METHODOLOGY

Strategies for wind drag reduction
Research by (Yang et al., 2021) highlights the need for engineering assessments to
determine whether bus structures can support the weight of green roofs, including
soil, plants, and irrigation systems. Structural feasibility needs to be considered
when evaluating the installation of green roofs on buses. According to this study,
recommended to apply lightweight materials and innovative green roof designs to
minimize the weight while ensuring safety and performance. The same purpose as
emphasized by Huang and Zhang, 2022 that advancements in materials can provide
solutions that enhance the structural capacity of buses without causing negative effects ABOUT THE INVESTIGATOR
