This study belongs to the ethnomethodological tradition of identifying the everyday practices accounting for the oiled machinery of social organization and applies this approach to understanding direction light usage. We observe a set of episodes videorecorded in North-East Italy in the urban traffic. We first unpack the meaning of direction light usage from a pragmatic perspective and then test our interpretation against the cases in our collection that seem to deviate from it. We argue that direction lights’ usage works as (...) an announcement to some road users and a request to a subset of them; in both cases, direction lights convey contextualized (indexical) coordinates about the vehicle’s prospective trajectory. We then explain the cases in which signaling is omitted and draw some implications for traffic coordination and safety. (shrink)

We discuss the important, but greatly under-researched, topic of the social aspects of human wayfinding during navigation. Wayfinding represents the planning and decision-making component of navigation and is arguably among the most common, real-world domains of both individual and group-level decision making. We highlight the myriad ways that wayfinding by people is not a solitary psychological process but is influenced by the actions of other people, even by their mere presence. We also present a novel and comprehensive framework for classifying (...) wayfinding in complex environments that incorporates the influence of other people. This classification builds upon the premises of previous wayfinding taxonomies and is further structured into four parts based upon (1) the nature of the interaction between the actors and (2) the time frame in which the interaction takes place. We highlight gaps in our current understanding of social wayfinding and outline future research opportunities. (shrink)
