In order to enhance the emergency response efficiency of fire rescue zones, a block accessibility-based method for dividing fire rescue territories was proposed. Basic data were obtained through block boundary extraction, as well as the localization of fire stations and demand points. Multi-period real-time traffic data were acquired via an online map to calculate the integrated travel time from each fire station to every block unit, which served as the basis for division. Blocks were assigned to the corresponding fire station based on the shortest accessibility time. Finally, an optimized zoning scheme and an evaluation of the overall regional accessibility were output. A case study was conducted in the HN-FR area, involving 8 fire stations and 10 067 demand points. A total of 542 block units were extracted, and analysis was performed using 618 483 data samples across 29 scenarios. Results indicate that the overall accessibility time for the HN-FR region is 435.96 s, reflecting relatively poor fire rescue accessibility. Furthermore, significant disparities are observed in the areas of the eight fire station territories, ranging from 0.37 to 12.36 km2. This variation is primarily attributed to the proximity of some fire stations to the boundary of HN-FR, resulting in minimal coverage capacity.
