Optimization methodology of bus network along metro corridors based on key performance indicators analysis

Many large Chinese cities are constructing metro systems in order to solve the problems in traffic. A productive and effective way to optimize and integrate the bus network with metro systems is required to form a unified city transit network. This study introduces a method to evaluate the transit network bus route optimization based on key performance indicators, which takes into consideration three interest groups: transit operators, passengers and transit management agency. This study has been applied in Chongqing transit bus network optimization and integration along the metro corridors. The results show that this method well balances network efficiency and the benefits of companies and of passengers.
