Lane Change Behavior Research Based on NGSIM Vehicle Trajectory Data

This paper adopts the database from Next Generation Simulation (NGSIM) collected by National Highway Traffic Safety Administration, and analyzes the lane change behavior of vehicles comprehensively. Based on NGSIM data set, the internal relationship between data and lane change behavior is researched in depth, and the preprocessing method of original data is proposed, including data cleaning, feature adding and data initialization. Finally, according to the characteristics of the decision stage and the execution stage of the lane change, the data after preprocessing are processed further, including data extraction, feature selection, label making and so on. The data processed in this paper can be applied to the subsequent research.
