Embodiment Construction
[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0054] see figure 1 , the present invention comprises the following steps:
[0055] Step 1: Data collection and data preprocessing
[0056] First of all, for the calculation of the algorithm and subsequent experiments, the experimental data collected is the 11,000 taxi trajectory data from February 24, 2016 to March 31, 2016 in Xi'an City as the original trajectory data set. The data of these collected original trajectory data sets cannot be directly used for calculation. Due to the existence of some abnormal points and repeated points in the original trajectory data set, it is necessary to delete or delete the abnormal data such as abnormal points and repeated points in the original trajectory data set It can only be used after preprocessing such as correction, and the data in the original trajectory dataset is processed to obtain the prep...
