According to the analysis of historical data of traffic ， we can known that it is significant to excavate the driving time and the regulars of the interval traveling time distribution and stop distribution . the meaning of it is to studying City Rail Transit and tracking the buffer time of the train . Only then can propose the train’s time sequence diagrams that based on the optimization of buffer time ， without changing the hardware facilities to save energy consumption of the train. The paper firstly reviews the train collision or collision accidents occurred in recent years and describes it is important to improve the reliability of train operation by optimizing the train buffer time. And then analyzes some achievements of the train operation time ， energy saving and the part of buffer time at home and abroad . we have analyzed the train station interval traveling time ， residence time， interval time and the difference of the actual traveling time of the plan ， basing on historical traffic data as the basis of city rail transit . we have found that the time of the train stop in the station obey the normal distribution and calculated the key parameters of the probability density function and distribution function . Finally we studied the distribution of the time of the center after section of a train . We have studied the calculation method of train interval traveling time ， based on the definition of the reliability of the actual train travel time . we got the optimization of formula through Bias decision theory . In order to make the train operation plan time on the reliability to meet the expectation ， we have put forward the best method to adjust train operation plan and buffer time . and calculated the reliability of traveling time of the train in plan ，by the subway line 1 in NanJing that is from MaiGaoQiao to HongShan Zoo . According to the formula we have calculated the tracking train running schedule after adjusted . (责任编辑：qin) |
