The invention relates to the technical field of urban rail train operation optimization, in particular to an urban rail transit city area line operation scheme optimization method, which comprises the following steps of: counting passenger flow data of each station in a line of an urban rail transit city area line and the stations, and obtaining a passenger flow index according to the stations and the passenger flow data of the stations, determining a station set according to the passenger flow index; randomly combining the stations in the station set to generate a driving scheme of the large cross-road express vehicle; generating a large intersection fast and slow train driving party by combining the driving scheme of the large intersection slow train in the line of the city area line, and generating a large and small intersection fast and slow train driving scheme by combining the running interval of the small intersection train; constructing an initial solution of the departure frequency; obtaining an optimal train operation scheme by using the optimal objective function value according to a simulated annealing algorithm; according to the optimal train operation scheme, the arrival time and departure time of the train at the station are calculated, and a train timetable is compiled. The efficiency of the city line train operation scheme is improved.
