There are three ways traffic signals work. A) Timer mode, B) Loop sensor (under the asphalt) mode, C) Camera detection. With intersections I'm familiar with. I can with 95% accuracy tell when a signal is going to turn red and when it will turn green. There are sometimes variations, but with practice, you can figure it out.
Timer controlled: Usually signals will offer a green light to the major artery for 30 to 60 seconds depending on how they programmed it, while offering a green light to the intersecting or minor artery for 10 seconds. If I come across a low-volume side street getting more than 10 seconds, I notify the DOT or municipality and they fix it. Once you figure it out, you can time yourself so that you don't have to come to a dead stop. Brake wear is greater bringing a 3000 lb. vehicle to a DEAD stop, rather than a slow roll. So by the time I get to the light, it turns green.
Loop sensor mode and Camera detection: Both operate by detecting the presence and absence of vehicles approaching on both roadways. The main artery will get priority so you don't have to race up to a red light and jam on your brakes on the major artery. After all or most of the minor artery traffic has passed through, the major artery will get the green. Now if you're on the side street or minor artery, you do need to pull all the way up so the sensors detect your presence IF you're the FIRST approaching. But if somebody ahead of you has triggered the system, you do NOT have to race up to the light. Just back off the gas slightly, tap your brakes if necessary and by the time you get up to the car in front of you, the light will turn green. With practice you'll figure this all out. So who needs START/STOP?
Camera detection is better at detecting low-mass vehicles such motorcycles and maybe some very small cars. Many signals are programmed so if the major artery detects a huge absence, it will default to red and offer a green light to the side street/minor artery even if there are no cars on the side street!
What does this all mean? I've gotten 100K to 150K on a set of brakes. Furthermore, I don't floor it at green and have to get up to speed in 500 feet. I take a half a mile. That's why if the mfr. says I should get 25 MPG on average, I get 31.
