Travel Time Reliability To measure travel time reliability, Travel Time Index (TTI) data was documented from Iteris Clearguide for 2019. The Travel Time Index 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 and evening TTI indicate travel times greater than 20% of the free-flow speed travel time in both directions for all study roadways except Sligh Avenue. Sligh Avenue has travel times greater than 10% in the westbound direction and typical travel times in the eastbound direction in the morning and evening. Trucking and Freight As defined in the Hillsborough TPO’s 2016 Freight Logistics Zone Strategic Plan, the 56th Street 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 the routes to be reliable from a travel time and pavement condition perspective. Truck routes are shown in Figure 9 with underlying p.m. peak-hour TTI, and in Figure 10 with the underlying pavement condition. Pavement condition is discussed further beginning on page 24. As noted in the Market Study for the redevelopment area, CSX representatives have determined several of the existing tracks and spurs in the area are not maintained or owned by CSX. The mix of CSX and private ownership limits the ability to improve rail connections that can ultimately improve the shipping activity in the area and region, an expressed interest by CSX. The tracks and spurs owned by CSX are shown in Figure 10 . Based on rail volumes from the Federal Railroad Administration, 1 train per week operates on the CSX track (Neve Spur) in the 56th Street Redevelopment Area. This spur has low utilization compared to the activity countywide which may be attributed to the termini within the redevelopment area and the close proximity to the Tampa Terminal rail yard. The CSX freight rail use has been reviewed by agencies throughout the region for potential passenger use for over 10 years. Although this segment of the CSX track would not be recommended for passenger use, it connects to other segments that may provide regional commuter rail potential.
