Transportation Assessment The Palm River Redevelopment Area is generally bounded by state-owned principal and major arterial roadways including US 41, US 301, I-75, Selmon Expressway and Causeway Boulevard (FL 676). Access from I-75 to the study area is limited to only US 301 and Causeway Boulevard. Falkenburg Road and Madison Avenue/Progress Boulevard are also classified as arterial roadways, but are maintained by Hillsborough County with Suburban context classification and provide connection to residences and employment areas internal to the area. 36th Street, Hartford Street, and 78th Street are defined as collector roadways, maintained by Hillsborough County and have Suburban or Urban context classification to provide user facilities for higher non-vehicle activity. The roadway classifications and characteristics are described further in the following Transportation Assessment. Congestion Management Roadway Level of Service Peak volume to capacity (v/c) data from the 2019 Level of Service (LOS) Report was reviewed as the most recently available data due to COVID-19 impacts to traffic conditions. Capacity is based on the adopted LOS for each roadway. A v/c ratio of 1.00 or greater indicates that the volume exceeds the capacity of the road and indicates areas with a high amount of peak congestion. The roadway v/c ratios and average daily traffic are To measure travel time reliability, Travel Time Index (TTI) data was documented from Iteris Clearguide for 2019. TTI is the ratio of the travel time during the peak period to the time required to make the same trip at free-flow speeds. The TTI was documented for the a.m. peak-hour period (7 a.m. to 9 a.m.) and the p.m. peak-hour period (4 p.m. to 6 p.m.). The morning TTI indicates travel times greater than 20% of the free-flow speed travel time in both directions for all study roadways except for US 41 and S 78th Street. Both US 41 and S 78th Street have travel times greater than 10% in the southbound direction. The evening TTI indicates travel times greater than 20% of the free-flow speed travel time in both directions for all study roadways except for S 78th Street and I-75. Both roadways have travel times greater than 10% of free-flow speed travel time in both directions. Trucking and Freight shown in Table 5 and Figure 6 . Travel Time Reliability As defined in the Hillsborough TPO’s 2016 Freight Logistics Zone Strategic Plan, the Palm River Redevelopment Area is within a logistics cluster as an existing center of freight activity. As a result of the industrial uses and freight-oriented businesses, several truck routes and rail lines connect into the redevelopment area. To best serve those uses, it is important for truck routes to be reliable from a travel time and pavement condition perspective. Truck routes are shown in Figure 9 with the underlying p.m. peak-hour TTI, and in Figure 10 with the underlying pavement conditions.
