The Ministry of Transport has just issued a document requesting the Vietnam Road Administration, Vietnam Expressway, Construction Investment Management and the Project Management Boards of Ho Chi Minh , My Thuan, 2, 6, 7, 85, Thang Long to review the expressway investment phase designed with 4 lanes for motor vehicles (2 lanes on each side) to be able to operate at a speed of 90 km/h.
According to the report of the Ministry of Transport, currently, some expressways with 4 lanes for motor vehicles with intermittent emergency lanes are invested and put into operation with a maximum speed of 80 km/h.
On June 22, 2022, the Vietnam Road Administration issued and announced the Basic Standards for Expressways - Design and Traffic Organization in the Investment and Construction Phase. Accordingly, expressways with investment phases of the above scale can operate at speeds up to 90km/h.
To ensure unity and synchronization in traffic organization for the expressway with 4 motor lanes, improve investment efficiency, and promote socio -economic development, the Ministry of Transport assigned the Vietnam Road Administration to coordinate with the Vietnam Expressway Administration and the Department of Construction Investment Management to review relevant technical factors of the expressway with 4 motor lanes in operation or being prepared for investment to assess the suitability and decide to increase the operating speed to 90km/h.
The Vietnam Road Administration reports to the Ministry of Transport to direct investors of expressway projects to proactively adjust traffic organization plans or necessary technical solutions, adjust technical design documents such as adjusting signs and paint lines, to meet the need to increase operating speed when put into use.
Project Management Boards are responsible for coordinating with the Vietnam Road Administration to provide test results and assessment reports as required, and are responsible for reviewing and making recommendations for projects under their management; directing units to adjust and supplement construction items according to the opinions of the Ministry of Transport and the Vietnam Road Administration to ensure traffic safety conditions when increasing vehicle operating speed.
The Ministry of Transport also requested responsible units to implement and report results to the ministry before December 31, 2023.
Some expressway sections have completed construction and put into operation with a maximum speed of 80 km/h and a minimum speed of 60 km/h, such as Cao Bo - Mai Son, Trung Luong - My Thuan, Mai Son - National Highway 45 - Nghi Son, Nha Trang - Cam Lam and Vinh Hao - Phan Thiet.
In the question and answer session at the 6th Session of the 15th National Assembly on November 6, Minister of Transport Nguyen Van Thang said that currently, we have speed limits. The highest is 120 km/h, followed by 100 km/h, 80 km/h and the lowest is 60 km/h. These standards depend on technical factors. If the investment is complete and synchronous like the Ha Long - Mong Cai route, it can run up to 120 km/h.
Or on the same route, Phap Van - Cau Gie is 100 km/h but Cau Gie - Ninh Binh is 120 km/h. The simple reason is that just adding the roughness factor can increase the speed from 100 km/h to 120 km/h.
According to Minister Nguyen Van Thang, since the beginning of 2023, the Ministry of Transport has been reviewing and reviewing whether the expressway standards are suitable for reality. Recently, the agencies have researched and found that routes with a speed limit of 80km/h can be increased to 90km/h, but larger speed ranges must still comply with regulations and standards.
“The Ministry of Transport is adjusting highway standards and regulations. It is expected that in the first quarter of 2024, the speed limit on some highways will be changed from 80 km/h to 90 km/h,” Minister Nguyen Van Thang affirmed.
