Pattaya has bad traffic problems now, but if the City Fathers don't do some planning and construction, traffic will be impossible in a few years.
As an example, I am providing a view of northern Thappraya Road. As you can see, some streets don't connect, often separated by vacant lots.
Some of the streets on the map don't exist, or are dirt roads.
Or existing streets are so narrow that only one car can pass through. Meanwhile, vacant lots exist that could be used to make sufficiently wide passageways - if the City Fathers act soon.
In a few years, this area will be full of tall condo buildings and it will be too late to deal with the traffic.
I am using this area as an example, but it's not unique.
