This report presents the continuation of the development of a naturalistic driver model (PADRIC) initiated under MOU 369 Human driver model. The development consists of increasing the scope of simulation capabilities to lane-change maneuvers and gathering data for the calibration of the car-following mode already implemented. The first part of the report presents the development of the model architecture for integrating lane change maneuver. The second part is focused on the data collection that was conducted and proposes a discussion of the method and shortcoming for gathering the data of interest.
