INTERSECTION NODE DATA <br />Data entered for each node include the following: <br />Type <br />0 Node Capacity Factors <br />Capacity <br />• TMODEL Special Delay Links (SDLs) <br />• Base Delay <br />0 Turns <br />Node Type <br />The node classifications were coded in the model dependent upon the intersection <br />control. Table 4 lists the node types. These were modified from the previous model <br />structure to represent current practice. <br />Table 4 <br />Node (Intersection) Type <br />2008 Kittitas County Transportation Planning Model <br />Node Type <br />Description <br />1 <br />Not an Intersection <br />4 <br />Freeway Ramp Terminal — Merges <br />5 <br />Freeway Ramp Terminal — Diverges <br />10 <br />All -way Stop <br />11 <br />Partial.
