  Shared situation awareness (SSA) has been garnering explosive interest in
various applications for intelligent transportation systems (ITS). In addition,
the delay-constrained nature of supporting vehicular networks makes it critical
to precisely analyze the performance of a SSA procedure. Extending the relevant
literature, this paper provides an analysis framework that evaluates the
performance of SSA in spatial and temporal aspects simultaneously.
Specifically, this paper provides a closed-form probability distribution for
the length of time taken for constitution of a SSA among a group of connected
vehicles. This paper extends the calculation to investigation of feasibility of
SSA in supporting various types of safety messages defined by the SAE J2735.
