ABSTRACT

Track Inspection Car has been an effective automation tool to measure track geometric status in urban rail transit, and the accuracy of mileage affects directly the analysis of the location and its counter-measurement of track irregularity. In Shanghai Metro, the mileage of curves inspected by track inspection car is found to be different from the actual mileage recorded in document. In order to explore the reasons and change rules of such error, some analysis is carried out in this paper, and an automatic calibration model and its calculation method are put forward. Large amount of data analysis result shows that the method is correct, reliable and useful.
