According to one embodiment, a system determines a first trajectory (e.g., a reference line) based on map and route information of the ADV. The system determines a maximum curvature for a predetermined distance for the first trajectory. The system determines a sampling decay ratio based on the maximum curvature. The system generates one or more sets of sample points for the first trajectory, where each set of sample points include one or more sample points separated by a lateral distance apart based on the sampling decay ratio. The system generates a second trajectory for the ADV based on the sets of sample points to control the ADV, where the second trajectory nudges to a left or a right of the first trajectory based on the maximum curvature of the first trajectory.
