#### 2.1.2 Debate on the Directions of Development in Road and Pedestrian Safety  
From studies and research conducted to eliminate or significantly reduce the number of road accidents, it is important to address issues regarding pedestrian intentions and the predictability of movements performed by them. The emotional states of drivers that condition or impose certain barriers and produce behavioral reactions are often responses conditioned by what the driver is going through, subsequently requiring the analysis and detection of preventive behavior and the use of seat belts. According to studies, the factors presented above are the basis of many road accidents or adverse events in traffic. Thus, we can say that uncontrolled reactions or unpredictable movements of drivers or pedestrians in a fraction of a second can produce an unfortunate event that can lead to loss of life. In the first phase, we can say that a large part of reaction and driving style is directly influenced by the emotional states that a driver or pedestrian goes through, thus changing the degree of concern, related activities, attention, confusion, nervousness, and other factors that manage to distract them and making them vulnerable. According to the medical literature and analysis performed by Dr. [PERSON], emotions have a role and behavior is directly influenced by them. This study was performed using magnetic resonance imaging (MRI) observing in detail brain activity and emotion produced by states, feelings, deeds, and reactions [30; 31].  
Therefore, emotions force human beings to act and decide in a timely manner, especially if we exemplify this through a case study of angry people who in a state of reflex just want to get out of that area or to 'face the opponent'. Such reactions are also provoked in the case of happy or unhappy drivers; others result and emanate positive states that make them focus only in that direction and others do the opposite, but the conclusion is that both states cause altered movements and lead to inconsistency whether in driving or walking.  
We can say that the role played by emotions and other mental states, including fatigue while driving a car, is essential. These become extremely important factors in influencing decisions affecting types of reaction, perception and organization of memory [32; 33], details, classification, preferences, evaluation, decisional analysis [34; 35], concentration, attention, performance, and communication [36; 37]. The efforts made by academia and research teams, including the development of intelligent systems to analyze the human factor, have progressed in a certain direction, but insufficiently in terms of the number of road accidents. The analysis of the driver with each use of the vehicle is not enough because conditions can change quite often and unpredictably. A driver's emotional state must be uniform and support his/her abilities without disturbing certain activities. Thus, we consider extremely important the direction of research developed by exposing the problems in practical cases and solving them with the help of systems dedicated to traffic safety and pedestrian safety. These developed and developing components are meant to analyze and process all the necessary information from the external environment and to transmit it to drivers, vehicles, pedestrians, but also to intelligent traffic systems, all within a hybrid-mixed platform to reduce the problems previously mentioned.
