Abstract: In order to enhance the fire emergency capability of Guangzhou metro rail transit, a mathematical model was built to study the optimal site selection of metro fire emergency rescue stations. First, a time limit model and a required and non-selected station model were established considering the actual situation of Guangzhou metro rail. Then, Lingo 18.0 was used to solve the time limit model, and then the required and non-selected station models were used to optimize. For the repeatedly covered fire emergency rescue service demand stations, select the nearest metro fire emergency rescue station as the departure station of the fire emergency rescue force of the demand station. Finally, 40 stations from 241 metro stations were selected as metro fire emergency rescue stations to achieve the coverage of rescue services for all metro stations.

Key words: metro, fire emergency rescue station, emergency response time
