Specifically, step S12 includes：
Determine the target frequency of second train, the arrival time of first train and second train
The difference of target frequency is the first predetermined threshold value；
Judge second train in the parking at the current station according to the target frequency of second train
Between whether be less than the 3rd predetermined threshold value；
If being less than, sending for second train is adjusted to the target frequency constantly.
If it should be noted that adjustment frequency so that frequency is earlier than to due in, arrive at a station train deceleration
Period at utmost overlapped with the Acceleration of starting period of departing trains and cause the second train in the parking at current station
Between be more than the maximum dwell time (the 3rd predetermined threshold value), then the frequency of the second train is not adjusted (as shown in Figure 3).
Below by taking swallow room line route map of train as an example, illustrate the train diagram establishment method of the embodiment of the present invention.
By taking the service chart of swallow room line as an example, in the route map of train of the uniform departing time interval of completion prepared in advance
In, from left to right (i.e. with the order of due in morning and evening), begun look for from the first bus time of departure, find upstream or downstream side
To first train to arrive at a station, if this train be from care for eight way stations dispatch a car 6:43:36 reach the up platform in Star City station,
So look over whether the descending platform in Star City station has train departure (to pay attention in previous minute or latter minute：One minute is to set
The fixed adjustable time).If not provided, so continue from left to right to search 6 by service chart:43:It is leftmost after 36
First train to arrive at a station.If so, if this is 6 from Star City station to the train of eight way stations of Gu:43:01 sends out at Star City station
Car, then postpone time of departure of train to 6:43:30 (pay attention to：Here set 6 seconds is when dispatching a car overlapping with arrival train
Between, i.e., in 6 seconds, deceleration train can accelerate train can be from the operation of static acceleration in 6 seconds from braking is started to coming to a complete stop
Speed).Continued search in the service chart of swallow room line, until the last bus off-running time.
