Observational data about bike riders interacting in traffic falls under public behavior because the activities of these individuals occur in a public setting where they can be seen by anyone. When people engage in actions such as riding bikes on streets or in other shared environments, their behavior is accessible and visible to the public, which aligns with the definition of public behavior.

In this context, the data collected does not require special permissions or confidentiality considerations, as the interactions happen in open spaces where individuals do not have a reasonable expectation of privacy. This makes the information gathered relevant for analysis without ethical concerns typically associated with more private or confidential behaviors. Understanding this distinction is crucial for determining the appropriate regulations and ethical standards applicable to research involving human subjects.
