Abstract

With the spread of the Corona epidemic, there was a big change in urban life, of which the transportation system was one of the main focuses. The sustainability of the transportation system is considered one of the most basic challenges of urban management, especially in metropolises, whose consequences can include a wide range of environmental, social, economic, etc. risks. Based on this, this research aims to cross-sectionally investigate the level of sustainability of the transportation system among the users of line 7 of Tehran's fast bus system and investigate its differences in four sub-indexes of travel management, travel demand, travel behavior and travel pattern The results of the research, which is the result of 400 samples using a non-random-quota method and using an independent one-sample t-test, show that instability is evident before the epidemic, and the statistical average of the sub-indices is 2.82, while during The epidemic tends towards stability and its mean increases to 3.93, which indicates quite acceptable stability. After the outbreak of the epidemic, the average stability is slightly reduced, but it is still evaluated at a relatively acceptable level, which means that the average of the items with a number of 3.58 is significantly different from before the epidemic. Also, the results show that the "travel demand" sub-index has the highest average (with a number of 3.65) among other sub-indexes and is more stable, and the "travel behavior" sub-index or the total average of 3.33 has the lowest score.
