Initiatives in Dili of Timor-Leste for implementing traffic management using digital twin-BIM technology

Abstract

Dili, the capital of Timor-Leste, is facing the environmental and economic impacts of increasing urbanization, including traffic congestion, and a deteriorating atmospheric environment. To solve these situations, an evidence-based traffic management policy (EBTMP) based on a digital twin (DT) technology that combines geographical information and construction information modeling (BIM) is essential. This research successfully identified traffic patterns, delays, congestion hotspots, and air pol-lutants such as CO₂, NOx, and PM10 in the target zone the so-called Cathedral zone. Motorcycles were found to be an important contributor to air pollution due to their widespread use. Therefore, it is important to reduce motorcycle users in the future to reduce air pollution. Besides, the most important thing is to take action to provide good public transportation facilities and infrastructure to reduce private transportation users. By doing this, Dili’s urban mobility will be improved.
