Abstract

In recent years, frequent fires and explosions have occurred at electric vehicle (EV) charging stations. Previous studies primarily focused on enhancing the resistance of charging facilities and batteries to such incidents. However, research on improving the spatial accessibility of external fire services for these stations remains limited. Notably, the accessibility of fire services varies significantly under different traffic conditions. To address this gap, this study built a dynamic evaluation method for assessing the spatial accessibility of fire services, incorporating real-time traffic data. This study identified 50 fire stations as fire service supply points and 856 charging stations as demand points in Changsha, China. By leveraging the web map's application programming interface (API) to extract traffic information, real-time travel time for fire services were calculated. Over seven consecutive days, 197 estimation scenarios and obtained 168,632 valid samples were established. The results reveal that the effective coverage rate of fire services for charging stations in Changsha is 15.88 %, indicating a need for improvement in spatial accessibility. The findings provide implications for the optimal allocation and scientific deployment of fire rescue resources.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
