Urban thresholds are about access and affect. They are created through intangible sensory boundaries that insinuate who gets to go where and when, and with what kinds of expressive behavior. Even though the physical space of a city may ostensibly be open to everyone moving  within it, sensory and affective thresholds enable access for some pedestrians and not for others, creating insiders and outsiders, inclusion and exclusion. Vision is a powerful tool in creating urban thresholds, in particular the vision of the city planner, who lays out prescribed uses of the urban space, and the surveillance practiced by authorities and residents to enforce those norms. But urban thresholds also rely on sonic, kinetic, haptic, and olfactory cues, which feed into affective responses. Moving beyond the emphasis on visibility as a strategy of control, we ask how the embodied process of moving through an urban space creates a sense of entitlement to, or exclusion from, the full and free use of the city? What kinds of examples of urban thresholds can we identify, historically or today, in Newark, for instance in the four streets of the Grid?
