Planning considerations for underground train stations

The basic design considerations of an underground train station are tried to be defined and examined in this study. The issues covered are, basically, the circulation and spatial orientation, satisfaction of psychological and physiological comfort and safety issues. In the first stage of the study, data that can be used to improve underground train station environment was gathered. This data consisted of information on the major problems that the currently functioning systems are facing, various techniques and concepts developed to overcome these problems and evaluations on the effectiveness of such methods. With the help of the data and information gathered, a checklist on planning considerations for an underground train station was developed. The recently built Ankara Lightweight Public Transportation System's stations were observed and evaluated as a case-study, according to the issues raised in the checklist.
