OK, so i think the HAWK signal being off all the time unless the button is pushed is odd for a signal, and confusing to drivers who haven't seen it before. they use a similar system to the HAWK on Tinker AFB as a security barrier warning light, only it isn't off at all, it has a flashing light. so, I've taken inspiration and made what i think is a good change. i will compare the barrier signal to both the original HAWK, and the modified HAWK signal cycles.

barrier signal:

Flash yellow (2 sec on, 2 sec off): barrier inactive, no stopping
Flash yellow (1 sec on, 1 sec off): barrier activating, use caution
Solid yellow: barrier activating, slow and stop
Solid red:barrier up, do not proceed

modified HAWK:

Flash yellow: (2 sec on, 2 sec off) crosswalk clear, no stopping
Flash yellow: (1 sec on, 1 sec off) pedestrians will cross, caution
Solid yellow: pedestrians will cross, slow and stop
Solid red: pedestrians crossing, do not proceed
Flash red: pedestrians may be crossing, stop, then if clear, proceed

original HAWK:

no signal: crosswalk clear, no stopping
flashing yellow: pedestrians will cross, caution
solid yellow: pedestrians will cross, slow and stop
solid red: pedestrians crossing, do not proceed
flashing red: pedestrians may be crossing, stop, then if clear, proceed

Here is a GIF of what a modified HAWK would look like:

Original.

A flashing yellow light is a flashing yellow light, no matter the blink rate.  I actually prefer HAWK to standard signals, because people grow accustomed to ignore lights that are always green, so they sometimes don't notice them when they actually turn yellow/red.  I've seen this happen near my house.

They could have kept it simple and gone for a modified version of the pelican crossing from Commonwealth countries. Just replace the flashing yellow 'yield' phase with a flashing red 'stop and yield' phase.

This would avoid contradicting two rules that normally apply to signals, 1) that you should treat a dark signal as a stop sign, and 2) that alternating red signals mean stop and stay stopped.

Your concept avoids one of these contradictions, but not the other.

And this isn't confusing? 

You have 4 different light phases when pedestrians could be crossing.

Alternating red means stop and proceed when clear in any instance, IIRC, including railroad crossings.
