2. Presentation Outline What is DCHC MPO? What is 2040 MTP? What is Alternatives Analysis? How to understand the data provided for the Alternatives Analysis Next steps
3. What is the DCHC MPO? Durham-Chapel Hill Carrboro Metropolitan Planning Organization Responsible for long range transportation planning in Durham City and County, and Parts of Orange County and Chatham County. Federal mandate – MPO must plan use of federal transportation funding Project must be in MPO plan to receive state or federal funding (CTP, MTP and TIP) Policy Board -- Transportation Advisory Committee (TAC) composed mostly of local elected officials.
4. What is the DCHC MPO?
5. Relationship Between Plans Comprehensive Transportation Plan (30+ Year Needs) Metropolitan Transportation Plan (Minimum 20 Year Plan) Collector Street Plan TIP (7 Year Plan)
6. What is the 2040 Metropolitan Transportation Plan (MTP)? Lists highway, transit and other transportation projects to address future transportation deficiencies through year 2040. Assumptions – based on future land use, population and employment. Fiscal Constraint – Anticipated revenues must cover anticipated project costs. Funding -- Projects must be in MTP to receive state and federal funding (via Transportation Improvement Program – TIP) Used for Planning e.g., In development review, use MTP to reserve right-of-way for future highway and fixed guideway projects
7. What is the 2040 MTP Process? By June 2013 8. Federal Approval 7. Air Quality Conformity Jan.-Apr. 2013 6. Draft MTP Dec. 2012 5. Preferred Option Oct.-Dec. 2012 4. Alternatives Analysis Aug.-Oct. 2012 We are Here! 3. Deficiency Analysis 2. Socioeconomic Data (population and employment forecasts) 1. Goals and Objectives
8. Alternatives Analysis What – Set of highway and transit projects, and land use assumptions that produce transportation scenario for year 2040 Why – Compare impact of different projects and sets of projects on meeting transportation demand. Inform development of final MTP and CTP When – Release in August 2012 Public input (e.g., workshops, public hearing) in August, September and early October 2012
9. Alternatives Analysis (cont.) We will compare 5 different Alternatives Each Alternative had the following: Land Use Scenario Transportation Network Alternative
10. Alternatives Analysis -- Land Use Scenarios We start with Guide Totals Population Employment
11. Alternatives Analysis -- Land Use Scenarios Community Plan Based on local comprehensive plans Used in Deficiency Analysis (June 2012) All-in-Transit Based on local comprehensive plans, plus… Additional and enhanced transit oriented development Additional development attraction to rail and premium transit
12. Alternatives Analysis -- Land Use Scenarios Orange County Dwelling Units Community Plan All-in-Transit
13. Alternatives Analysis -- Land Use Scenarios Orange County Employment Community Plan All-in-Transit
14. Alternatives Analysis -- Transportation Networks
15. Alternatives Analysis -- Transit Intensive Highways Only highest priority highway projects 2015 and 2025 tiers from 2035 LRTP East End Conn. I-40 and I-85 in Orange Co. US 70 and I-85 in Durham Co. NC 54 in Durham Co. 120 new lane miles $1.2 billion est. highway cost
16. Alternatives Analysis -- Moderate Highways Basically 2035 LRTP Plus.. I-40 HOV/HOT Northern Durham Parkway US 15-501 Freeway Conversion NC 147 widening NC 54/US 15-501 Bypass (Chapel Hill) 261 new lane miles $2.5 billion est. highway cost
17. Alternatives Analysis -- Highway Intensive Highways Basically 2035 LRTP Plus CTP highway projects Plus.. I-40 (ext.), I-85 and NC 147 HOV/HOT US 15-501/Manning interchange NC 751 in Chatham Co. US 70 bypass widening (H’boro) 410 new lane miles $3.9 billion est. highway cost
18. Alternatives Analysis -- Highway Intensive Transit Current bus transit No rail transit
19. Alternatives Analysis -- Moderate Transit Plus… bus transit in county plans LRT and regional rail based on LPA MLK Blvd bus rapid transit (Chapel Hill)
20. Alternatives Analysis -- Transit Intensive Transit Plus… LRT Durham to Raleigh LRT and CRT extensions in Orange Co. CRT: Cary through western RTP Addt’/ bus rapid transit in Chapel Hill
21. Alternatives Analysis -- Triangle Regional Model Output Triangle Regional Model Output Performance Measures Travel Isochrones Travel Time Congestion Maps (V/C) Currently running the two Transit Intensive Alternatives, again. Results available early next week.
22. Alternatives Analysis -- Performance Measures (VMT & Peak Speed)
23. Alternatives Analysis -- Performance Measures (Mode Share)
24. Alternatives Analysis -- Moderate Network (boarding/alighting by stop) All-in-Transit land use scenario provides about 25% increase in rail boardings/alightings.
25. Alternatives Analysis -- Transit Intensive (boarding/alighting by stop) Station boarding/alighting is generally low west and north of UNC campus (above red line in table) Caveat – The Transit Intensive network must be run again to correct highway network. These values could change.
26. Alternatives Analysis Output – Travel Times
27. Alternatives Analysis Output – Travel Times
28. Alternatives Analysis Output – Travel Times
29. Alternatives Analysis Output -- Congestion Maps - Moderate In Moderate, clears up congestion on many major roads, but congestion persists on I-40, NC 147, NC 54 and US 15-501.
30. Alternatives Analysis Output -- Congestion Maps – Highway Intensive In Highway Intensive, congestion persists on many of the same corridors.
31. Alternatives Analysis Output -- Congestion Maps – Transit Intensive In Transit Intensive, congestion (still) persists on many of the same corridors.
32. What are your preferences? Given the limited budget, and projected areas of congestion, where do we invest our money? Are there certain projects and policies that should be promoted? Invest more on Roadways or Transit? Invest more on roadway widenings or “hotspots” (e.g., intersections with long delays)? Invest more on local bus service or fixed guideway service (e.g., rail transit)? Use traditional revenue sources only or increase local taxes (e.g., sales tax, real estate transfer tax)?
33. 2040 MTP -- Next Steps Develop the Preferred Option (release in October 2012) Get public feedback on the Preferred Option (October through December 2012) Approve draft 2040 MTP (December 2012)
