Synergia Evaluation of Multi-type Rail Transit Operation Oriented to the Four-Railway-Network Integration

The four-railway-network integration is the policy guidance of multi-type rail transit for intensive resource usage, transportation efficiency enhancement, and regional society and economy development. The synergia improvement concerning multi-type rail transit is an important rising of the service level of regional rail transit system and guidance for urbanization progress. Based on the summary of the current status and policy directions of the synergetic development, the concept and key indicators evaluating the degree of synergia are introduced. Four main synergetic patterns are distinguished referring to the typical cases, including independent operation, passenger service integration, cross-line operation, and regional coordination. Detailed patterns and evaluation indicators with respect to the passenger service integration and cross-line operation are further put forward respectively according to the improvement of passenger service and the difficulty of connection implementation. The proposed theoretical methods and indicators provide the firm support and active reference for the synergetic development of multi-type rail transit systems.
