 A new microscopic traffic model was developed which characterized driver response as either reactive, sensitive, or typical. This model was found to be more accurate than the existing intelligent driver model, which uses a fixed acceleration exponent. The proposed model was tested on a circular road of 1,200 meters with a platoon of 21 vehicles for 150 seconds. Results showed that the proposed model accurately represented real-world traffic behavior, while the intelligent driver model did not.
