8 Amanda Spencer BASELINE REVENUE PROJECTIONS

9 Purpose Provides an estimate of revenues expected to be available for capital improvements to 2040 Identifies the funding gap between revenues and modal needs

10 Methodology Projection of baseline revenues by mode No new revenues Business as usual conservative estimate Based on current year revenues and short-term budgeted revenues, grown annually at assumed rates Converted to real dollars to account for inflation

11 Baseline Revenue Forecast Results Total Available : $27.04 Billion (in 2011 Dollars) SIB $2.04 8% State Transit $ % Federal Transit $1.01 4% SPLOST $ % C-Fund $0.85 3% State Highway $ % Federal Highway $ %

12 Total Available Revenue $1,800,000,000 $1,600,000,000 $1,400,000,000 $1,200,000,000 $1,000,000,000 $800,000,000 $600,000,000 $400,000,000 $200,000,000 $ Total Available Revenue (Nominal Dollars) Total Available Revenue (Real Dollars)

13 QUESTIONS

14 Don Vary Developing and Evaluating Modal Scenarios Status Update

15 Modal Scenarios Develop different allocations of longrange plan transportation revenue Revenue levels, investment types Evaluate according to quantitative and qualitative criteria Develop implementation strategies

16 Uses plan outputs Vision, goals, objectives Plan performance measures Needs, gap Baseline revenue forecast And creates new inputs Allocate fixed revenue levels into investment categories Measures of effectiveness Inputs

17 SCMTP Scenarios About $14.3B of $27.04B in available revenues is dedicated to current programs Remainder ($12.7B) treated as discretionary $30.00 Total Needs by Category ($billions) Program Dedications by Category ($billions) $30.00 $25.00 $25.00 $20.00 $15.00 $10.00 Preservation/ Modernization Capacity $20.00 $15.00 $10.00 Preservation/ Modernization Capacity $5.00 $5.00 $0.00 Interstate Other Federal-aid Local Passenger rail/bus Freight $0.00 Interstate Other Federal-aid Local Passenger rail/bus Freight

18 SCMTP Scenario Themes 1. Keep the Highway Core (Baseline) emphasis on primary (core) system Well maintained, congestion addressed, high access to key areas and within cities 2. Multi-modal Core System Maintain and expand highway, transit, rail and nonmotorized system linking cities and towns

19 SCMTP Scenario Themes 3. Serve the Drivers investments to spur business attraction and retention Ports, distribution facilities, airports, leisure destinations 4. Right Size System What size system will future revenue support?

20 Scenarios Themes Mobility & System Reliability Baseline - Keep the Core Serve the Drivers Multimodal Core System Right Size System Safety Infrastructure Condition Economic & Community Vitality Environmental Equity

Defined as the summation of the individual interstate mainline segment Densities for each of the four study hours for both directions. Average Density Index Performance Metric (Corridors) Corridors are made up of Multiple segments Developed to compare and rank the respective levels of congestion for the interstate corridors.

48 Project Costs Planning-level cost estimates were developed for the top 10 most congested interstate corridors. Based upon: Interstate Feasibility Studies that are currently underway or complete and SCDOT planning estimates. SCDOT Planning Office Estimates Planning-level cost of $15 million per two-way mile if no further information in known.

50 Environmental Screenings Establish the potential baseline of environmental impacts to cultural, natural, and social resources for Interstate segments. Considered: (1) wetlands, (2) streams, (3) threatened and endangered species, and (4) cultural resources. Each resource area received a score between 0 to 2, with 0 indicating low to no observations of the identified resources within the area of an Interstate segment and 2 indicating significant amount of observations.

64 Corridor Delay and Deficiencies Vehicle Hours Lost Performance Metric (Individual Segments) Developed to compare and rank the respective levels of congestion for the individual Strategic Corridor segments. Calculated from the actual average travel time versus the freeflow (uncongested) travel time from the INRIX data and AADT for both directions of each segment. Vehicle Hours Lost Index Performance Metric (Corridors) Developed to compare and rank the respective levels of congestion for the Strategic Corridors. Strategic Corridor segments were combined into larger corridors considering both uniform lengths and logical breaks. Defined as the weighted average of the segment Vehicle Hours Lost across all corridor segments.

65 MPO/COG Needs Data requested from MPO/COGs Unconstrained needs on Strategic Corridor Project information, termini and cost Majority of the needs US 123, US 17, US 25, US 78 and US 378 Waccamaw and Catawba COGs
