1.3. Proposed alternatives <br />During the kick -off meeting and 1St project meeting, the following alternatives were selected for <br />the further comprehensive review. <br />o Base scenario should include 1 -40 and 1 -85 widening projects since their funding <br />priorities / sources are more committed and different than other candidate projects in <br />the previous table. <br />o The Eno Mountain Rd. and Mayo St. alignment project (ID 8) is excluded since there is <br />no supply change. It is expected that short link length, lane configuration, or signal <br />phasing & timing change in TRM is not sensitive to the model output; however, the TRM <br />model is sensitive to capacity change on links. <br />o The Exchange Park Ln. connector project (ID 11) and Downtown TIP project (ID 12) are <br />removed from the alternative list for an apple to apple comparison. The projects can be <br />reviewed using other traffic operational analysis tools (i.e. TransModeler) if additional <br />analysis time and data are available. <br />0 10 scenarios including base scenario will be analyzed. The scenarios are shown in the <br />figures below. In the figure, each color and line has a different meaning; <br />■ Red color with solid line: a widening project, <br />■ Red color with dotted line: new project, <br />■ Green color with dotted line: Advanced Traveler Information System or signage <br />with small improvement project, and <br />■ Purple color: bus route. <br />28 <br />
