Traffic on Thai Ha Street on Monday afternoon.
Phan Le Binh, a lecturer of the Construction Engineering Program at the Vietnam Japan University in Hanoi, said the capital's streets are often congested on weekdays, but traffic jams at the end of the year are more intense due to higher demand for good transportation and shopping.
In addition, many vehicles carrying bulky packages and people stopping to buy Tet items sold on the sidewalk also contribute to more serious congestion, he said.
