Reviewer 13 of ITSC 2022 submission 839 Comments to the author ====================== This study proposed GAPFORMER which combines the Transformer and RNN architectures to better model and personalize driver trajectory. In my view, there are a few problems the authors should address. The specific comments are provided as follows: 1. The first time the “MSE” and “SGD” appears in the manuscript in P4, they should be marked with full name. 2. The font in the figures should be enlarged to make the information clearer, such as in Figures 4, 5, 6.

The content of the abstract is all about the contribution of this study and lacks a description of the research method. The abstract should be improved.
