A Study on Parameters Affecting the Track Quality of High Speed Rail Tracks
Öz
Railway track maintenance and renewal activities are performed depending on the changes in track quality. Track quality indicates the operating condition of the track and the quality is usually expressed with a numerical index. Known as track geometry indexes, these indicator values are calculated based on data obtained from the track geometry control measurements. In this study, using the data obtained from the Ankara-Eskisehir High-Speed Rail (HSR) track, the factors affecting the track quality of HSR track were determined. For this purpose, firstly the track under investigation was divided into analysis segments considering the rail alignment geometry. Then, by analyzing the data of the track record car measurements, the degree of deterioration occured in the analysis segments and the change of track quality were examined in the segments where deteriorations occured. At the end of the study, multivariate regression models were constructed in order to determine the factors affecting the track quality. According to these models, it was determined that the factors affecting the track quality are traffic-related parameters, type of analysis segment and previous value of track quality.
