Abstract
Urban rail transit project is a kind of typical operating public project. Adopting the PPP model can alleviate local financial pressure and improve capital use efficiency. However, many existing urban rail transit PPP projects have fallen into the dilemma of cost overrun, schedule delay, and poor product quality. The lack of reasonable project performance evaluation is considered as an important cause. This research first clarifies the meaning and characteristics of project performance evaluation by comparing and analyzing several basic concepts and relationships. Secondly, an operation performance evaluation system based on urban rail transit PPP project of a three party is constructed from a multistakeholder perspective. Finally, the best worst method and large-scale group evaluation technology are used based on the comparison of multistakeholder evaluation application scenarios and evaluation methods. A quantitative model is constructed to evaluate the operating performance of urban rail transit PPP projects and is tested and explained by a specific case study. Most current studies generally focus on the earlier stage of project performance, and this article mainly discusses and researches the operation performance of PPP projects. There, suggestions are provided for the operation performance evaluation theory and urban rail transit PPP project practices. This article focuses on the operation performance evaluation of PPP projects.

Stakeholders are classified in prior, rather than identified using the evaluation information. It is challenging for methods mentioned above to process large-scale evaluation data, and most of the objective weighting methods based on data feature classification can hardly perform satisfyingly. In response to these two problems, Rezaei proposed a new multicriteria decisionmaking method—the best worst method (BWM) [34]. e decision maker finds the best and most important criteria and the worst and least important criteria in the criteria group according to the ultimate target. en, pairwise comparisons are conducted between the best worst criteria and other criteria. e maximum nonlinear programming problem is constructed according to the judgment vector. e weight of each criteria corresponding to the final goal can be obtained
With 24 stations in total, it connects essential facilities and transportation hubs such as well-known universities, Zhongguancun Science and Technology Park, Xidan Commercial District, places of interest, and Beijing South Railway Station. e overall planned investment for the Beijing Metro Line 4 project is about 15 billion yuan. e project officially started in August 2004 with a construction period of 5 years. e project completed and opened for trial operation in September 2009, and until the end of 2019, it has been in operation for more than ten years
Summary
With the China’s economic development and the acceleration of urbanization, the number of urban populations and cities’ scale continues to expand. Citizens’ demand for urban transportation increases continuously, and the number of private cars in urban area rises significantly. Ese problems seriously threaten citizens’ living standards and the development sustainability of the city [1]. The travel mode represented by private cars has caused many urban problems: traffic congestion, energy consumption, greenhouse gas emissions, and air pollution caused by automobile exhaust. To solve these problems, the government hopes to reduce private car ownerships and replace private car travel by increasing the public transport supply. Public transportation is widely favored by the government and society, and it is regarded as an essential measure to solve urban traffic problems [2]
