Evolution and Practice of the Shenzhen Comprehensive Transportation Model System
Transportation models have been developed for more than 40 years in China.Numerous cities such as Beijing,Shanghai,Guangzhou and Shenzhen have established transportation model systems which play significant roles in practice.In response to the new trend and demand in the development of transpor-tation models,Shenzhen has initiated research and practice on the new generation of comprehensive trans-portation model system.Based on the previous work,the framework of comprehensive transportation mod-el system has been refined,the application scenarios have been expanded,the model usage processes have been reconstructed,and the availability of the transportation model data has been enhanced.The main work includes two parts.Firstly,the overall goal,functional design,system and platform design scheme of the new generation of Shenzhen comprehensive transportation model system is put forward.Secondly,the research and platform construction practice for Shenzhen's new generation comprehensive transportation model system was initiated,including the construction of the tour-based transportation planning model,the construction of the multi-agent operation model,the construction of the cloud-based transportation model platform,and the SuTPC platform based on digital twin technology.The evolution and practice of compre-hensive transportation model technology provide more efficient support for the current diversified applica-tion scenarios of urban transportation and more friendly application services for different model users.
