Vietnam's road system includes national roads administered at the central level, provincial roads managed at the provincial level, district roads managed at the district level, urban roads managed by cities and towns, and commune roads managed at the commune level. Bicycles, motor scooters and motorcycles remain the most popular forms of road transport in Vietnam's urban areas, although the number of privately owned automobiles is also on the rise, especially in the larger cities. Public buses operated by private companies are the main mode of long-distance travel for much of the population. Vietnam operates 21 major civil airports, including three international gateways: Noi Bai in Hanoi, Da Nang International Airport in Da Nang, and Tan Son Nhat in Ho Chi Minh City. Tan Son Nhat is the nation's largest airport, handling 75% of international passenger traffic. According to a state-approved plan, Vietnam will have 10 international airports by 2015.
Education in Vietnam is a state-run system of public and private education run by the Ministry of Education and Training. It is divided into five levels: preschool, primary school, secondary school, high school, and higher education. Formal education consists of twelve years of basic education. Basic education consists of five years of primary education, four years of intermediate education, and three years of secondary education.

The main education goal in Vietnam is "improving people's general knowledge, training quality human resources, and nurturing and fostering talent."
Vietnam in the northern regions has a humid subtropical climate, with humidity averaging 84% throughout the year. However, because of differences in latitude and the marked variety of topographical relief, the climate tends to vary considerably from place to place. During the winter or dry season, extending roughly from November to April, the monsoon winds usually blow from the northeast along the China coast and across the Gulf of Tonkin, picking up considerable moisture; consequently the winter season in most parts of the country is dry only by comparison with the rainy or summer season. During the southwesterly summer monsoon, occurring from May to October, the heated air of the Gobi Desert rises, far to the north, inducing moist air to flow inland from the sea and deposit heavy rainfall. The climate in the southern regions especially Ho Chi Minh City and surrounding Mekong Delta is predominantly Tropical savanna climate with high humidity and a distinct wet and dry season.
