The traffic situation is influenced by several factors, among which the human factor plays the most prominent role. One of the most essential components of human agents is drivers. As a result, the quality of some parts of the traffic is variable based on their mental and spiritual characteristics. Among these aspects, aggressive driving has received more attention than other characteristics, so eva‎luation of some parameters like velocity has been of interest to researchers as factors that reflect aggression. This research firstly believes that the values of this kind of parameters are a necessary condition for occurring aggressive driving but are not a sufficient condition and secondly thinks that they are not able to interpret the whole aggressive behaviors. Based on this, knowing the examples of aggressive behaviors has been one of the upcoming requirements. To achieve that, a questionnaire was designed, and regardless of the statistical aspects of the answers, an initial assessment of those behaviors that threaten traffic conditions was obtained. Because of the high costs, potential risks, time-consuming, and unethical aspects of the field investigation of such behaviors, Using the simulation tools to assess the impacts of the mentioned behaviors on traffic is inevitable. Due to the nature of the research and its focus on drivers, the use of microscopic simulators is necessary. SUMO, because of its tools and advantages which will be discussed later, was chosen for this purpose. Then six inappropriate driving behaviors mentioned by the interviewees were simulated. At the end of examining each behavior, its impact on three factors including the number of cars entering the main street from the side street, the amount of carbon dioxide and noise produced, and the average speed in the network is eva‎luated. These factors are indicators of respect for the rights of other users, the quality of the air and the traffic environment, and the smooth movement of cars on the road, respectively. This research focusing on the driving behaviors in all of which selfishness is seen, believes that the solution to the traffic problems is on the other side of the coin in the concept of altruism or philanthropy from a bigger framework called adornment in traffic. Since adornment in traffic consists of three components, it is obvious that its full realization depends on the harmony of all elements consisting of law, wisdom, and altruism.
