Introduction: One of the main weaknesses and problems in the field of road accident management is the lack or non-use of appropriate information systems. The overall aim of this study is to reduce the impact of road accidents in the west, southwest, and south routes of Tehran Province, Iran, by designing Management Database responsible for road accidents. METHODS: This was an applied study performed using the descriptive-analytical method in which the data entry and analysis were conducted in the Geographic Information System (GIS) environment in line with the objectives. Then, according to different requirements of the various users, an appropriate analysis was performed on the layers and the software spatial analysis was applied in line with the main objective of the study. In the next step, the desired outputs were extracted from the system and the main output, i.e. the comprehensive database of spatial data required to manage road accidents, was provided to the management levels of various organizations for planning. FINDINGS: In this study, the accident-prone areas in the studied routes were identified using the kernel density estimation (KDE) method. CONCLUSION: Performing various analyses on geographical and descriptive information and providing appropriate outputs and also sharing them can play an effective role in reducing injuries caused by road accidents.
