The survey, which began on March 10, aims to assess the traffic safety situation on roads with steep terrain such as National Highways 6, 4E, 4D, and 12. After completing the survey, the delegation will compile the results, organize professional workshops and prepare an evaluation report to propose management solutions to ensure the safety of double-decker sleeper buses. Colonel Pham Quang Huy, deputy director of the Traffic Police Department, said the survey aims to assess factors affecting traffic safety on northwestern mountain roads, including transport infrastructure, traffic signage systems, vehicle flow, traffic organization, and accident black spots and areas with potential risks. Authorities will also assess transport management, including permitted vehicle types, operational routes, itineraries and service frequency, in order to propose the operating scope and conditions for double-decker sleeper buses. Nguyen Thanh Hoai, deputy director of the Vietnam Road Administration, said double-decker sleeper buses are widely chosen by passengers.
