Corrections: Optimal trajectory planning of connected and automated vehicles at on-ramp merging area (IEEE Transactions on Intelligent Transportation Systems (2021) DOI: 10.1109/TITS.2021.3116666)

In the above article [1], Fig. 9 should appear as: (Figure presented). Also, on the same page, bottom left column, the sentence: "Fig. 9 illustrates that the TET of the proposed controller is always larger than the baseline scheme under various initial speeds of the merging vehicle. The results demonstrate that the proposed controller has a significant improvement in reducing disturbances in the platoon."
