At a meeting held at the Hanoi Department of Construction on the afternoon of October 21, Colonel Trần Đình Nghĩa, Head of the Hanoi Traffic Police Department, stated that the issue of vehicles encroaching on roadways, which disrupts traffic flow, stems from high-rise buildings lacking underground parking or dedicated parking lots. Notably, Nghiêm Xuân Yêm Street transforms into a massive parking lot every night.
