Thread: Highway Traffic Lights UX With Data

I think you're confusing "Traffic Light Camera" with "Traffic Lights" This thread is about having alert at intersections with Traffic Lights (regardless of camera or not) Not as useful as "Stop Sign" alerts (which is part of map) and help a lot when driving at night. In unfamiliar territories, I guess a warning that traffic light is ahead could be useful, especially if you're driving drunk

Update: Data seems to be similar to OSM via query highway=traffic_signals, which is horribly incomplete in my area The data in post #1 is not just for USA, it included Canada (I only sampled a few) It also have a lot of duplicates*. Here are the break down by states; which is better since no need to carry the entire huge dataset (over 220,000) if you're only going to be driving locally**
