Managed Lanes Overview
Managed lanes are designated lanes or roadways within highway rights-of-way where the flow of traffic is managed by restricting vehicle eligibility, limiting facility access, or collecting variably priced tolls.

Project Phasing Managed Lanes projects need to address key issues
early in the process through the development of T&R, ConOps and PDEA Studies.

US-74 Managed Lanes Study
US-74 Managed Lanes Study
• Stand alone study to evaluate Managed Lanes on US-74-part of NCTA Toll operations on-call
• Administered by Turnpike Authority with support from various NCDOT departments, CDOT, others
• First opportunity for NCDOT to develop Managed Lanes policy
• Precursor to US-74 NEPA projects

Project-Components
• Concept of Operations (ConOps)-Statewide and Corridor Level
• Traffic and Revenue (T&R) Reports • Design and Constructability Report
• Functional/Conceptual Plans in Support of NEPA
Studies
• Operation and Maintenance Costs

Concept of Operations(ConOps)
Concept of Operations (ConOps) • The ConOps was prepared and will be used as a roadmap for the
development, implementation, and operation of a Managed Lanes facility along US-74 (Independence Boulevard) in Charlotte, North Carolina.
• A starting point that will continue to be refined as projects move forward
• Global policies applicable to all managed lanes projects
• Policies specific to the US 74 project • Document important for NCTA/NCDOT as they move forward on all
managed lanes projects
ConOps Overview
• Stakeholder Roles • Interagency Agreements • Operational Policies • Business Rules • Public Education & Outreach • ITS and Toll Systems • Performance Measures • Design Issues • Operational Analyses • Implementation Plan • Risk Analysis • Decision Matrix

Traffic & Revenue(T&R)
Traffic & Revenue - Basics
• Traffic volumes used to determine financial feasibility
• Three levels of T&R - Sketch, Preliminary and Investment Grade
• US 74 project - Sketch and Preliminary • Investment grade - to be reviewed by bond rating
agencies and investors Turnpike 101, 11/20/2006 at http://www.ncdot.gov/turnpike/download/TP101_NEPA_Traffic_Forecasting_Analysis_HNTB.pdf
Major Decisions – US-74
• HOT and “every one pays” models - Both were run for various scenarios
• Throughput, Reliable Travel and Revenue Maximization were all considered
• NC Quick Pass/Bill by Mail
• Dynamic Tolling
• Ingress/Egress Points
T&R - Project Phasing
• “Starter”: One reversible Lane for Segment 1 (I-277 to Albemarle Road) and 1 Express Lane in each direction for Segment 2 (Albemarle to Wallace Lane)—2017 to 2025
• “Ultimate 1”: Two Express Lanes in each direction from I-277 to I-485 (operating in median)
• “Ultimate 2”: One Express Lane in each direction from I-277 to I-485 (operating in median)
T&R - Project Phasing
• “Ultimate 3”: Two Express Lanes in each direction from I-277 to I-485 (Segment 4-Sardis North to I-485 as Elevated)
• “Ultimate 4”: One Express Lane in each direction from I-277 to I-485 (Segment 4 -Sardis North to I-485 as Elevated)

Design and Construction Challenges
Design & Construction Challenges
• A report containing an overview of the design and construction
challenges of the US-74 Scenarios.
• The report discusses both general challenges for managed lane projects and challenges specific to each of the T&R scenarios analysed for this project.
• Safety and “Hot spot” traffic analysis were part of this report
• Ingress and Egress for various scenarios were studied • Visio Diagrams (straight line diagrams) were developed to illustrate
all the T&R Scenarios.
US-74 Next Steps
• US-74 Managed Lanes Study Final Report submitted in April 2014
• NCDOT-Reprioritization-Results-Next TIP-Dec 2014? • U-5526 PDEA study (conversion to Managed Lane on US-74)
• Refine Operations and Maintenance Costs • Functional Designs • Refine T&R-Phase II/Project Specific • Design • Operational Assessment • Construction-2016?
