PERIOD OPERATING METHOD: A NEW METHOD OF TRANSPORT ORGANIZATION IN CARRYING CAPACITY-RESTRICTED DISTRICT FOR RAILWAY SPEED-RAISING LINES

摘要

Period Operating Method {POM), one way of train untwining in overcapacity section for speed-raising lines, is proposed. The basic principles of the period operating and the calculation method of carrying capacity utilization rate are enumerated. After that the general of period operating method is designed. The example analyzed indicates that under given number of trains, the utilization rate of carrying capacity goes down with the reduction of operating periods for freight trains and increase of the number of same type tracking passenger trains, which effectively alleviates the intense situation of the carrying capacity. Compared with group tracking method, this method has the advantages of higher travelling speed of passenger and freight trains, less interference and less arrival and departure tracks.
