The distribution of Pearson correlation coefficient of \(\pmb{q_{c}^{r} }\) and \(\pmb{\mathrm{CDI}^{r}}\) . (a) The distribution of Pearson correlation coefficient of \(q_{c}^{{r}}\) and \(\mathrm{CDI}^{r}\) for the whole day. (b) The distribution of Pearson correlation coefficient of \(q_{c}^{{r}} \) and \(\mathrm{CDI}^{r}\) during morning peak. (a) contains indices of all days in October, while (b) only involves indices in workdays in October.
