基于效率和公平的区域协调发展战略下综合交通网评价指标和方法研究OA

Overall coordination of efficiency and fairness is the basis and an inevitable requirement for objectively and comprehensively evaluating the effectiveness of integrated transportation network development under the regional coordinated development strategy.The scale of transportation infrastructure was employed to represent efficiency,and the differences in comprehensive transportation infrastructure density among the four major regions were employed to represent fairness.Covering multiple transportation modes such as railways,highways,and airports,and comprehensively considering efficiency and fairness,an evaluation indicator system of the integrated transportation network under the regional coordinated development strategy was established.The dimensionless method was used to aggregate infrastructure indicators of different transportation modes under efficiency and fairness.Transportation efficiency scores and fairness scores were standardized using distance-based methods.Weight coefficients were used to represent the preferences of different evaluators for efficiency and fairness.The development of the integrated transportation network in China under the regional coordinated development strategy since 2000 was taken as an example to verify the effectiveness and practicality of the proposed model and method.The results indicate that the model can be used to evaluate the effectiveness of integrated transportation network development under China's regional coordinated development strategy,and that the weight coefficient affects evaluators'assessments of regional transportation network development effectiveness.Under a uniform distribution of evaluators'preferences for efficiency and fairness,transportation development in 2023 has a 54.5%probability of being the optimal solution,while transportation development in 2005 has a 45.5%probability of being the optimal solution.
