Abstract：In order to build a new generation of intelligent transportation system,promote the application of the'multi-source perception fusion'system architecture in urban smart transportation.Based on the Yiyuan Tunnel in Shandong Province,an intelligent tunnel digital twin system is built,through the deep integration of Internet of Things technology and traffic engineering technology system,and with the help of data mining technology,the system realizes real-time trajectory tracking of lane-level vehicles based on license plate information,as well as real-time tracking,positioning,precise control and pre-warning functions of key vehicles such as'two passengers and one danger'.The practical results show that in the actual tunnel traffic environment,the system can efficiently monitor the traffic flow status,the overall delay is controlled within 3 s,the statistical accuracy of traffic flow reaches 95%,and the accuracy of vehicle trajectory reaches 90%.The digital twin system provides a reference for the upgrading and transformation of transportation facilities such as highway tunnels in China.
