With a spread of mobile devices, the growing trend of
integrating wireless communications technologies into transportation systems is
advanced. In particular, vehicular ad hoc networks (VANETs) enable vehicles to
share traffic information that they have through intervehicle
communications. This research focused on the design of an integrated
transportation and communication simulation framework to build an environment
that is more realistic than previous studies developed for studying VANETs.
Developing a VANET-based information model, this research designed an
integrated transportation and communication simulation framework in which these
independent simulation tools not supporting High Level Architecture (HLA) were
tightly coupled and finely synchronized. As a case study, a VANET-based traffic
information system was demonstrated based on a real road network and real
traffic data. The experiment results showed that the simulation framework was
well integrated. The simulation framework designed in this study is expected to
contribute to developing the environment to experiment a wide range of VANET
applications.
