The Method of Train Positioning Based on Digital Track Map Matching

摘要：

　　A train positioning method based on GPS and digital rail line matching is proposed.Firstly,the digital track line is generated based on the fitting and interpolation algorithm of train track line.And then the GPS data are corrected by the track line positioning correction method,and the more accurate position estimation of the train is obtained.Finally,the data track line is simulated and analyzed with some measured data from Harbin to Qigihar track line.The analysis results show that cubic spline curve is better than cubic B-spline curve on the establishment of digital track map.
