This study conducted an operational evaluation of an emergency vehicle preemption system that can be operated as a wide-area unit beyond the boundaries of local governments. Analyzed the speed reduction rate of emergency vehicle dispatch data and traffic speed data to analyze the speed reduction rate of emergency vehicles operating in a wide area and region. In Goyang City, local dispatches were reduced by 50.8% and regional dispatches by 55.8%, while in Paju City, local dispatches were reduced by 55.1% and regional dispatches by 62.5%. The wide-area emergency vehicle preemption system proved to be effective when emergency vehicles were dispatched outside of local boundaries, such as confirming that there were many dispatches from Paju-si to Goyang-si when there were no large hospitals nearby. This study aims to help spread the wide-area emergency vehicle preemption system. Translated with DeepL.com (free version)

Emergency Vehicle Preemption(EVP) is an operation method which helps to improve response condition of Emergency Vehicle(EV) and it has not yet been introduced in Korea. In order to implement the system, it requires step-by-step plan and selecting a priority area for trial operation. Since a municipal government such as Seoul is too large so it is limited in time and cost to analyze the whole area. Therefore, quantitative and effective selection method for priority area is critical. The aim of this study is to propose a selection method of implementation area for EVP system using the dispatch data analysis. This study also determined the priority area for EVP implementation by analyzing the dispatch data in Seoul and conducted a simulation to evaluate the effects of implementing EVP.
