IMAGINE 2040: HILLSBOROUGH LONG RANGE TRANSPORTATION PLAN Performance Measures Performance Measures are a key component of the Moving Ahead for Progress in the 21st Century Act (MAP-21). Congress established seven national goal areas in MAP-21: Safety – to achieve a reduction in traffic fatalities and injuries on all public roads. Infrastructure Condition – to maintain the public Chapter 3: Building the Plan highway infrastructure in a state of good repair. Congestion Reduction – to reduce congestion on Building something always starts from the ground up.

Reduced Project Delivery Delays –to reduce project costs and accelerate the completion of projects by eliminating delays in the project development and delivery process. 50 Chapter 3 Building the Plan IMAGINE 2040: HILLSBOROUGH LONG RANGE TRANSPORTATION PLAN Performance measures to achieve these goals are being established by US DOT, and each state will set its own targets Minimize Traffic for Drivers & Shippers against these measures. MPOs in Florida may adopt the Peak-hour travel time reliability statewide targets, and may create supplemental measures and targets appropriate for the metropolitan area. Affected truck trips For Imagine 2040, the Hillsborough MPO expanded on the MAP-21 performance measures and applied them to some of Real Choices When Not Driving the thorniest challenges facing the community.

Pavement preservation extends the pavement’s serviceable condition System preservation is a vital component to a long range over a period of time, improves safety, and meets transportation plan because investment for pavement motorists driving expectations. Preventive maintenance, preservation and new structural standards will be critical to minor rehabilitation, and routine maintenance are ensuring the viability of roads and bridges. Additionally, transit examples of common pavement preservation methods. system performance will not be jeopardized by fleet age and Hillsborough County has 12,025 lane miles and they are will be able to sustain for longer periods of time with maintained by the following agencies or jurisdictions: enhanced maintenance measures. Deferring preventative maintenance to fleet vehicles can lead to failure of the road base and lead to more costly roadway rehabilitation efforts. FDOT – 1,896 miles Measuring system preservation can be accomplished by the Hillsborough County – 6,920 miles maintenance schedule of roads and bridges, and transit fleet City of Tampa – 2,800 miles replacement schedule. Detailed information about system Temple Terrace – 165 miles preservation can be found in the System Preservation – Pavement, Bridges, and Transit Costs and Benefits technical Plant City – 150 miles memorandum. Tampa-Hillsborough Expressway Authority – 94 miles i. Pavement and Bridges Bridges are essential to the transportation network and Well maintained roadways and bridges are not only critical have an average life expectancy of 50 years. Current to Hillsborough County, but to the entire nation since spending on bridge maintenance in the county, as shown economic growth, national defense, and the movement of in the five-year work programs and capital improvement goods and people rely upon a well-maintained programs of Hillsborough County, the three cities, and infrastructure system. FDOT District 7, comes to an average of $31 million annually, or $620 million over 20 years. However, current From the 1960s through the 1980s, most Federal and funding does not adequately address all of the needs for State funding went to building new highways and bridges. 52 Chapter 3 Building the Plan IMAGINE 2040: HILLSBOROUGH LONG RANGE TRANSPORTATION PLAN major bridge repairs and/or replacements on some bridges every year, while in the medium investment scenario four for which Tampa and Hillsborough County are responsible. percent of roads are resurfaced annually.

Transit Fleet With the High Investment Scenario, the The latest data about transit fleet replacement was found in average vehicle age in HART’s fleet will be 5 HART’s fleet plan. The Federal Transit Agency’s (FTA’s) minimum vehicle life requirement is 12 years. Currently, years in 2040. HART’s fleet replacement plan indicates a funding shortfall to achieve the prescribed 12 year replacement schedule. The current funding level is illustrated in Investment Level 1, with Investment Statistics Total Level an average vehicle fleet age of 13 years in 2040, and an average of eight road-calls (vehicle breakdowns) each High Total capital required for fleet plan $168,086,862 weekday. The high investment level describes an optimum Average fleet age (2040) 5 years fleet maintenance scenario with an average of five road-calls Number of new vehicles 272 per weekday. The medium investment level, between these Road calls per year 1,316 two, was based on having an average fleet age of eight years Road calls each weekday 5 in 2040 with an average of six road-calls per weekday. Medium Total capital required for fleet plan $128,628,520 Average fleet age (2040) 8 years Figure 3-3 describes the high, medium, and low investment Number of new vehicles 246 levels respectively for each transit vehicle fleet replacement.
