HCM CITY— During his years at International University under the Việt Nam National University-Hồ Chí Minh City, Phan Ngọc Hưng graduated with top honours and was the valedictorian in both his undergraduate and postgraduate degree programmes.

The 26-year-old, who has won a full scholarship to pursue a doctoral degree at Norway’s Tromoso University – The Arctic University, has developed, along with other teammates, a pilot smart traffic-surveillance system for the city.

“Luckily, I was chosen to take part in the city’s pilot project on the development of a smart traffic-surveillance system which has been installed on Võ Văn Kiệt Avenue. I learned how to apply academic knowledge to solve real problems,” Hưng said.

Hưng was in charge of developing a module for detecting and classifying moving vehicles in crowded scenes. The surveillance system extracts data that assists users in regulating and managing traffic conditions at monitoring sites through static surveillance cameras.

The system consists of three main parts: an image signal processing centre, simulation centre and traffic operating centre.

The centres provide support for traffic management systems in urban areas where the roads are burdened by steadily increasing traffic flows, causing congestion and delays and contributing to economic and environmental costs.

The main goal is to gain an understanding of traffic situations by extracting data on speed, vehicle type, density and other factors through analysis of videos from the cameras.

However, because this type of system has mostly been carried out in developed countries where cars are the main means of transport, they are not particularly suited to Việt Nam, where motorbikes dominate.

“These solutions in developed countries also require modern equipment, large costs and big data,” Hưng said. “They are unsuitable for complicated transport infrastructure situations in developing countries like Việt Nam. Through our project, I learned about other technologies that could replace these with available sources in Việt Nam.”

His research team has been developing a way to handle recognition based on the movement of vehicles under crowded conditions. The solutions of the research team will be tested experimentally on actual data samples collected and extracted directly from the surveillance cameras.

The research will play an important role in improving the system installed on Võ Văn Kiệt Avenue, and, at the same time, is a premise for further studies on expansion of the system.

Functions that can be exploited from future research include the automation of peak-hour signals and warnings about potential congestion. This will help reduce traffic pressure at intersections during peak hours.

The system will also provide the most accurate statistics and information about traffic so that authorities can upgrade transport infrastructure.

Last year, Hưng and his teammates won second prize at the AI- Challenge Contest held by the city People’s Committee and Department of Science and Technology.

The contest’s theme was artificial intelligence and smart traffic. As part of the contest, teams counted the number of vehicles of all kinds moving in different directions in videos recorded from traffic cameras.

The city will use the contest’s results to design solutions to reduce traffic congestion.

When he was a student at the postgraduate programme at the International University, Hưng became interested in computer vision, which has emerged as a critical research area with a great number of successful applications.

“Video-based traffic surveillance systems are remarkable exemplars in extracting necessary information about types, speed and other data from cameras for traffic monitoring in many metro cities. In these systems, vehicle detection plays a pivotal role in localising and classifying vehicles, which are captured within the field of view of a camera,” he added.

He is currently studying how to perform visual perception tasks such as object recognition and scene categorization at extremely high levels of speed and efficiency. These tasks could assist security observations as well as the detection of cancerous cells that would improve cancer treatments.

Hưng will continue this kind of research at the Tromoso University – The Arctic University of Norway.

“After finishing my doctoral programme in Norway, I will return to Việt Nam to contribute to the country’s development, especially in the IT field. The country has many problems and there are opportunities for IT engineers to study and develop their own solutions,” Hưng said.

“This field has been my passion for years. I saw the huge potential of the IT sector when I was in the 12th grade. Students at universities should try to identify what they want to do and their future orientation and make plans for implementation. They should also have self-discipline to ensure that they have enough time for studying and researching.” VNS

In addition to admiring spring flowers, visitors can explore a series of booths featuring traditional activities like calligraphy, toy figurines ( to he ), Van Phuc silk, Dong Ho painting, Bat Trang pottery making, or the Chuong conical hat village.

There are also folk games imbued with the cultural characteristics of the Northern Delta region like throwing cotton balls, catching a duck while blindfolded, blindfolded drumming, Mandarin square capturing, throwing darts at balloons, water puppetry, and Quan ho singing.

Quan Ho singing is one of the many activities to celebrate the Lunar New Year

Other interesting activities for visitors include the booth to write New Year wishes and hang them on trees. Many visitors come to pick buds and send New Year wishes.

The spring flower street will bring some deeply missed hometown colours to Hanoians

Ngoc Bich (Hanoi), a visitor to the event, said that, “The flower street evokes the ancient Tet atmosphere so visitors can learn about the cultures of many regions. I took my two children to the flower street and they were very happy to be immersed in traditional culture.”

Converging cultural spaces and beautiful flowers, Home Hanoi Xuan 2021 recreates the image of a delicate and rich Hanoi through cultural and artistic activities, connecting the past heritage to the present, introducing the old Lunar New Year style into the flow of modern life.

The flower street aims to contribute to preserving cultural heritage, nurturing the spirit of loving nature, protecting the environment, as well as creating cultural and spiritual values that are meaningful to the community.

In the past few days, the flower street ensured the safety of visitors by fully observing epidemic prevention regulations. The small landscape spaces are beautifully designed and airy. The organisers installed cameras to measure temperature while reminding visitors to keep their distance.

The organisers placed top priority on the health and safety of visitors

The organiser of the event said that Home Hanoi Xuan 2021 was organised for the first time in Splendora Urban Area in Hanoi. The flower street is expected to be a new spring destination for Hanoian people. Taking inspiration from the beautiful countryside with beautiful flowers and lush lawn, the street brings a peaceful and warm space for visitors to experience the traditional Lunar New Year in Hanoi.

Splendora urban area organised the flower street Home Hanoi Xuan until February 21

To allow more people and tourists to visit, the flower street Home Hanoi Xuan 2021 will welcome visitors until February 21 instead of closing on Febrary 16 as planned. The organisers will continue to ensure the highest security and safety for tourists.
