Abstract

Recent results concerning the development and exploitation of wireless vehicle-to-vehicle and vehicle-to-infrastructure communications in future generation intelligent transportation systems are discussed, as well as simulation techniques and tools used to effectively model such systems. Specifically, new algorithms to disseminate information in vehicle-to-vehicle networks have been developed, and their performance evaluated using simulation modeling of traffic along the I-75 corridor in the Atlanta metropolitan area. Work to validate the simulations models is summarized. Field experiments with wireless communication along I-75 are described, as well as extensions of these results to investigate communication architectures for vehicular networks. Results concerning multi-resolution simulation of urban transportation networks involving the use of aggregated data from regional planning models in microscopic traffic simulations are summarized.
