Abstract: For the super-large scale rail transit system that has conflicts between transportation capacity and passenger volume, it is urgent to further increase transportation capacity of multiple lines in the whole network, while the transportation capacity bottleneck is mainly reflected in the restriction of equipment capacity. In order to systematically increase transportation capacity, the influences of various equipment capabilities are comprehensively considered and evaluated. Based on the demand of Shanghai rail transit network capacity increase, seven influencing equipment capability factors, their inter-correlations, and their restrictions on transportation capacity are expounded, and the evaluation methods of each equipment capability are analyzed respectively. The evaluation results summarize current Shanghai rail transit network equipment capability problems, and the improvement countermeasures are given. Finally, suggestions on the work implementation, technology improvement and the planning and design are put forward.
