Classic transportation design is not suitable in this pandemic era. A new design that fits a new era is required, revolving around human-machine-environment relationships and ergonomics. This paper proposes a different way for modular transit to be used in the new environment. A calculation is made to provide analysis that modular vehicles have a significant traffic efficiency impact on the traditional transit system. In addition, the concept of modular transit used in the new environment is different from its usual function. The discussion shows that modular transit has higher passenger loading efficiency than classic transportation. Furthermore, the study simulates various scenarios of modular transit, showing its capability. The result verifies that modular transit will further improve new environment traffic efficiency.
