Accidents vehicles and pedestrians are the result of an increase in vehicles, and the lack of any planning will cause irreparable damages. Such planning requires prediction models that determine the effect factors and prioritizations possible. Imam Khomeini Street, which is a two-story street in Esfahan, Iran, is ranked first in accidents. Therefore, the aim is to analyze different solutions and their combination and prioritize them for reducing and preventing accidents by modeling.

The crash statistics of 2015 were used. Details were collected through field studies, and the definition of strategies and modeling were done in the IHSDM software. Due to ethical considerations, the people’s identity was not provided by the police. Solutions for removing the marginal park, reducing access, increasing distance, and reducing the fixed objects and their combination were analyzed. For Bridge, the increase in the number and width of the passageways and the distance between barriers were investigated.

The need to calibrate the IHSDM software became clear, and the analyses showed that if no strategy was implemented, the crashes would increase by 12.6%. Among the individual and combined solutions, the removal of the marginal park and the use of four solutions at the same time, and for the bridge, the increase in the distance barrier were identified as the most influential.

It became clear that the application of models, the provision of solutions, the study of the effect and the prioritization and using all factors involved in crashes is necessary
