Public transportation plays a significant role in decreasing energy consumption and greenhouse gases. By reducing private passenger vehicles, lowering vehicle traffics, and decreasing travel distances via public transport, millions of liters of gasoline can be saved and carbon dioxide emissions may be prevented. But in order to achieve these public transport goals, it faces numerous economic, political, managerial, infrastructure, and other barriers among which physical barriers are more tangible than others. Among the physical barriers to public transportation fleets, especially vehicles physics, are more prominent. The present study aims to investigate and analyze the barriers to public transportation fleet development in Ahvaz metropolis with emphasis on the physical barriers of the vehicles. The main research approach is developmental-applied, descriptive, analytical, and survey research. The research data were collected through documentary, library, survey techniques, and interviewing with individuals and experts. The ARAS decision-making method was used to rank the barriers and the Kriging model to map these barriers to the city. The findings indicated that barriers in each bus and taxi use have different effect sizes in such a way that for taxi use, fleet deficiency (with the weight of 0.0161), poor quality of interior hygiene (with the weight of 0.074) and poor diversity (with the weight of 0.066) have the most effect sizes; while for bus use, fleet burnout, poor heating-cooling system, and low safety (with common weights of 0.0116) have the greatest effects. Zoning these barriers in the city revealed that most of the city area is very inappropriate range, and districts 2 and 5 are the most appropriate and inappropriate zones, respectively.
