Influence of Emergency Vehicle Preemption on Travelling Time and Traffic Safety in Urban Environments enabled by Innovative Behavioral Models and V2X Communication - Simulation and Case Study

Emergency vehicle missions underlie high risks in traffic. Having emergency vehicles only equipped with light and siren, other traffic participants will not be reached by a warning and behave inadequate. These situations pose a high risk which may be reduced by introducing novel systems for protecting both the emergency vehicles and the surrounding traffic participants. As novel systems could have a severe impact on the traffic itself, simulations are useful in order to estimate the benefit or avenues of further improvements. One system is a preemption system which is developed for a real traffic environment and evaluated regarding travelling time and traffic safety. Beside, this paper develops needed behavioral models for both emergency vehicles and individual traffic and integrates them into the traffic simulation.
