Evaluation of public and private traffic safety performance under regional perspective differences in China

With the ongoing advancement of social and economic, it is imperative to facilitate the enhanced integration of high-quality development and high-level safety within the road transportation industry, thereby contributing to the progression of economic infrastructure. This study takes 30 provinces in China as the object, quantitatively measures the efficiency of traffic expenditure - road safety application stage from 2011 to 2020 by MPT-SUD SBM model, and analyzes the difference of technical level efficiency of each province combined with the technology gap ratio. The results show that: 1) The total performance of public-private transportation expenditure and road safety application stage in China shows an increasing trend from 2011 to 2020. 2) There are differences in the level of road safety performance among different provinces. 3) The technology gap ratio reveals that there is still a certain regional imbalance in road safety technology in China.
