Many factors contribute to it. For starters, there are too many vehicles which automatically leads to congestion on our roads.But another significant problem that worsens traffic is bad driving habits.

Coupled with the Thai aspiration to own a car and get some status, this policy has resulted in five million vehicles in a city which can only cope with less than two million cars.
