Today, due to the increase in the share of rail transport in the daily movement of people, reliability plays an essential role in the choice of the travel method of passengers and directly affects the level of passenger services, and also reliability is an important indicator for eva‎luating the quality of system services. Rail transport. Travel time plays an important role in the decision-making of travelers, and travelers are looking for trips that, in addition to having less travel time, also have maximum travel time reliability, therefore, travel time is the most important limitation of a transportation system, and since the system The transporters failed to fulfill their duties, the fact of arriving on time gained great importance over time. In metro systems, where passengers pay more attention to the reliability of travel time compared to out-of-town trips, it shows the importance of the maximum reliability of travel time in intra-city rail trips. Travel time reliability is an important feature for choosing the type of travel, for this reason, travel time reliability is one of the most important indicators for eva‎luating the quality of rail transportation system services. Therefore, reliability is the most important performance indicator of a time-dependent system and has a significant impact on its economic benefits. This study consists of three stages. In the first stage, the collection of AFC data and the description of the basic structure of the data and the actions taken to prepare the data are discussed. The data used for Tehran subway is in May 2017. In the second step, the reliability of the travel time is calculated, which includes two buffer time index and the planning time index. The main criterion in this study to eva‎luate which of the routes have high reliability is the time index. is a barrier in the third stage, the routes are clustered based on the K-Means method, and the appropriate number of clusters is obtained based on the silhouette criterion.
