To draw a route, select the nodes and links to form the route, then identify the route start and route end, and identify the route segments and/or sections. As described above, setting segments and section ends is optional; however, the user may wish to do so to establish where level of service analysis will be calculated and to account for signalized intersections without signal timing data.
Selection is done by pointing to the desired item and using the Shift-LeftClick keystroke, or by using the Shift-LeftClick-Drag combination to surround one or more items with the marquee box. The item will change color to indicate that it has been selected. Unselect items using Shift-LeftClick keystroke again, or by using Ctrl-LeftClick-Drag combination to again surround one or more items with the marquee box.
Specify the route start by placing the cursor over the start intersection and using Ctrl-Shift-RightClick. This keystroke sequence is used to specify four route markers. The first click indicates the route start. The second click is the route end. The third click is a route segment, and the fourth click is a route section. You can confirm that you are specifying the correct item by watching the item selection line below the lower left corner of the network window. The intersection icon will also change color with each click. No color means the intersection has not been identified with any of the four items.
The keystroke technique described above for specifying route markers works at all nodes, including cross-street nodes. At intersection nodes, the route markers can also be set by pointing to the intersection and using RightClick. This brings up the intersection pop-up menu, which includes the Route Marker option. Choose the desired route marker from this menu.
Start the route at the node that is just upstream of the first intersection to be included in the route. The delay at the starting node is excluded from the total travel time computation and the first link will not actually be part of
the route; it is only used for establishing the turning movements for entering/leaving the route. (Similarly, end the route one node downstream of the last intersection to be included in the route.)
