Every year, a significant number of our compatriots in Iran are killed or injured in road accidents, resulting in heavy damages to society and the country. With population growth and road traffic, the financial costs of accidents are imposed on families and the government, in addition to the irreparable psychological and social damages. Human factors, vehicles, roads, and natural elements are the main contributors to unsafe traffic conditions. The traffic safety index serves as a suitable measure for evaluating the safety level of countries. The objective of this research is to compare Iran's traffic safety index with that of Central and East Asian countries. When comparing Iran with East Asian countries, it should be noted that each country has its unique characteristics and approaches to road safety. East Asian countries such as South Korea, Japan, China, and Singapore have implemented various measures to address road safety issues, including infrastructure improvement, stricter regulations, advanced technologies, and public awareness campaigns. As a result, these countries have experienced varying degrees of success in reducing road accidents and casualties. Based on index calculations, Iran has unfavorable and concerning conditions compared to most Central and East Asian countries, and therefore, more attention and effort are needed to improve road safety and reduce the number of accidents.

Over the past 10 years, the performance of airlines in the passenger domain has been influenced by various factors. Consequently, numerous studies have been conducted worldwide on the factors affecting the performance of airlines in passenger services, and Iran has also seen significant statistical studies in this regard. In this research, an attempt has been made to conduct a comparative analysis of the years 2012 to 2022 for Iranian airlines in the passenger domain, using defined statistical indices. The defined indices in this study include passenger density on each flight, the percentage of delayed flights, the percentage of canceled flights, and the number of flights passing through the country's airspace. It was observed that Iran had acceptable performance in three indices until the onset of the COVID-19 pandemic. However, after the pandemic, due to lack of planning and readiness for unforeseen events like COVID-19, the airline performance has been severely impacted. Hence, airlines need effective planning and strategies to prevent the adverse effects of unforeseen events such as the COVID-19 pandemic. Overall, the developments of this decade highlight the need for flexibility and the ability to respond to challenges in the aviation and air transportation industry
