The Corona epidemic is one of the most important issues in the world today, which has significantly changed urban transportation and highlighted the weaknesses of current transportation methods. This crisis has provided a unique opportunity to redesign urban transportation programs in a more sustainable and resistant way. The main goal of the recent research is to evaluate the impact of contextual factors in the development of active transportation during the Corona epidemic in Durood City. This research is of an applied type and based on the descriptive-analytical method, and with the help of a questionnaire, the researcher investigated the effect of background factors such as age, gender, education, etc. on active transportation during the Corona epidemic. The use of structural equation modelling has been investigated. The statistical population of the research includes 180 residents of Durood City, which was calculated using the required software and with a confidence level of 95%. The analysis of the resulting findings shows that among the factors affecting the development of active transportation during the Corona epidemic, social and health factors with the highest factor load are the most effective factors, and among the background factors affecting the development of active transportation, age is the most influential and Household income had the least influence on the choice of active transportation during the outbreak of the Corona epidemic. The final results indicate that the background factors during the outbreak of this epidemic in Durood City greatly affected the development of active transportation during this period.
Extended Abstract
Introduction
COVID-19 is an infectious disease caused by the acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) has classified this epidemic as a global epidemic (Wielechowski et al, 2020:1). The COVID-19 epidemic has severely affected many social and economic activities, transportation being one of them (Przybylowski et al, 2021:8). Unprecedented measures such as travel restrictions and gathering restrictions implemented by many countries are one of the most significant impacts the pandemic has had on transportation. And the act to observe social distancing during the COVID-19 pandemic was a sudden restriction that, along with a sharp reduction in travel volume and changes in activity patterns, contributed to sudden changes in the way of transportation in cities around the world (Ciuffini et al, 2021:3). . As a result, rapid and intense changes in people's movement styles (that is, lifestyle about mobility, travel habits, etc.) appear from other aspects of their behaviour in travel. Movement styles are usually resistant to change under normal circumstances, but necessarily during a prolonged and severe pandemic, the unique circumstances introduced by this new pandemic will change many habits and preferences. re-examine themselves and as a result, significant changes are made in people's methods (Shamshiripour et al, 2020:1). Therefore, the relationship between transportation and diseases, as well as how it affects travel behaviour, has been investigated. Following these cases, it is also very important to understand the effects of the pandemic on travel demand (Dingil & Esztergár-Kiss, 2021:1). One of the most important topics of the day is to examine the issues related to the effects of the Corona epidemic on cities. One of these issues is related to the change in the use of transportation in cities, due to the various measures taken by the government to control this epidemic, the amount of transportation during the quarantine period using other means of transportation has decreased and people are facing problems. Moved towards the use of active transport. In this research, using the structural equation model, the effect of factors such as age, gender, education, distance from the city centre, and family income on the components of active transportation during the corona epidemic was investigated, and finally, a model was drawn that the relationship between shows them. and shows the most effective factors.
 
Methodology
 The current research method is descriptive-analytical and applied in terms of purpose. Data collection has been done using the field method and questionnaire tool and its random distribution in the areas of Durood City. The statistical population of this research includes Durood City with a population of 121,638 people. The sample size was calculated using sample power software with a confidence level of 95% and a possible error of 5% from 180 people. To explain and model the effects, structural equation modelling (SEM) was used in Amos software. Cronbach's alpha test was used to measure the reliability of the research tool, which was taken separately for each of the main indicators.
 
Results and discussion
In this part of the research, the findings have been analyzed and the research hypotheses have been answered. Structural equation modelling has been used for the scientific analysis of this research. The findings of this hypothesis, which shows the influence of background factors in the development of active transportation during the epidemic period, show that the social factor and health with a factor weight of 0.94 have the highest factor load, followed by the social factor with factor A. The economic coefficient of 0.94 ranks second and the economic coefficient of 0.60 has the lowest factor load. Among the relevant factors, age with a factor load of 0.68 is the most effective factor, and distance from the city centre is the second most effective factor, followed by gender and education, and finally, household income is the most effective factor. The coefficient of 0.18 had the least effect on the choice of active transportation during the outbreak of the Corona epidemic.
 
Conclusion
The sudden spread of the corona epidemic in the world has severely affected transportation, these effects have made people use active means of transportation, which can have the greatest effect in controlling this epidemic. And active transmission can be a key strategy to reverse the burden of communicable diseases that require social distancing. In the structural equation model that examines the impact of background factors on the development of active transportation, the results show that among the background factors, age is the most important factor, and with increasing age, the use of active transportation, especially bicycles. is. The ride is less. The second most effective factor in choosing active transportation during the Corona epidemic is the distance from the city centre. This factor indicates active transportation planning in medium and small cities where the residence is less far from the workplace or the city centre. They will be more successful. Gender, the next influential factor in this research, shows that women use bicycles less and walk more. It is the opposite for men. Education and income are also affected in the next categories, which shows that the level of education of individuals or household income can also have important effects on choosing the type of transportation during the epidemic. Finally, background factors have had a significant impact on the spread of Corona in Durood City. Finally, during this pandemic, countries face an opportunity to revise strategic goals to reduce the risk of increasing active transportation infrastructure. The path to sustainability can be improved by temporary measures that enable the increase of active transport, and this epidemic and its medium- and long-term consequences compel us to propose an emerging research program to investigate sustainable and healthy urban mobility with comprehensive guidelines. do. Epidemic diseases in the future, it is necessary to pay attention to the fact that today's policies may have long-term consequences.
