Comparison of GIS-based techniques in traffic accidents

Traffic accidents are one of the critical problems in our country as it is in the world. The World Health Organization case reports published in ۲۰۱۵ stated that approximately ۱.۲۵ million people die each year, and more than ۵۰ million people are injured due to traffic accidents in the world. In this context, many investments and studies have been performed to determine traffic accident black spots to reduce traffic accidents. Every year, several roads are restored or even built. Constructing these roads makes it simpler for people to travel and thereby minimizes the likelihood of accidents. Of course, this must be added that all of these freshly built highways have the potential for accidents, and all of these routes have sensitive places. As a result, by evaluating the eight accessible studies, this paper wants to examine the roads and the primary objective for their usage. Today it will discuss roads, accidents, sensitive and spectacular road spots, and the degree of road safety. In reality, this paper is a survey of all of these topics that are quite beneficial to everyone. This paper will also analyze and compare all of these concerns. Of course, it must be noted that even the most thorough and first-rate routes and highways have vulnerable spots where numerous accidents can occur. As a result, the difficulties and benefits of these areas by using GIS should be kept in mind.
