(4) Producing Present OD Matrices (2010)<br />

(a) Present OD Matrices (2010)<br />

To produce present OD matrices, existing OD matrices are adjusted based <strong>on</strong> the traffic<br />

count survey.<br />

(b) Validati<strong>on</strong> of Present OD Matrices<br />

In order to c<strong>on</strong>firm the validity of the present OD matrices, these were assigned to the<br />

present road network and the assigned traffic volumes were then compared with the traffic count<br />

results. The results of comparis<strong>on</strong> are shown in Figure 3-7.<br />
