In this paper we attempt to clarify the definition of mixed reality as a more abstract concept of combining the real and virtual worlds – that is, mixed(More)
A testbed for evaluation of online distributed simulations of transportation system infrastructures is described that includes a modest portion of an urban road network in the midtown region of Atlanta, Georgia. The testbed includes sensors, servers, wireless communications, and mobile transportation simulations configured to model the testbed region. The(More)
