can collect real-time data like weather, environment and traffic.

Most of the smart devices are installed inside the lampposts' pillars or cases to ensure they can operate under any weather condition.

The sensors, which will collect various kinds of information, include a traffic detector and panoramic camera that can gather real-time traffic data, such as vehicle types and traffic flows. Meteorological sensors collect temperature, humidity and wind speed. Air quality sensors can gather air quality data at the district level.

Lighting is the main function of the fixtures, which use light-emitting diode and LED lighting with a smart lighting management system to save energy.

Highways Department senior engineer Cheng Chung-shan said LEDs consume less energy and emit less carbon dioxide.

"[Compared with] the road light, it brings about a 30 percent reduction in energy. Matched with our smart control system, the energy saving can be further enhanced. After midnight when the illumination is not required to be so bright, we can dim it to a certain degree."

The Office of the Government Chief Information Officer's senior systems manager, Dantes Tang, said the lampposts are suitable for installing microcell stations of fifth-generation mobile communications services to provide wi-fi and future 5G services.

"To complement the development of 5G in Hong Kong, we have reserved spaces for the mobile network operators to install their microcell base stations into the smart lampposts," Tang said.

Under the scheme, the government plans to install about 400 smart lampposts in three years in four urban locations - Central and Admiralty, Causeway Bay and Wan Chai, Tsim Sha Tsui, and Kwun Tong and the Kai Tak Development Area. Some smart lampposts to be installed in Central, Admiralty, Causeway Bay and Wan Chai,are expected to come into operation by the end of the year.

Tang said the scheme's performance will be evaluated next year.
