In many places in the US, pedestrian buttons don't change the lights, certainly not within 1-3 min, if it's a busy or major intersection with lots of vehicle traffic. Also, the controller behavior can change during the day/night depending on traffic volume, or maybe time of day. One time I counted it took the lights 7 minutes to change at a three-lane intersection late at night, even though there were no cars. https://news.ycombinator.com/item?id=12330251 https://news.ycombinator.com/item?id=12330251 https://news.ycombinator.com/item?id=17900576#17906527 https://news.ycombinator.com/item?id=17900576#17906527 BBC: "Does pressing the pedestrian crossing button actually do anything?" https://news.ycombinator.com/item?id=6326588 https://news.ycombinator.com/item?id=6326588
