Technical Study on Seat Occupancy and Seat Belt Fastening Detection for Green Minibus

The Transport Department (TD) has engaged a technical specialist to conduct a technical study on seat occupancy and seat belt fastening detection for Green Minibus (GMB), in order to explore the feasibility of different technical solutions through a Proof-of-concept (POC) on-site trial, with a view to enhancing passengers' awareness of wearing seat belt. Details of the technical solutions can be referred to the leaflet.

POC on-site trial

The POC on-site trial has been conducted from Q3 of 2020 on eight selected GMB routes (one GMB from each route) in phases for testing and reviewing the effectiveness of different technical solutions of seat occupancy and seat belt fastening detection, as well as measures to remind passengers to wear seat belt.

List of the GMB routes involved in the POC on-site trial can be referred to the following table.

GMB Route Origin - Destination 
New Territories No. 20C Tai Po Market Station <-> Tai Mei Tuk
New Territories No. 403 Shek Lei (Lei Pui Street) > Sha Tin Wai (Circular route)
New Territories No. 36 Yuen Long (Fook Hong Street) <-> Tai Sang Wai Rural Office
Hong Kong Island No. 56 Mid-Levels (Robinson Road) <-> North Point (Marble Road)
Hong Kong Island No. 58 Aberdeen (Wu Nam Street) <-> Kennedy Town Station
Kowloon No. 27M Lok Man Sun Chuen (Maidstone Road) <-> Mong Kok Station
Hong Kong Island No. 51 Tin Wan Estate > Aberdeen (Circular route)
Hong Kong Island No. 54M Kennedy Town Station <-> Queen Mary Hospital

Trial Result and Follow-up Action

The technical study was completed in September 2021. The result showed that the tested solutions were technically feasible under normal circumstances and could detect the seat occupancy and seat belt fastening status accurately in general.

We and the technical specialist have summarised feasible technical solutions based on the data collected and opinions from drivers and passengers received during the POC on-site trial and consultations with the Public Light Bus (PLB) trades and relevant vehicle suppliers/manufacturers. With effect from 1 September 2023, all newly registered Public Light Bus are required to be installed with a Seat Belt Fastening Detection and Alert System pursuant to an additional licensing condition for PLB imposed by the Commissioner for Transport with the power under regulation 21(10) of the Road Traffic (Registration and Licensing of Vehicles) Regulations (Cap. 374E).
