This study highlights transportation service quality (including that of the core transportation service and the physical environment of transportation) and investigates its impact on satisfaction as well as attitude toward and image of a sustainable city. Additionally, this study also addresses the mediating role of satisfaction in the relationships between transportation service quality, and both attitude toward and image of a sustainable city, as well as the moderating role of involvement in the links between satisfaction and this attitude and between satisfaction and this image. The findings confirm that both core transportation service and the physical environment of transportation significantly and positively influence satisfaction and, in turn, significantly and positively influence attitude toward and image of a sustainable city. Satisfaction also plays a mediating role in the links between transportation service quality and this attitude and image. In addition, the effect of satisfaction on attitude toward and image of a sustainable city becomes greater as the level of involvement increases.
