Abstract: Aiming at the prominent problems including isolated ticketing systems, unavailable cross-network one-ticket travel, and mismatches between ticket revenue clearing results and actual operational contributions during the integration of suburban railway and urban rail transit networks, this paper designed an integrated ticketing, fare calculation and clearing system for suburban railway and urban rail transit. It adopted technologies such as parametric network modeling and multi-dimensional measurement and analysis, and realized functions including compatible fare calculation for multiple ticket types, multi-factor precise clearing and multi-scheme simulation evaluation. Experimental results show that the system achieves accurate fare calculation of full OD flow data under integrated networks and dynamic generation of multi-dimensional clearing ratios. Compared with traditional models, the matching degree between clearing outputs and the actual operational contributions of lines improves significantly.
