A system adjusts a vehicle speed prior to a lane change for an autonomous driving vehicle (ADV). The system: plans a hypothetical rough path without lane change; determines virtual non-blocking Station-Time (ST) boundaries of potentially interfering vehicles in a target lane, comprising shifting the hypothetical rough path to an ST coordinate system associated with the target lane; determines projected ST boundaries, comprising projecting the virtual non-blocking ST boundaries onto a real ST coordinate system associated with a current lane; determines residual ST boundaries, comprising keeping only part of the projected ST boundaries where t>t0, wherein t0 is a parameter; and performs speed optimization based on the residual ST boundaries.
