Influence Law of Urban Rail Transit Delay Propagation under Network Operation

Network operation perplex train delay and passenger flow delay which are the two typical representations of delays. Several train diagram models were set up to analyze train delay propagation characteristics and passenger flow affect. The most prominent characteristics is network dynamic property, and main factors are utilization of carrying capacity, distribution of delay and location of delay. Therefore computer simulation is applied for a case study of Shanghai Metro’s Line 2 to find the influence law of these factors. Firstly, the simulation results help summarize several challenges of delay propagation for Urban Rail Transit (URT) Organization. Secondly, it is found that Operation Reliability is an important indicator of Urban Rail Transit Organization. The mutual effect between delay propagation and carrying capacity has been mainly reflected in actual URT Organization. Lastly, this paper provides URT with strategies to deal with these influence relation.
