| Abstract: | To achieve the sustainable development goal of the urban passenger transport system, a bi-objective optimization model for maximizing the traffic efficiency and minimizing the internal cost of the system was established based on the economic sustainability, the social sustainability and the environmental sustainability. The correctness of the model was verified. Taking Changchun city as an example and solving it with the ideal point method, the optimized structure reflects the sustainable development goal of an urban passenger transport system. |
