Current article is developed in the frame of the postdoctoral project: “Adapting the public transport system to the COVID-19 challenge, ensuring its sustainability” under activity 1.1.1.2 “Post-doctoral Research Aid” of the Specific Objective 1.1.1 “To increase the research and innovative capacity of scientific institutions of Latvia and the ability to attract external financing, investing in human resources and infrastructure” of the Operational Programme “Growth and Employment”. That is why the primary goal here is to develop post-doctorate skills as a new scientist and to increase post-doctorate scientific capacity, ensuring the possibilities for starting serious career in scientific institutions. The secondary goal of current article is to disseminate the information about the start of current project and about the scientific plans of the post-doctorate to develop a system solution for keeping public transport system in sustainable and safe position by adapting it to the COVID-19 challenge, ensuring its sustainability. The first step of adapting the public transport system to the COVID-19 challenge, ensuring its sustainability is given here. The recommendations and measures done during first wave of coronavirus are structured and described. There are shown also the most common mistakes (in an unstable epidemiological situation) made while using a transport. Recommendations to reduce the negative effect of coronavirus COVID-19 in transport are given. Advanced practices and last achievements for controlling coronavirus COVID-19 to reduce its negative effect in public transport system are discussed.
