Influencing Factors of the Length of Lane-Changing Buffer Zone for Autonomous Driving Dedicated Lanes

With the development of intelligent transportation, dedicated highway lanes for autonomous vehicles (AVs), necessary ensuring their right way, have emerged as critical issues in transportation research, which makes it to set up specialized lane-changing buffer zones lane adjacent one. Restricted by current situation systems, based on NGSIM data, this study filters out typical description data featuring behaviors and constructs a principal component analysis (PCA) model containing factors affecting longitudinal driving distance during whole procedure. The validity is evaluated with significance test. Comparing PCA general linear regression model, suggestions setting length are put forward. zone mainly considers speed, acceleration, flow lane. In general, shorter can be achieved increasing design speed zone, raising headway AVs lane, reducing acceleration rate vehicles, time proportion change preparation stage, occurs earlier
