3.3 Existing Network Performance The initial Aimsun model was developed using the existing roadway network along with funded or committed projects. The funded or committed projects that were included are shown in Table 1 and Figure 15. The performance results of the E+C Model were analyzed to illustrate how vehicles move through the network and isolate congestions hot spots by peak travel period. An existing volume to capacity (V/C) ratio was calculated for each of the major roadways within the study area in the AM and PM peak periods (see Figures 16 and 17).
The E+C Model results show that motorists have different travel patterns and use different roadways in the AM and PM peak periods as they travel between home, work, and other destinations. Also, recent growth in the Fishhawk area and the Bell Shoals Road widening project, will result in some roadways, including Fishhawk Boulevard, having higher levels of congestion. Additionally, the existing network relies on three major east- west corridors, which experience heavy congestion from local traffic as well as regional traffic through the study area. The study area does not have a well-developed secondary roadway network to help support these major east-west corridors.

Extend the northbound right (NBR) lane and convert to a shared northbound through right (NBTR) lane. Widen to allow for two WBT lanes. Widen the NB I-75 On Ramp from NB US 301 from 1 lane to 2 lanes. Intersection improvements at SR 60/Lakewood Drive, SR 60/Kings Drive, and SR 60/Parsons Boulevard. Extend turn bays and convert unsignalized intersections to signalized intersections. Intersection geometry reconfiguration involving Durant Road and Bell Shoals Road. Entrance to the NB I-75 Loop On Ramp moved to connect with the SB I-75/ Frontage Road On Ramp.
