Thorough evaluation of suburban rail route alternatives is essential for determining the appropriate route. Suburban lines provide transportation services to suburban areas; that is, they provide transportation services to distant points of the city where demand is high. In this study, five alternative suburban rail routes in the commuter rail standard, starting from the Fatih Sultan Mehmet Bridge’s European exit and ending at Istanbul Airport, were determined as a sample corridor in the province of Istanbul. High-standard suburban rail routes and their infrastructure construction costs were determined, and route options were delineated according to their construction costs. Multi-criteria decision-making (MCDM) methods were examined, including the application of the decision matrix method (DMM) and analytical hierarchy process (AHP) to rank the routes in terms of the factors examined in the study. These routes were ranked according to the construction costs and according to the DMM and AHP methods, and the results were compared. In the decision matrix application, geomorphological-geological, geotechnical, infrastructural, and environmental factors were considered in the evaluation and determination process. A solution was developed in which all aspects were weighted to indicate their relevance, and these factors contributed to the determination of the results. The AHP method was also applied, in which five criteria were included in the evaluation: geology (including geomorphology and soil properties), engineering structures, construction costs, population values addressed by the routes, and railroad length. In addition, the distances to the active faults were examined according to the Turkey Earthquake Hazard Map specified in the Turkish Building Earthquake Code (TBDY) 2018. Depending on the factors studied, the ordering of the routes was the same for all three methods.

对郊区铁路路线替代方案的彻底评估对于确定合适的路线至关重要。郊区线提供前往郊区地区的交通服务；也就是说，它们为城市中需求量大的偏远地区提供交通服务。在这项研究中，通勤铁路标准中的 5 条替代郊区铁路路线，从法提赫苏丹穆罕默德大桥的欧洲出口开始，到伊斯坦布尔机场结束，被确定为伊斯坦布尔省的样本走廊。确定高标准城郊铁路线路及其基础设施建设成本，并根据建设成本划定线路选择。检查了多标准决策（MCDM）方法，包括应用决策矩阵法 (DMM) 和层次分析法 (AHP) 根据研究中检查的因素对路线进行排名。根据DMM和AHP方法，根据建设成本对这些线路进行排序，并对结果进行比较。在决策矩阵应用中，在评估和确定过程中考虑了地貌地质、岩土、基础设施和环境因素。开发了一种解决方案，其中对所有方面进行加权以表明其相关性，并且这些因素有助于结果的确定。还采用层次分析法，评价包括五个标准：地质（包括地貌和土壤性质）、工程结构、建设成本、路线所涉及的人口价值和铁路长度。此外，根据 2018 年土耳其建筑地震规范 (TBDY) 中规定的土耳其地震灾害地图，检查了到活动断层的距离。根据研究的因素，所有三种方法的路线顺序都是相同的。
