According to many experts, a group of students from the the University of Education and Technology, a member school of the University of Da Nang (UD) and the Duy Tan University have done researches that not only won high prizes in competitions but also aimed at coming up with urban architecture construction solutions, focusing on social issues of deep concern.

Reasonable traffic organisation

Desiring to reduce traffic congestion in such big cities as Ha Noi, Ho Chi Minh City and Da Nang, a group of students from the University of Education and Technology, including Pham Thanh Hung and Huynh Van Tai, joined efforts in conducting ‘Rational organisation of traffic on branches leading to traffic intersections controlled by light signals”. This research overcame 182 projects and won the second prize of Loa Thanh Award in 2022.

Pham Thanh Hung, the research team leader, said that the team spent more than 3 months planning the survey at key intersections across the city and collect data at the municipal Traffic Light Control Centre.

The main problem of the study is to calculate the appropriate turn-by-turn lights for each type of vehicle. Thereby, the team calculates vehicle traffic and designs the most reasonable traffic lights.

Traffic jam handling solutions taken by many advanced countries worldwide were also collated and applied by the group. “In order to improve the efficiency of solutions at the traffic nodes, the team applied 3D technology in simulating actual intersections at the western end of the Rong (Dragon) Bridge and Xo Viet Nghe Tinh - Nguyen Huu Tho to get calculated parameters and regulate vehicle traffic close to reality.

A special feature of these two intersections is that the lane exclusively for motorbikes is pushed forward with cars behind to help limit traffic jams. Besides, the option of turning two lanes like urban reality research in China is also taken into account so that it can be applied”, Hung informed.

Huynh Van Tai, a member of the research team, said that initially the group encountered many shortcomings when applying processing technology according to survey data. However, thanks to the guidance of the university’s lecturers from the method of selection and data processing to the application of vehicle traffic calculation, the group has accomplished most of the goals of building traffic organisation solutions at the intersections.

It is hoped that the research will limit traffic congestion at the intersections and solve the problem of conflicts between traffic branches at the entrance.

Assoc.Prof.Dr. Phan Cao Tho, the Rector of University of Education and Technology, who guided the research team, said that that the reasonable organisation of traffic on the branches leading to traffic intersections controlled by light signals is not only decisive convenience when participating in traffic but it also plays an important role in economic development. Therefore, measures to organise reasonable traffic on branches leading to intersections are very necessary.

Speaking at the Loa Thanh award ceremony, Mr. Nguyen Minh Triet, the Secretary of the Central Committee of the Youth Union, Chairman of the 2022 Loa Thanh Award Council commented: "Solution to organize traffic on branches leading to traffic intersections controled by light signal is completely feasible, contributing to the construction of theory of organisation and control of mixed vehicles with many components in urban Viet Nam".

Monitoring station using renewable energy

The project of monitoring stations to monitor water environment parameters using renewable energy sources such as water flow, wind and sun has been completed by a group of three students of the private Duy Tan University. Phan Van Truyen, the leader of the research team, said that through the survey, the team found that all monitoring stations make the only use of solar energy. However, this energy source is not enough to use at night or when it rains. Besides, the 3G and GPRS data transmission technology that monitoring stations are using consumes a lot of energy.

Meanwhile, sources from water, wind and solar energy not only help the system work well in the absence of energy sources, but they are also environmentally-friendly.

“The team takes advantage of the motion of ocean waves and wind to spin turbines combined with solar panels. This power source will produce continuously, without interruption regardless of day and night. In addition, the monitoring station also uses LoRa data transmission technology with much lower power consumption than 3G and GPRS. My team is very happy that this research won the third prize in the contest “Innovative Products Expo 2022” and the first runner-up at the Schneider Go Green 2022 contest, both of which offered a great motivation for the team to try to come up with new more practical project”, happily said Truyen.

According to Master Nguyen Pham Cong Duc, who guides the information research team, the monitoring station will provide instant data if the water environment is polluted as well as monitor the status and quality of water to provide timely solutions. Currently, the project is being perfected and it is tested at local beaches.
