Urban public transport systems must be economically efficient and additionally environmentally sustainable. Available decision support systems, including multiple criteria decision models, allow identifying which urban public transport vehicles are acceptable and those that should no longer be used in efficient and environmentally friendly cities. Previous research has ranked urban public transport vehicles by applying analytic hierarchy process multi-criteria decision-making models, from economic and non-polluting perspectives. However, until now, the types of vehicles acceptable for fleet renewal have not been identified. This study proposes a consistent combination of the ELECTRE TRI multiple criteria decision sorting method and the DELPHI procedure, the objective of which is to identify which urban public transport vehicles are acceptable, taking into consideration a suggested sustainable threshold, which includes economic and environmental strict requirements. The proposed model is based on 2020 Madrid urban public road transport data, published by Madrid City Council, which were compiled by the authors, and assessed by a panel of 20 experts to identify criteria and factors included in the model. Findings help local administrations to identify which urban public transport vehicles should be progressively replaced by those classified as economically efficient and additionally environmentally sustainable.

可持续城市公共交通系统的多准则决策分析

城市公共交通系统必须经济高效，而且环境可持续。可用的决策支持系统，包括多标准决策模型，可以确定哪些城市公共交通车辆是可以接受的，哪些不应再用于高效和环保的城市。先前的研究通过应用层次分析法多标准决策模型，从经济和无污染的角度对城市公共交通车辆进行了排名。然而，到目前为止，车队更新可接受的车辆类型尚未确定。本研究提出了 ELECRE TRI 多标准决策排序方法和 DELPHI 程序的一致组合，其目的是确定哪些城市公共交通车辆是可以接受的，考虑到建议的可持续阈值，其中包括经济和环境的严格要求。提议的模型基于马德里市议会发布的 2020 年马德里城市公共道路交通数据，该数据由作者编制，并由 20 名专家组成的小组进行评估，以确定模型中包含的标准和因素。调查结果有助于地方行政部门确定哪些城市公共交通车辆应该逐渐被那些被归类为经济高效且环境可持续的车辆所取代。并由 20 名专家组成的小组进行评估，以确定模型中包含的标准和因素。调查结果有助于地方行政部门确定哪些城市公共交通车辆应该逐渐被那些被归类为经济高效且环境可持续的车辆所取代。并由 20 名专家组成的小组进行评估，以确定模型中包含的标准和因素。调查结果有助于地方行政部门确定哪些城市公共交通车辆应该逐渐被那些被归类为经济高效且环境可持续的车辆所取代。
