The application of computer technology has enabled China's motorways to develop from manual toll collection to the current electronic non-stop toll collection, gradually forming a planned overall road network toll collection mode. In order to improve the efficiency and service quality of motorways, all provinces in China are planning to set up network toll collection systems, which can improve the shortcomings of the old toll collection methods to the maximum extent possible, unify the motorway network as a whole and ensure the smooth flow of vehicles within the network. Based on this, this paper presents a comprehensive account of the research and development of highway network toll collection systems. By introducing the composition and form of highway network toll collection systems, it outlines the construction and development stages of network toll collection systems, focuses on the key technologies in each stage, summarises and analyses the development trend of highway network toll collection systems in the light of the current research status, and outlooks on the future development trend.
