While microscopic traffic simulation models are extensively being used to evaluate traffic operations and traffic management alternatives, existing models are limited in their ability to evaluate many emerging Intelligent Transportation System applications. A particular limitation is with the simulation of wireless communications between vehicles, through proposed Dedicated Short Range Communication (DSRC) or other wireless standards. While many commercial simulation models allow information to be exchanged between vehicles or between vehicles and roadside equipment, data transmission is often assumed to occur instantaneously. In reality, communication delays are function of the load of the communication network. To address this problem, the current research seeks the development of a simulation model merging microscopic traffic simulation processes with realistic wireless communication simulation is currently being developed.
