The Tai Tam Road (Dam Section) is part of the thoroughfare connecting Chai Wan and Stanley. Although it is only five metres wide, widening the road section is not possible as the dam is a declared monument. Hence, congestion problems occur when larger vehicles use the road section. To solve this problem, we have developed a Smart Traffic Control System by applying video analytic technology, which has been commissioned since August 2018, to collect real-time traffic information and adjust the duration of green signals.

Uniqueness and Competitive Advantages:

  • Eight sets of traffic detectors are installed within 400 metres of either side of the scenic but congestion-prone road
  • Vehicle types and dimensions can be detected and analysed for calculating the most effective green time
  • The detectors capture images from a high angle to avoid weather, light and environmental impacts and protect drivers’ privacy

Handheld High-Resolution Short-Wave Infrared Spectrometer

Spectrometers are widely used in many different aspects, such as food and environmental inspection etc. However, it is necessary to have a portable and high-resolution spectrometer for real-time on-site inspection at remote farm or factory. CUHK team invented two new technologies, which broke the traditional boundary. We develop a handheld high-resolution short-wave infrared (SWIR) spectrometer […]
