Vinh City: First time applying "green wave" technology to traffic light signals

On October 31, 2017, Vinh City issued Decision No. 7496/QD-UBND approving the investment in the construction of a traffic light project at the intersection of Le Nin - Le Hong Phong - Truong Thi - Vo Nguyen Hien - Nguyen Phong Sac (Hai Quan intersection) and connecting the green wave on the Le Nin - Truong Thi, Ho Tung Mau - Phan Dang Luu streets.

Accordingly, the city will install 5 traffic lights on Truong Thi Street towards Ben Thuy Bridge; Vo Nguyen Hien Street towards Lam River; Le Nin Street towards the airport; Le Hong Phong Street towards Quang Trung and Nguyen Phong Sac Street towards Provincial Road 535.

The project has a total cost of 3.3 billion VND, of which construction cost is 2.7 billion VND. Capital from the provincial budget accounts for 70% of the total investment capital, Vinh City budget accounts for 30%.

Vinh City has now completed the installation of the traffic light system and is preparing to equip the lamp posts with solar panels. It is expected to be operational before the Lunar New Year.

Notably, this is the first time Vinh City has connected "green wave" technology to traffic lights on Le Nin - Truong Thi and Ho Tung Mau - Phan Dang Luu streets.

Mr. Vo Minh Duc - Chief of Office of Provincial Traffic Safety Committee said: "Green wave" technology will synchronize traffic light signals, the control capacitors will program and calculate the distance and average travel time of traffic participants to coincide with traffic light signals. This technology helps reduce waiting time for traffic lights, reduce congestion and has been applied in many cities.

For example, when a person moves from intersection A with the green light on, the controller will calculate the time so that when that person arrives at intersection B, the green light on B will also be on, and traffic will flow smoothly.

The goal of this project is to gradually complete the traffic infrastructure, contribute to the urban beautification of Vinh City, reduce traffic jams during rush hours, especially during the upcoming Lunar New Year./.
