sets. Generally, the results show that individual projects included in all of the alternatives provide a benefit in some way, without causing a corresponding detriment on another roadway. In all alternatives during the AM peak period, Bloomingdale Avenue continues to be over congested in the westbound direction, but is not expected to get significantly worse or better under any alternative. Results for the recommended alternative are discussed in Section 5.
Similar to the analysis completed for the E+C Model, the volume to capacity (V/C) ratio was calculated for the AM and PM peak periods for E+C+LP Widening and each alternative. Results are shown in Figures 27 to 44. Table 4 provides a summary of the findings for each of the alternative

E+C+LP
Addresses congestion on Lithia Pinecrest Road by providing additional capacity.
Additional capacity on Lithia Pinecrest Road draws more traffic away from Fishhawk Boulevard and Bell Shoals Road, reducing congestion on these roadways. The widening also reduces congestion on Lithia Pinecrest Road, but pushes more traffic onto Lumsden Road and SR 60, causing these facilities to worsen. In the AM peak period, traffic is routed away from Lithia Pinecrest Road to Bell Shoals Road, due to the new connection to Lumsden Road. This reduces congestion on Lithia Pinecrest Road, but worsens conditions on Bell Shoals Road. Lumsden Road also sees an improvement due to the widening. In the PM peak period, the Lumsden Road widening continues to provide a benefit on this roadway, but the improved connection between Lumsden Road and Bell Shoals Road is not as pronounced; Lithia Pinecrest Road continues to be heavily congested in the PM. Vehicles utilize the new Brandon Parkway extension in both the AM and PM peak periods, however, there is not a substantial shift in traffic to this new roadway away from Lithia Pinecrest Road to make a significantly noticeable overall benefit to the network. In the both the AM and PM peak periods, Lithia Pinecrest Road sees mild congestion relief north of Bloomingdale Avenue, while Lumsden Road sees congestion reduction. Lithia Pinecrest Road south of Bloomingdale Avenue, along with other major roadways in the network see virtually no change in operations. In both the AM and PM peak periods, vehicles are rerouted to Bloomingdale Avenue from Lithia Pinecrest Road to reach John Moore Road and ultimately the widened portion of Lumsden Road. This rerouting results in some congestion relief on Lithia Pinecrest Road, without significantly impacting Bloomingdale Avenue.
Alternative Set 1
Addresses congestion on Lithia Pinecrest Road by providing an alternative connection to Lumsden Road, while addressing the congestion on Lumsden Road and Fishhawk Boulevard.
Alternative Set 2
Provides an additional north-south roadway connection to Brandon Parkway and a new east-west connection between Kings Avenue and Providence Road. Also addresses congestion on Fishhawk Boulevard. Addresses congestion on Lumsden Road and Fishhawk Boulevard with the use of full corridor widening. Lithia Pinecrest Road congestion is addressed through the use of intermittent widening. Addresses Fishhawk Boulevard with full widening and Lumsden Road with partial widening. Lithia Pinecrest Road congestion is addressed through the use of intermittent widening.
