Annually, Iran experiences numerous fatal and financial accidents due to traffic collisions, emphasizing the need for effective strategic plans and prevention measures.This article examines the indicators of suburban traffic safety in Iran and compares them with Asian countries. In this article, key concepts of suburban traffic safety, including speed, seat belt usage, braking systems, etc., are investigated. Then, the indicators of suburban traffic safety in Iran and Asian countries are examined. Finally, based on data and statistics, the differences in traffic safety between Iran and Asian countries are discussed. In this study, traffic safety indicators such as the ratio of fatalities to road length, the ratio of injuries to road length, and the ratio of injuries to fatalities are examined. By examining these indicators in Iran and advanced and wealthy Asian countries, it is suggested that by improving vehicle safety, increasing road length, enforcing stricter laws, etc., steps can be taken to improve traffic safety indicators.

This article examines the effect of human error in aviation accidents. Aviation accidents are one of the most important factors that threaten security in air transportation, and various factors can play a role in their occurrence. One of these factors is human error, which can lead to an accident from simple to serious and uncorrectable errors, also human error is one of the important factors in plane accidents that can have serious consequences for the health and safety of passengers and aircraft employees. It may occur at any stage of the flight process from design and manufacturing to flight operations and maintenance. In the flight operations phase, this error can include pilot and air traffic control errors, ground logistics errors (such as lack of proper maintenance and repair of aircraft), and flight crew performance errors. It is clear that the detailed investigation of human errors in aviation accidents plays a significant role in increasing the safety of flights and may lead to effective improvements in the fields of pilot training and aircraft systems design. The purpose of this article is to analyze the human error in aviation accidents and the factors affecting its occurrence, which can help improve the safety and performance of airplanes and thus save people's lives in aviation accidents.

Road geometry consists of horizontal and elevation components of road extensions, which mainly include tangent lines, arcs and connection curves. The role of these components in guiding the driver as well as his prior knowledge of the continuation of the road is very important. Also, the arrangement and combination of these components can have a positive or accidental effect on the safety and comfort of the driver. Horizontal curves are considered as one of the most accident-prone points of the road. Centrifugal force on vehicles and human error are the two main factors in the occurrence of accidents in these areas and will eventually lead to overturning or slipping of vehicles. In this study, the main goal is to find a way to increase safety and reduce the rate of accidents due to the relationship between human factors and road geometry. Which is mostly based on previous research and analysis. Studies on safety measures to increase safety in recent years have been collected and reviewed. The results show that the review of new methods, models and schemes such as risk reduction plan to support decisions, safety performance prediction methods on horizontal curves such as Safety Performance Function (SPF) in the future will help better performance for users. The road guarantees. Also, using short-term economic solutions such as route marking will increase safety. On the other hand, the most important criteria for assessing the safety of the vehicle when passing the corner is to estimate the resistance of the vehicle against frustration and overturning, which is also important.
