Expressive Type

I would really like to explore the effects to typography in public spaces. Is there a way for the type to somehow affect the behaviour in a particular environment? Can typography dictate behaviour? Can it be the dominant force that suggests what public behaviour should be in a particular environment, can it be influential enough to stop people in their tracks and make them adjust their behaviour to meet the requirements of what the type in a particular space suggests? Would people break out of their roles to subject themselves to the design of a typeface?

By taking influences from environmental design and how that discipline uses space, and combining it with graphic principles I feel there can be a way to make typography the dominating factor that controls behaviour.
