Why Do Traffic Lights Take So Long In Las Vegas?

There’s nothing worse than driving in traffic while commuting to work — except sitting at a long stoplight during that commute, of course. The duration of a stoplight varies from state to state, town to town, even intersection to intersection — and some are much longer waits than others. There’s an infamous traffic light in New Jersey that is red for 57 minutes each hour, staying red for 2 minutes, 15 seconds, and going green for only 8 seconds repeatedly.

These massive intersections sometimes have multiple left, through, and right lanes. This means there are a lot of cars and large waves of pedestrians crossing wide streets in all directions. On some intersections with six lanes, it can take pedestrians 120 seconds or more to get across the walkway…
