These light controlled crosswalks are causing more harm and danger than any good. Unsuspecting newbie pedestrians are trusting and expecting Thai drivers (worst, most unobservant, apathetic and oblivious drivers on earth) to STOP. They are fooled and not looking all ways before actually crossing. Many just blow through at speed. This is chronic everywhere in Thailand. Much safer to just wait for traffic to pass and safely cross while actually observing the conditions, instead of trusting ineffective lights, sound effects and these idiot drivers.
Happens to Thais too...
