So about signal actuation: is there any kind of system that lets multiple signals coordinate their greens to keep traffic moving, while allowing cross traffic to still be detected and get their respective greens? I am thinking of one particular stretch of road near my apartment that, no matter what time of day you drive it, you'll hit 80% of the red lights, every time. I'm wondering if it's just because the signals are being tripped by cross traffic and cycling constantly or if there is something more that can be done to improve flow on this main road. So more open-ended: what to engineers do about busy roads with multiple signals to keep traffic moving? Pre-timed all the way or only actuated or some combination of the two?
