Abstract

The invention provides a time table considering large and small intersections and a vehicle bottom application plan making method, and the method comprises the steps: drawing up a departure interval difference target function and a vehicle bottom warehouse-in and warehouse-out frequency target function according to the information of the time table for large and small intersections; constructing constraint conditions, wherein the constraint conditions comprise departure interval constraint conditions, train number continuing constraint conditions and intersection constraint conditions; based on the departure interval difference objective function and the vehicle bottom use objective function, drawing up a collaborative optimization model function; and solving the departure interval difference objective function and the vehicle bottom warehouse-in and warehouse-out frequency objective function based on constraint conditions, and further solving the collaborative optimization model function Z to obtain time table and vehicle bottom application plan scheme data. According to the method, the influence of large and small intersection plans on the compiling of the timetable and the underbody application plan is comprehensively considered, and an integrated compiling method is provided, so that the problem of repeated modification caused by compiling the timetable and the underbody application plan as two independent processes in the traditional compiling process is avoided.

Description

technical field

[0001] The invention relates to the technical field of train intelligent operation plan preparation, in particular to a method for preparing a timetable and a train operation plan considering large and small crossing roads. Background technique

[0002] Urban rail transit, as a safe, fast, environmentally friendly and efficient mode of urban transportation, has become the choice of more and more citizens. In recent years, the process of urbanization has been accelerating, the scope of urban circles has been expanding, urban rail transit lines have been extended, super-long lines have been opened and operated, and the space covered by lines has continued to expand. However, due to the unbalanced division of urban functional areas in the travel of residents, the demand for urban rail transit passenger flow varies in time and space. Urban rail operators often use large and small traffic lines to deal with the differences in passenger flow demand, and reduce ope...
