Research on performance evaluation system of highway quality improvement and maintenance under PPP mode:take national and provincial trunk lines in Heilongjiang Province as an example
As the core component of highway transportation system,national and provincial trunk highways have played a crucial role in promoting social and economic benefits and regional economic construction.In order to improve the quality of ordinary national and provincial trunk highways as well as strengthen the maintenance work in the later stage,This paper constructs a highway operation period performance evaluation system(HOES)based on the PPP model from five dimensions of pavement quality index(PQI),project output,project benefits,project management,and random evaluation,which makes the government expenditures rationalized,allows for a comprehensive understanding of the operation status,and improves the regulatory efficiency.Taking Heilongjiang national and provincial trunk lines as an example,the performance evaluation of the highways during their operation period in 2022 was conducted.The results showed that the performance evaluation in the eastern and western regions of Heilongjiang Province met the requirements of the system and no deduction is needed;the PQI in the eastern region is 96.89 and the PQI in the western region is 96.96,both lower than the stipulated 98,which indicates that there are certain deficiencies in the pavement maintenance in the eastern region and the western region and that is the the focus of the next maintenance improvement work.
