Third, some of your comparison logic is a little flaky.
Think about it some, then if you can't solve it, look at the attached LogixPro program. I am sure that many pedestrains would curse your soul if such a scheme was actually used! You need to come up with a way to save a button-push for use later in the cycle. Your method so far for the Walk depends upon a pedestrian pushing the button when the Timer T4:0 is at a certain stage (E/W Amber On, or N/S Amber Not On). Second, your walk light logic needs to be designed so that a pedestrian can walk up AT ANY TIME and push the Walk button.
Delete either rung 8 or 9 for the O:2/3 E/W Walk Light. First off, you should not normally have two rungs with the same digital output (redundant outputs).
