Digital twin enabled sustainable urban road planning

Sustainable urban road planning should endeavor to meet current and future traffic-related demands achieve financial, environmental, social benefits, which is a complex interdisciplinary issue that needs consider various factors data. Multi-criteria decision making (MCDM) can provide reasonable solutions, some existing studies integrated MCDM with geographic information system (GIS) technology. This paper presents an approach based on digital twin (DT), MCDM, GIS called DT-MCDM-GIS framework. DT digitalize the physical world data for whole process; criteria evaluation methods; environment analysis. Building demolition land use, traffic congestion, driving route selection habits, air quality, noise are all considered in framework planning. The proposed functional, economic, people-friendly, eco-friendly scheme considering new construction old widening alleviate congestion alternative drivers conforms their habits.
