1 Let s Make I-40 Better Action Team Friday, March 29, 2019 Hosted by RTP Foundation

2 RTA Welcome Geoff Lang, MetLife, RTA Chair Jim Beley, The Umstead Hotel & Spa, RTA regional travel experience chair

3 NCDOT Welcome Meredith McDiarmid, NCDOT I-40 Regional Partnership Executive

4 Host Welcome Tim Brock Research Triangle Foundation

5 Action Team Objectives Joe Milazzo II, RTA

6 Action Team and Meeting Objectives Understand current and expected operation and planned projects for I-40 and vicinity Generate ideas for: accelerating or improving existing plans advancing a smaller piece of a proposed project new low-cost improvements Identify action we can take to implement or explore at least one new approach

7 Current and Expected Status of I-40 Dr. Joe Hummer NCDOT Mobility & Safety

8 Current and Expected I-40 Status Joe Hummer, PhD, PE State Traffic Management Engineer For RTA I-40 Action Team, March 29, 2019

9 Particularly Between NC-147 and I-540 It s important It s bad How bad is it? It s going to get worse How much worse? Constraints Opportunities

10 NC s Main Street Besides NC-147, the only freeway connection between I-85 and I-95 in NC

11 Geometry 4 lanes, lanes plus aux., lanes plus aux., lanes plus aux., 2500

12 Left entrance at NC-147 Interchanges Otherwise ¾-cloverleaf is OK Parclo ABs at Davis, Miami, and Page Not terrible designs Weaknesses include lane utilization, unusual maneuvers, and poor signal progression They are working pretty well

14 Travel Time, 7:40 AM From Google, typical traffic

15 Travel Time, 3:35 PM

16 Travel Time, 4:25 PM

17 Travel Time, 5:30 PM

18 HERE probe data NC-55 to Airport Boulevard Travel Time January and February 2019 Tuesday-Thursday Direction Free-flow travel time, min Average speed, mph 5-6 pm Average travel time, min Planning time, min Westbound Eastbound

19 Compare to Other Corridors Usual Top 10 among NC non-work zone freeway bottlenecks December 2018 ranked 10 th January 2019 ranked 7 th Vies with EB I-540 as worst in Division 5

20 Reported Crashes 1471 reported crashes in recent five years NC-147 bridge to I-540 bridge Crash rate per 100 million vm = 139 Compare to statewide urban interstate rate = 130 Fatal and injury rates also near statewide average 64% of crashes rear-end 44% of crashes 5 pm to 7 pm Only 9% of crashes Saturday and Sunday Over 90% of involved were light vehicles

21 400 Reported Crashes Volume growing just over 2% per year, crashes growing over 10% per year

22 It s a Local Commuter Problem Street Light data from DCHC MPO PM peak hour, eastbound Of traffic on I-40 approaching I % from I-40 west of NC % from NC % from Davis 13% from Miami 21% from Page

24 2045 Daily V/C From DCHC MPO

25 Bridges Constraints No room underneath Railroad No frontage roads Left entrance Weaves Need express lane configuration if widened?

26 Right of way NC-147 interchange Along I-40 Parallel routes NC-54 NC-147 to NC-540 $1.68 and two extra miles Opportunities US-70 as freeway US-421 to US-64 to Southern Outer Loop

27 It s important It s bad Summary Congestion, safety Not nearly the worst in the state PM peak, commuters, light vehicles, mainline Expected to get much worse In 2045 AADT of 340,000? V/C of 1.4? Constraints and opportunities

28 Thank You! Let s go fix some intersections and interchanges Joe Hummer , jehummer@ncdot.gov

30 MPO/NCDOT Projects for I-40 Short Term ( ) Mid-Term ( ) Long-Term (Beyond 2030) Other Planning Studies & Initiatives

31 Near Term ( ) I-40 Projects Interchange Projects: I-5700 Airport Blvd I-5506 Aviation Pkwy Auxiliary Lanes: I-5707 NC 55 to NC 147 (WB only) I-540 to Aviation Pkwy Parallel Routes East End Connector US 70 U Expressway NC 54 U Widening Aviation Parkway U-5811 McCrimmon Ave U-5828, U- 5747

32 Mid-Term ( ) I-40 Projects Widening I-5701 I-440 to Lake Wheeler Interchange Improvements I-5703 I-40/I-440/US1 Auxiliary Lanes I-5966 Aviation to Harrison Ave Managed Motorways I-6006 NC 147 to Wade Ave Parallel Routes US 70 U-5720 Expressway US 70 U-2823 Superstreet I-440 / US 70 I Interchange NC 147 U-5937 Operational Impvs NC 147 U Widening NC 147 U-5966 New location US 64 U Expressway Wade Ave U Widening

33 Long-Term (beyond 2030) I-40 / I-440/US1/I-87 Managed Motorways U-6101 I-40 Managed Lanes NC 54 Widening/Superstreet I-540 Managed Motorways & Managed Shoulders

34 Other Planning Studies & Initiatives Triangle Regional Tolling Study Triangle Regional ITS Plan Update Commuting Corridors Study Traffic Incident Management Program

35 Questions Alex Rickard, Capital Area MPO Aaron Cain, Durham Chapel-Hill Carrboro MPO David Keilson, NCDOT Division 5

36 I-40 on-ramp signals / managed freeway study Mike Surasky, WSP

37 I-25 Corridor in Colorado Being developed as part of Colorado DOT s RoadX program Currently under construction including ramp modifications, upgraded traffic detection, and back office changes. First deployment of Australian type of Managed Motorways in the US. Metering will also be deployed on system to system (freeway to freeway) interchanges. Management of the system will be cloud based to allow use of the STREAMS freeway management system. Providing a lot of lessons learned for NC

38 I-40 in Triangle Region Wade to NC 54 Feasibility study under way, completion by June Preliminary screening Analysis of required storage Analysis of Ramp Discharge Capacity Detection requirements, including detection templates for various interchange types High level cost estimates and environmental analysis Have completed traffic counts and analyzed ramp capacities, bottlenecks, and detection requirements Working with NCDOT on software/it concerns Beginning to develop ramp designs

39 TABLE DISCUSSION

40 Discussion prompts How might an existing project be improved/enhanced? What piece of an existing project might be separated and accelerated? What is something of little to no cost that might help (and wouldn t have to go through STI)?
