The results suggest that high density and mixture level in the neighborhood are positively related to their daily experience with residence and travel, but the higher density in workplace negatively influents residential satisfaction. Social environment is of great significance to intercity commuters. Life domain satisfaction (including travel, leisure, and residential satisfaction) mediates the relationship between the neighborhood environment and life satisfaction. Travel and leisure satisfaction affect residential satisfaction, which in turn affect life satisfaction.
