Quantitative Evaluation of Emergency Resource Allocation in Wuhan City
Objective To quantitatively calculate the allocation of emergency resources in the main urban areas of Wuhan in 2019 and 2022,and to evaluate the effectiveness of emergency resource allocation.Methods Real-time road network traffic data was collected using big data techniques.Indicators such as traffic accessibility and emergency task volume were used to calculate the allocation of emergency resources.Statistical methods and map visualization were employed to evaluate the effectiveness of emergency resource allocation.Results In Wuhan's central urban area within the Third Ring Road,the emergency response time was generally within 10 minutes.However,many communities were on the outskirts of the main urban area where the response time exceeded 15 minutes.Stations with a high volume of emergency tasks were concentrated in the core old urban areas along both sides of the Yangtze River and Han River,as well as at Baiyushan Station in Hongshan District,which has the largest service coverage area.Conclusion In 2022,the accessibility of emergency resources in the central urban area within Wuhan's Third Ring Road showed a significant improvement compared to 2019.However,there was a trend of decreased accessibility in the outskirts of the main urban area,where the population density is lower.The locations of newly established emergency stations must comprehensively consider accessibility and task volume.
