Problems solved by technology

[0006] 1. The detailed information of the trajectory data is missing, and some important attributes are hidden
[0007] 2. Did not use historical real data
Unable to reflect real traffic characteristics
[0008] 3. The trajectory pattern generated by the existing technology is single, only considering the driving situation of a single vehicle, and does not consider the overall characteristics of the trajectory data of multiple vehicles
[0009] 4. Using the method of feature engineering to extract the features contained in the data is time-consuming and laborious, and there are many subjective factors, which cannot fully reflect the features contained in the data

Abstract

The present invention proposes a method for generating a vehicle trajectory, comprising step 1, a data processing stage, wherein the data processing stage is to preprocess trajectory data and map data; step 2, a data generation model stage, and the data generation model stage includes Generate a road section trajectory generation model and a travel trajectory generation model; Step 3, the data set generation stage, the data set generation stage is to load the road section trajectory generation model and the travel trajectory generation model to obtain trajectory data.

Description

technical field [0001] The invention relates to a trajectory generation method, in particular to a vehicle trajectory generation method. Background technique [0002] With the rapid development of Internet technology and the technological progress of the Internet of Things, people's living standards have improved, and at the same time, they have a new definition of quality life. Quality life must not only satisfy comfort and convenience, but also be intelligent and scientific. From the initial Internet to the Internet of Things in full swing, people's lives have undergone more and more incredible but real changes. The Internet of Vehicles is a typical application scenario of the Internet of Things technology in realizing intelligent transportation, and the goal is to build an intelligent transportation network. The main concerns of the Internet of Vehicles include data acquisition, data computing and processing in the cloud, offline data mining, and the development and imp...
