Be careful, if you drop the class for traffic_signals it brokes long distance routing, because (at least in South America) a lot of primarys and trunks have traffic_signals.
I have been using the a map with a style that applies a -1 penalty for road_speed in case of traffic signals, and it works well in cities and in long distance routing, and it improves the estimated times.
What I meant is compute using a richer routing algorithm how long traversal will take compute what length to have a reduced class, or what length/reduction combos, to match the richer alogrithm make sure to do this in both directions demote for some class/distance, or perhaps the whole length for short segements between adjoining traffic_signals essentially construct a network with road_class set so that routing on that network as garmin does, produces the same outcome as using a signals-aware routing algorithm which I realize is a tall order
