Traffic Study Lexington Avenue Reconstruction Alliant No. 118-0186.0 25 April 18, 2019 3.4 Year 2040 No Build Traffic Operations Analysis A traffic operations analysis was conducted to evaluate the operational performance of the various intersections along the Lexington Avenue corridor under forecast year 2040 traffic volumes. The purpose of this no build analysis is to create a baseline to compare the performance of each potential build alternative; ultimately aiding in the selection of a preferred alternative to be evaluated in greater detail. In addition, the traffic operations analysis provides context to the need for intersection improvements based on intersection capacity. The key measures of effectiveness evaluated include overall intersection delay/LOS and worst approach delay/LOS. Table 7 provides a summary of the year 2040 no build traffic operations analysis for the Lexington Avenue corridor. Table 7. Year 2040 No Build Operations Analysis Summary Results of the traffic operations analysis indicate that the Lexington Avenue corridor intersections are expected to operate at overall LOS C or better under year 2040 a.m. peak hour traffic volumes. However, under year 2040 midday and p.m. peak hour traffic volumes, most study intersections are expected to perform significantly worse, enduring long delays and queues under no build conditions. It should be noted that these conditions are partly due to the analysis using existing signal timing. Updating the signal timing and coordination along Lexington Avenue may reduce the magnitude of these problems. Key conclusions of the 2040 no build traffic operations analysis include the following: x Red Fox Road: Issues noted previously under existing and year 2020 conditions are expected to be further exacerbated. During the forecast year 2040 p.m. peak hour, the Lexington Avenue / Red Fox Road intersection is expected to operate at overall LOS E. x Lexington Station: During the forecast year 2040 midday and p.m. peak hours, the Lexington Avenue / Lexington Station intersection is expected to operate at overall LOS F.
