ABSTRACT
This chapter diagrammed the basic legal and design standards, the rules of the road, that help choreograph spatial relations within the street as place of flows. It chapter analyzes these rule systems whose purpose is to control and score flows as traffic, which reinforce intended patterns of movement through the durable materiality of infrastructure and power of the law. It begins with a broad review of applicable national standards. But because most roadways are designed and regulated by states, one must be cognizant of local standards. The chapter focuses on the discourses of order and control as manifested through the social and material space of transportation infrastructure, of asphalt, concrete, metal, and paint, in the attempt to structure the practice and politics of mobility. It approaches the intersection not as a question of transport policy so much as the basic spatial and temporal fabric, the choreography, of everyday urban life.
