One of the things that struck me immediately were the traffic signals in Danang and Saigon especially. I believe it is the same in all the major cities.
Whereas, the locals do not seem to have all the elements of the technology we know and enjoy in the USA, they seem way ahead of us regarding traffic signals. Typically situated on top of every traffic signal throughout these cities is a very noticeable timer. Not only does it tell you the seconds before the green light or walk signal changes, but each of the 3 colors are on continuous display with a countdown! Whether red, green or yellow the timers are ever changing to let everyone know how many seconds are left on that particular color.
I would have to think the additional cost must be minimal by comparison, but the value in safety and stress alleviation ought to more than compensate! Why isn't every signal in the USA so equipped!
