Smart and Green
Mass Transit System
The Chief Executive announced the implementation of the Smart and Green Mass Transit System (SGMTS) in Hung Shui Kiu/Ha Tsuen New Development Area in the 2023 Policy Address and further expressed the devotion of the Government to taking forward the project in the 2024 Policy Address.
The Smart and Green Mass Transit System (SGMTS) in Hung Shui Kiu/Ha Tsuen and Yuen Long South New Development Areas is about 16 kilometres in length, most of which are dedicated roads. At the major and busy road junctions, grade separation arrangements will be adopted to segregate the SGMTS from the other road-based traffic. Coupled with the Real-time Adaptive Traffic Signal System to be implemented in the area, overall smooth traffic flow can be achieved. The SGMTS will adopt a green road-based mode without the need for physical rail tracks. Plying through the Hung Shui Kiu/Ha Tsuen and Yuen Long South New Development Areas, the System will serve some 300 000 residents and a working population of about 160 000 in the areas. The SGMTS will connect to Hung Shui Kiu and Tin Shui Wai Stations of the Tuen Ma Line, Chung Fu and Nai Wai Stops of the Light Rail, and the future Hong Kong-Shenzhen Western Rail Link (Hung Shui Kiu-Qianhai), as well as the existing and to-be-built transport interchange hubs in the Hung Shui Kiu/Ha Tsuen and Yuen Long South New Development Areas, providing the public with convenient feeder services to travel to various districts of Hong Kong.

Features

Introducing Green and Flexible Design ◦ Aligning with the Planning of NDA ◦ Optimising Project Cost-effectiveness
- In the planning of the Hung Shui Kiu/Ha Tsuen New Development Area (HSK/HT NDA), a Green Transit Corridor comprising a mass transit system, footpath, and cycle tracks has been planned to promote green transport and low-carbon commuting.
- The system will adopt a green road-based mode, requiring no physical tracks and overhead electrical cable which flexibly adjusting its routing and service frequencies. It can also minimise environmental impact while saving construction time and costs.
- Adoption of innovative paving materials is considered for the road surface to enhance passenger riding experience and reduce long-term road maintenance costs.
Mainly Dedicated Roads ◦ Smart Traffic Management at Shared Junctions ◦ Enhancing Convenience and Safety
- Most of the system operates on dedicated roads, with grade separation from other road-based traffic at major and busy road junctions (such as provision of elevated section).

AT MAJOR AND BUSY
JUNCTIONS
- Through design optimisation and road capacity assessments, the number of shared road junctions has been minimised. Coupled with the advanced Real-time Adaptive Traffic Signal System (RTATSS) to enable dynamic allocation of signal time, a smoother overall traffic flow can be achieved.
- Future operator will be encouraged to use vehicle-to-everything (V2X) technology for early warnings of potential risks, thereby improving road safety.

User-friendly Low-floor Design ◦ Convenient Boarding and Alighting ◦ Pleasant Covered Waiting Area
- Featuring user-friendly low-floor design and off-board fare collection system at station.
- Multiple doors at SGMTS vehicles allowing faster and more convenient boarding and alighting.
- Equipped with covered waiting areas to provide a pleasant waiting environment.
Benefits
The system will provide convenient feeder services for the Hung Shui Kiu/Ha Tsuen New Development Area (HSK/HT NDA), connecting to the nearby railway network and the transport interchange hubs within the NDA. It plays a key role in the public transport services of Hung Shui Kiu/Ha Tsuen New Development Area, complementing long-distance public transport services to other regions.
