Qatar residents' satisfaction for using the Doha Metro Rail System: An analysis for sustainable transportation.

Doha's public transportation system was entirely dependent on publicly run ground transportation services, including buses, taxis, and limousines before the Doha Metro Rail System - a sustainable transportation system, was implemented. This study integrated the Social Exchange Theory (SET) with the SERVQUAL 5 dimensions as a higher-ordered construct to assess how satisfied Qatar residents were with the Doha Metro Rail System after three years of service. To encourage commuters to use sustainable public transportation, it is imperative to design methods to assess public travel satisfaction concerning public transportation use as Qatar moves toward a sustainable public transportation system.
