The article considers an actual problem of organizing a safe and sustainable urban transport system. We have examined the existing positive global experience in both infrastructural and managerial decisions. Then to assess possible solutions at the stage of infrastructure design, we have developed the simulation micromodels of transport network sections of the medium-sized city (Naberezhnye Chelny) with a rectangular building type. The models make it possible to determine the optimal parameters of the traffic flow, under which pollutant emissions from cars would not lead to high concentrations of pollutants. Also, the model allows to obtain the calculated values of the volume of emissions of pollutants and the parameters of the traffic flow (speed, time of passage of the section, etc.). On specific examples, the proposed method’s effectiveness is shown. Case studies of cities of different sizes and layouts are implementation examples and possible uses proposed by the models. This study has shown the rationality of the suggested solution at the stage of assessing infrastructure projects and choosing the best option for sustainable transport development. The proposed research method is universal and can be applied in any city.

The purpose of the current study is to raise the question about making a comparison between international legislation in the United States, European Union, and legislation of Saudi Arabia derived from Islamic law regarding the poultry slaughtering process and the relationship of that to achieving safe and healthy food for humans. In addition, the study utilized the Holy Qur’an and the texts of the Prophet’s hadith as primary sources. Additionally, various national and international laws, reports, and legislations were referenced as secondary sources for the review. Moreover, this study addresses a research gap by providing a comparative analysis that links Islamic and international legislation regarding poultry slaughter and examines its impact on food quality and safety. The study’s findings indicate that Islamic Sharia provisions are in harmony with the regulations of the Kingdom of Saudi Arabia related to poultry slaughtering process. This alignment ensures the primary goal of the slaughter process, which is to quickly get rid of the blood and achieve the well-being of the poultry. Consequently, this results in high quality meat with low microbial content that can be preserved for a longer period compared to regulations in other global markets such as the USA and the European Union.
