Reply to "Semaphore and 555 Timer Circuit"

I have a traffic signal circuit using a 555 timer and a 4017 counter from a couple years ago. I got it off the internet, but had to modify it to get it to work properly. Not sure my schematic is the working model (don't remember if I updated it or not?). Might be something to play with anyway.

I have since gotten an Arduino which made the traffic lights much easier. That might also make your project easier? The traffic signal circuit I had was continuous (repetitive cycles), but maybe someone here would be able to make it a one shot device with minor modifications?
