What ND filter to get?

I am interested in shooting human motion against buildings in bright daylight. Any suggestion on how high a ND filter (not the brand itself - though I am fine with that kind of suggestions too - but more like how many stops) I should get? (I guess about 1 sec shutter speed, general f5.6 or f8 - right?)

Thanks.

I guess my question is: how many stop reduction is "most useful" to get.

This table gives you the answer. What else is missing?
Take a shot at your designated location with your target aperture and ISO 100, check shutter speed. Count the stops to get 1s (or whatever speed you wish to achieve). Check the table.

How much human motion? Also depends on ambient lighting. Bright sunny day and overcast day will have difference. Suspect 2-3 stops will do

bright sunlight, so Sunny f16 rule, exposure should be ISO 200 f11, 1/500, for motion blur effect of human traffic, you need 1/4 sec to 1 sec shutter speed depends on how close or how far of your subjects, now you can do your own math. :)
