The open-ended questions and number of constructs.

		Phase 1		Phase 2			Phase 3
Summary	The experts were asked to share their opinions about opportunities and challenges relevant to the impacts of the COVID-19 outbreak on the dimensions of sustainability of shared mobility at travel behavior and urban infrastructure levels.			As all items required prioritization and ranking in order of importance and impact a quantitative assessment was carried out. The importance and patterns of result distribution were statistically measured by using a five-point Likert scale.			The third phase involved the modification and finalization of the rankings performed in the previous phases to considerably improve the quality of the responses.
Response rate	18 out of 21 (85.71 %)			18 out of 18 (100 %)			18 out of 18 (100 %)
Outcomes	By coding the responses, 36 independent constructs were elicited through the sub-questions, that were categorized within three dimensions of sustainability.			Constructs whose mean group value was 4.5 or above were considered the most important items identified by the expert panel.			Of the 18 participants, four slightly modified their scoring, whereas the rest verified their previous ratings. As a result, “A boom in online shopping” and “Handling crowds” were could not hold their ranks, but no new construct was added to the list.
