Duolun Technology (603528.SH) stated on the interactive platform that the company's intelligent transportation sector has been researching and developing in the field of intelligent connected automobiles for many years and has a certain amount of technical accumulation. The company mentioned relevant technology and projects related to vehicle-road collaboration in its 2020 and 2023 annual reports, such as:"The company actively seizes the opportunity of industrial transformation and upgrading, strengthens product R&D and marketing, researches and develops a variety of new transportation integration products, such as intersection adaptive signal lights and intersection edge computing units, launches a new generation of intelligent transportation signal cloud control platform, supports multi-level signal adaptive optimization, multi-scene contingency plan control, multi-source data fusion evaluation, vehicle-road collaboration services and other applications." In addition, the integrated combat platform and intelligent inspection station prevention and control platform have also been successively launched and applied, and the business coverage continues to expand. The company continues to increase its focus on innovative business such as intelligent network connection, accelerates cooperation with scientific research institutes and industry chains, and collaborates with partners to create vehicle-road collaboration testing and demonstration scenarios, promoting the rapid development of the industry. During the reporting period, the company obtained many patents related to vehicle-road collaboration, and jointly developed the "multi-mode active collaboration technology and application based on vehicular edge networks" with Nanjing University of Posts and Telecommunications, which received high industry recognition and was selected as the vice-chairman unit of the "Jiangsu Province Intelligent Connected Automobile Industry Innovation Alliance". The company actively participated in the application research of vehicle-road collaboration and successfully applied for the major science and technology project in Nanjing in 2023, "Key core technology of city smart transportation vehicle-road collaboration based on holographic perception and intelligent decision-making". The project, led by Duolun Technology, jointly carried out key technology research and development with Jinling College of Nanjing University of Posts and Telecommunications and Southeast University, and jointly completed the testing and application of relevant technical achievements with China United Network Communications and Zhongdian Car Union Information Security Technology Co., Ltd. The project has a period of three years and focuses on the key issues of urban traffic management, such as "multi-component interconnection and multi-element fusion perception mechanism of urban traffic vehicle-road collaboration" and "vehicle-road cloud system perception-communication-computation-decision-making information interaction mechanism and optimization method". It aims to overcome key technologies based on holographic perception and intelligent decision-making, supported by roadside equipment and cloud control platforms integrated with on-board information terminal equipment, to help promote the foundation and collaborative development of industries such as self-driving and vehicle-road collaboration in Nanjing.
