Abstract: Finding the shortest path is one of the important steps to optimize the transportation system. In order to find the shortest path, a dynamic programming algorithm based on ARIMA model and K-means clustering analysis was established by using historical and real-time floating-car data. The algorithm was tested in the second ring road area of Chengdu using Didi travel data. The results show that the newly proposed algorithm provides high-quality time solutions with low computation. The operation time is less than 2.010 minutes, the mean absolute percentage error is less than 6.5% and the invalid value ratio is less than 20%.

Key words: traffic engineering; dynamic programming algorithm; K-means clustering analysis; ARIMA model; the shortest path
