When talking about crosswalks, we generally say they are lit (lighted if you prefer) or unlit when they have a traffic signal on them in America. However, traffic signal seems to me like a general term that may be applied to any sort of signal on the road. The flashing amber lights on some school speed limits, construction warnings, road closings, stoplights, etc. are all traffic signals.
Is there a specific term for the type of traffic signal used at crosswalks? For example,
I was going to cross the street but the /blank/ turned red, warning me not to cross.
Many people, especially those in big cities, ignore /blank/ and cross the road when they want to.
Are there terms for the other types of signals I listed?
