This research developed a set of ecological indicators for urban roadway rating system along with their requirements. Current roadway sustainability rating systems such as Greenroads, Taiwan’s roadway design considerations, and ecological construction methods were analyzed to incorporate ecological issues and requirements. The ecological indicators found suitable for Taiwan’s urban roadway are ecological impact analysis, green intensity, vegetation quality, stormwater best management practices (BMPs) and landscape. After interviewing designers for opinions, the indicator checklists were produced. Ecological impact analysis evaluates the ecological impacts of a project on the environment. Green intensity aims to increase the roadway’s green area and increase the visual quality of a roadway. Vegetation quality is to reduce the impact of invasive vegetation species and improve biodiversity. BMPs help to reduce stormwater flow impacts and improve the water quality of stormwater runoff. Landscape enhances users’ visual experience through visual improvements along the roadway. Each ecological indicator has its own checklist and was verified by using data samples. The results indicate that the checklists are applicable and comply with the regulations for urban roadways in Taiwan.
