سنجش ایمنی ترافیک در قطعات ترکیبی معبر و کاربری

Urban street design is closely interrelated with land use; each land use has its own trip attraction and generation. Any change in land use characteristics can alter travel patterns. Mixed-use land uses are considered important due to their high trip generation and attraction. In this paper, the CODAS model has been used to evaluate the traffic safety impacts of mixed-use land uses( its ability to provide double-check control of the results). By combining different functional classes and different land use groups, twenty mixed-use land uses in the city of Tehran were selected and examined. After categorizing the criteria related to land use and the street, the combined Shannon entropy and Best-Worst Method (BWM) was used to weight the criteria. According to the results, the highest weight in the land use section belongs to "building floor area" (0.324), and in the street section to "accident severity index" (0.226). Subsequently, street segments containing these land uses were ranked in terms of traffic safety using the hybrid CODAS model. This study is based on the combination of the considered land uses. According to the results, mixed-use land uses with construction group D located adjacent to the highway functional class have a higher safety risk, followed by group C adjacent to highway roads. The results of this research can be used for prioritizing and improving the safety of mixed-use land use areas, allocating safety budgets in the respective areas, and implementing the Code23 of the National Building Regulations regarding traffic requirements for buildings.
