With the significant increase in population in urban areas and the continuous growth in the use of vehicles, traffic infrastructure is more in need of enhancement and revision than ever before to improve safety levels. In this regard, urban intersections, as one of the most sensitive and congested parts of the urban transportation network, play a crucial role in ensuring the safe and smooth movement of both vehicles and pedestrians. Due to the concentration of high traffic volumes, these points are more prone to conflicts, reduced safety levels, and the occurrence of risky traffic behaviors compared to other parts of the network. The increase in traffic volume in these areas can further create conditions conducive to accidents and unsafe situations. Therefore, identifying the factors influencing the safety of these intersections is essential for enhancing the quality of urban transportation services. In this study, data related to the geometric and traffic characteristics of seven signalized urban intersections were collected and analyzed. To obtain accurate information, aerial imaging techniques were used to record video footage at each of these intersections. The recorded images were then analyzed using image processing software. Additionally, the number of critical conflicts and post-encroachment time (PET) events at these intersections were calculated. A total of 20,412 events were considered for this traffic indicator. The results of statistical analysis, obtained using a multiple linear regression model, show that an increase of one unit in traffic volume can lead to a 1.6% increase in the number of critical conflicts. Furthermore, the analyses indicate that an increase of one meter in the average entrance width of intersections can increase the number of critical conflicts by approximately 11 to 16%.
