Although transit was not explicitly analyzed as a part of this study, a TSys for Bus was <br />also created for future use. <br />One-or Two-way Direction <br />All links were checked for one-or two-way entry. Interstate 90 and Interstate 82 were <br />coded as pairs of one-way links in VISUM. Typically, freeway s gments in modeling <br />are split into a pair of one-way links so that the difference in eapacitie and directional <br />splits can be modeled appropriately. On and off ramps fox the-s'e facili ties were also <br />coded as one-way links. <br />A one-way link is entered in VISUM by permit ting only the car and tr uck transp r ta tion <br />systems (TSys-Car and TSys-Truck) to m o~e in on e d irection and not the other. <br />Number of Lanes <br />This attribute is used in the VISUM m od -l r Wl to assign capacities to network links. It is <br />also used for display and for entering int~r ection geometry in VI UM. All model links <br />were checked for accuracy with this designa ti on . Nu01be r . f lan es per direction is <br />shown as Figure 4. <br />Kittitas County, Washington Transportation Model-May 2009 Page 13
