I'm interested in traffic control devices and CD4000 discrete logic. I've been playing around with this traffic light controller circuit. Current version uses two CD4017 counters, a single CD4027 JK flip-flop + some OR & NOT gates.

The basic works, but does /ohm/ have any ideas how to implement different time delays for different light phases? I've seen a lot of 4017 circuits and most/all of them are using a lot of diodes to connect 4017 outputs in parallel.
