چکیده
ظهور بیماری های واگیردار جدید عفونی به یک مشکل جدی جهانی تبدیل شده است و شبکه های حمل و نقل عمومی عامل مهمی در زمینه گسترش سریع اینگونه بیماری ها می باشند. در این مقاله، مدلسازی انتشار ویروس کووید-19 COVID-19)) با بکارگیری مدل ریاضی دینامیکی شناحته شده با نام SIR برای افراد مستعد به آلودگی (Susceptible)، آلوده (Infected) و بهبود یافته (Recovered)، با استفاده از نرم افزار MATLAB انجام پذیرفته است. این مطالعه با استفاده از آمار دقیق موارد مبتلایان و مرگ و میر ناشی از ویروس کرونا در ایران در بازه های زمانی مشخص، به تاثیرسیستم های حمل و نقل ریلی، هوایی و جاده ای بر انتشار ویروس کرونا از مبداء شهر تهران به مقصد شهرهای مشهد و شیراز پرداخته است. براساس نتایج این مطالعه، میانگین نرخ شیوع ویروس کرونا در ماه های فروردین و اردیبهشت سال های 1399 و 1400، برای سیستم های حمل و نقل ریلی، هوایی و جاده ای به ترتیب از مبداء تهران به مقصد مشهد برابر با 10/2، 11/2 و 16/2 و برای مبداء تهران به مقصد شیراز برابر با 09/2، 10/2 و 12/2می باشد. با توجه به آمار مبتلایان و مرگ و میر مسافران تهران به مشهد و تهران به شیراز و همچنین نرخ شیوع محاسبه شده، نتایج حاکی از ایمن تر بودن سفرها ازنظر شیوع ویروس کووید- 19 با سیستم حمل و نقل ریلی نسبت به حمل و نقل هوایی و جاده ای و همچنین حمل و نقل هوایی نسبت به حمل و نقل جاده ای می باشد.

چکیده English

The appearance of new infectious diseases has become a serious global problem. Public transportation networks are an important factor in the rapid spread of such diseases. In this study, investigation of the spread of COVID-19 epidemic virus is done using dynamic SIR (Susceptible – Infected – Recovered) mathematical model with MATLAB. In addition, we studied accurate statistics of infected cases and deaths due to COVID-19 for the time intervals in various transportations in Iran, for instance, the transportation via rail, air and road transportation in specific time periods from Tehran city to Mashhad city also Tehran to Shiraz. Average of the Reproductive number (R0) COVID-19 in Farvardin and Ordibehesht months of 1399 also 1400 for Tehran to Mashhad is about 2.10 for rail transportation, 2.11 for air transportation and 2.16 for road transportation also for Tehran to Shiraz is about 2.09 for rail transportation, 2.10 for air transportation and 2.12 for road transportation. In each transportation type, the modelling is done and the comparison based on the statistics of deaths of passengers from Tehran to Mashhad and Shiraz shows the risks of outbreak and infection in road transportation are higher than air and rail transportation and the risks of outbreaks and infection in air transportation are higher than rail transportation. This results indicate that rail transport in safer in terms of the prevalence of COVID-19 and the contamination from air and road transportation.
