Evaluating the Impacts of Connected Vehicle Technology on Evacuation Delay

No-notice evacuations of metropolitan areas can place significant demands on transportation infrastructure. Connected Vehicle (CV) technology, with real-time vehicle to vehicle and vehicle to infrastructure communications, can help prepare emergency managers develop efficient and cost-effective traffic management plans for these no-notice evacuations. The objectives of this research were to evaluate the impacts of CVs on the no-notice evacuation of a downtown metropolitan area. The microsimulation software VISSIM was used to model the roadway network and the evacuation traffic. The model was built, calibrated and validated for studying the performance of traffic during the evacuation. The researchers evaluated system performance with different CV penetration rates (from 0 to 30 percent CVs); and measured average speed, average and total delays. The findings suggest significant reductions in total delays when CVs reached a penetration rate of 30 percent, albeit increases in delays during the beginning of the evacuation. Additionally, the benefits could be greater for evacuations that last longer and with higher proportions of CVs in the vehicle stream.
