Analysis of Boundary Condition Model under Cut-in Scenarios Based on Logistical Regression Method 2019-01-5047

Analysis of driver brake behavior parameters of cut-in scenarios is conducted based on naturalistic driving data and accident collision data. The characters of different critical level cut-in cases (normal case, conflict case and collision case) can be obtained by the Time headway (THW) and relative velocity parameter when driver brake initiation. The representative cases, which are selected according to the risk evaluation method, are chosen to evaluate driver’s timing of brake initiation. Using logistical regression method, the cut-in boundary condition model is established with THW and relative velocity parameters. Based on the China Field Operation Test database and China in Depth Accident Study database, the comfortable and safety boundary conditions of cut-in scenarios are established, which is used to optimization the longitudinal control systems of Chinese intelligent connected vehicles.
