eishis, yes, my (non-professional) suggestion would be to NOT punish them unless they literally run in front of a zooming truck. Even then, you can simply stop them from running, ask the truck to stop, or take them to play to a safer place to begin with.
An old Jewish book, whose author I can’t remember, lists multiple suggestions how to deal with anger. Among them, for parents – use positive attitude to deal with problem: instead of punishing for bad behavior, reward them for good behavior, or just for lack of bad one. Create competition between kids to encourage learning.
Try this for a month, if you are afraid that long-term lack of punishment will damage them. Write down how many times you give a reward or punishment daily to remind yourself to be increasing rewards and decreasing punishments, as it is very easy to go to a default behavior.
