Three students from the Hong Kong Institute of Vocational Education (IVE) (Shatin) in Community Service Planning and Navigation Higher Diploma, Higher Diploma in Computer and Electronic Engineering collaborated across boundaries to design a "smart bus stop" after a field visit to the old district of Sham Shui Po. Four functions such as notifying the bus driver in advance to stop, reduce the "flying stop" situation caused by the driver's line of sight being blocked.
Their invention added a sensor to collect air data records, helping bus companies to improve and control air pollution problems, so as to improve the quality of life of residents.
The design work won the Gold Award and the Best Creative Design Award in the "Smart SMART New Life" Creative Engineering and Architectural Design Competition in July.
Apply cutting-edge technologies such as cloud IoT
Zhen Huiyu majored in community service planning and navigation, and is one of the design team members.
She said, "Our bus has a warning light for those who get off the bus, but not for those who want to get on the bus." One of the main purposes of the smart bus stop is to remind drivers that someone is about to get on the bus to avoid missing, thereby reducing the problem of flying stops.
The entire design work includes a blue indicator light, mobile app, bus stop display and buttons.

Zhen Huiyu explained in detail how to use the bus stop.
First, passengers can press the button corresponding to the bus they want to take at the bus stop, and the bus number will be displayed on the display.
When the bus driver approaches the stop, the blue light on the bus will light up to remind the driver that someone will be on the bus at the next stop.
After the passenger has successfully boarded the vehicle, the driver can press the cancel device.
In addition, if passengers have not yet reached the bus stop, they can download the mobile APP, find the corresponding bus on the APP and choose to get on the bus, and the blue indicator light will also light up.

Zhang Zian and Chen Haoran majored in computer and electronic engineering and were responsible for the technology part of the work.
He pointed out that the material cost of the work is relatively cheap, at five or six thousand yuan, and the cloud, Internet of Things and other technologies are comprehensively applied. Among them, the mobile phone relies on the low-power wide-area network technology LoRa to transmit the signal, which is effective within 30 to 45 kilometers, and the signal is uploaded to the cloud server. After the device is processed.
In addition, sensors can be installed at bus stops to collect regional air data records and transmit them to relevant departments. It can also assist bus companies to control the location and flow of stations and set up low-emission zones, thereby improving and controlling air pollution problems and protecting the health of residents.

The team gathered 60 neighbors in two stages to facilitate the visually impaired and other groups
Au Qiwen (1st left), lecturer of the Department of Early Childhood, Elderly and Social Services of IVE (Shatin), and Du Jingting (2nd left), lecturer of the Department of Engineering, said that the inter-professional cooperation among the three students is expected to be integrated into community service at the same time as students develop computer design. People-oriented concept, learn from the perspective of people; the main service targets of smart bus station include visually impaired, disabled, elderly, office workers, students, housewives and other groups.

Spend half a year making a drop zone to collect opinions
Zhen Huiyu said that from conception to actual production, the entire work took one and a half years.
In the preliminary design, the area was divided into two stages. The first stage went to Sham Shui Po and Shau Kei Wan to collect opinions from 30 neighbors.
During the interview, Zhen Huiyu discovered that the community planning was flawed. "The visually impaired and the disabled may not be able to get on the bus successfully."
For the visually impaired, if the embossed sign is too small, it may be difficult to read or take the wrong car.
The roads in Sham Shui Po are narrow, and the view of bus stops is sometimes blocked by illegal parking. Disabled people in wheelchairs are prone to miss the bus.
In the second stage, after the preliminary design of the product was completed, Zhen Huiyu asked about 30 citizens from different institutions such as the elderly center for their opinions, and it would be clearer to learn more about the words and distances that the elderly used to read on weekdays.

Zhang Zian said that the participating judges gave many suggestions, including the waterproof function of the button in rainy days and the problem of signal interference.
Now, the team is contacting the Innovation and Technology Foundation to deepen the design and improve the corresponding problems.
Zhen Huiyu pointed out that she hopes to make the design work more mature as soon as the end of this year, and get the permission of the Transport Department and other relevant departments to actually test it in a suitable area.
The Creative Engineering and Architectural Design Competition is co-organized by the URA in partnership with the Hong Kong Institute of Vocational Education (IVE) and the Hong Kong Design Institute (HKDI) under the Vocational Training Council (VTC), and has been held for 5 consecutive years.
The theme of this year's "Smart SMART New Life" is to encourage tertiary students to come up with architectural design solutions on different issues in the old district of Sham Shui Po, so as to improve the quality of life of residents in the old district.
This year’s contestants are required to take the old Sham Shui Po area as the foundation, and use intelligent technologies or information technologies such as artificial intelligence, Internet of Things, data analysis and cloud technology to submit an architectural design including sustainable forests, or to invent a smart home device , building services or public facilities to promote smart living and enhance the quality of life of residents in old districts.
