Figure 32: Downtown Pittsburgh VISSIM model for PM peak hour

To simulate a valid work-zone scenario, a segment of the 7th Street (from Fort Duquesne to Penn Ave) was closed and considered as a continuous work zone area. This segment was selected intentionally as it is one of the few segments in the center of the modeled network that give travelers a number of detours. The exact location of the work zone is shown in Figure 33 as the segment encircled with a red rectangle.
