Linear regression analysis of the ridership and accessibility models. Actual population \(m_{\tau }^{(\mathrm{{a})}}\) versus predicted population \(m_{\tau }^{(\mathrm{{p})}}\) from the ridership model is plotted for (a) the daytime (\(\tau =1\)) and (b) the evening (\(\tau =2\)). In (c) and (d), actual population versus predicted population from the exponential accessibility is presented for the daytime and the evening, respectively. The coefficient of determination takes the values \(R^{2} = 0.29, 0.38, 0.32, \text{and }0.27\), respectively
