Dear Editor.

Please heip us correct a word in our paper.

The details are as follows:

Journal: PLoS ONE

Full citation of the article: https://doi.org/10.1371/J...

Description of the error: In the last line of section 2.3.5, the sentence "where cij is the distance from i to j" needs to be changed to "where cij is the travel time from i to j". In short, in this sentence, the word "distance" needs to be changed to "travel time". Thank you very much.

Best regards,
