Abstract

Abstract

Urban accidents are one of the major causes of death and injuries in metropolitan areas. As urbanization continues to accelerate, with more people moving to cities seeking better opportunities and a higher standard of living, the risks associated with urban accidents become more apparent. Investigating the reasons behind this issue and proposing effective solutions is a concern for policymakers. In some cases, the driver is responsible for accidents, while in others, the built environment contributes to the accidents. The aim of this article is to examine factors related to built-environment conditions. Overall, the parameters are divided into four categories: accident, demographic, traffic, and roadway. Relationships between each factor and the occurrence of accidents (in terms of fatalities, injuries, and damages) are examined. The factors in this report focus on external factors related to vehicle activities are the focus of this report. This study focuses on the causes of urban accidents in Tehran, based on aggregate data from 2000 to 2020 in each region. It is concluded that the main causes of this issue include the high number of motorcycles in the city center, excessive speed on congested roads, high vehicle density in certain parts of the city, and unsafe roadways. Effective measures include road repair and renovation, urban development, the implementation of speed limits on highways, the imposition of restrictions on motorcycles on high-speed roads, implementing demand management strategies to reduce traffic on congested roads, establishing feasible options for motorcycle riders, and rigorously enforcing traffic regulations.
