Pedestrian rules should imitate motor vehicle rules.

For the sake of consistency and to make life easier, I think the best way to handle pedestrian traffic is to follow motor vehicle rules. Some examples:

*Walk on the right side of the lane. This seems to be the most obvious one but is it as obvious to British, Japanese, Hong Kong, etc. tourists? Either way you should respect the law of the country you are in. :P
*Pass to the left.
   *Slow cars move to the right.
*Changing lanes or moving to your left/right. Look over your shoulder before changing "lanes."
*Do not brake or turn suddenly.
