The transportation sector consumes 21% of the global final energy consumption, and the growing global economy will likely increase the need for transport. Furthermore, it will likely contribute to increasing greenhouse gas (GHG) emissions in the future without proper mitigation efforts. Related to this issue, the Avoid-Shift-Improve (A-S-I) framework is one approach that can be used to achieve sustainability in the transportation sector, particularly in urban transportation. In this work, we simulate the development of public transportation network and vehicle electrification strategies related to the framework using a dynamic model with a case study in the Greater Jakarta Area in Indonesia. Our results show that the framework can simultaneously reduce energy consumption and GHG emissions. Furthermore, we found that there is an interaction between the public transportation network development and vehicle electrification, in that increasing the use of public transportation could potentially have a negative effect on electric vehicle use.
