Welcome Project Team Parsons Brinckerhoff Darryl Phillips, P.E., PTOE David Cooper, P.E. McCormick Taylor Jennifer Threats Betsy Zang Carrie Hill Todays Meeting Progress to Date Needs Analysis

  2. Welcome • • •

  3. Project Team • Parsons Brinckerhoff – Darryl Phillips, P.E., PTOE – David Cooper, P.E. • McCormick Taylor – Jennifer Threats – Betsy Zang – Carrie Hill

  4. Today’s Meeting • Progress to Date • Needs Analysis • Measures of Effectiveness • Improvement Concepts • Next Steps

  5. Project Approach Completed to Date: • Public Input • Traffic Data Collection • Traffic Modeling and Analysis • Needs Analysis • Developing Improvement Concepts

  6. Public Input • Stakeholder Interviews • Public Meetings Nearly 2,200 • Website completed surveys • Online survey and shared over 17,000 interests and concerns Survey Visitors: 2,797 Completed Surveys: 2,179

  7. What We Heard Survey & Stakeholder I-376 Common Themes • • • • • • • • • • • • • • • • • • • • •

  8. Technical Studies Traffic Studies: • Traffic counts – Aerial photography – Origin-destination counts – Turning movement counts – ATR counts • Safety and Geometric studies • Alternate routes • Alternate modes

  9. Technical Studies Capacity Analysis: • Document Parkway congestion • Measure level-of-service on arterial roadways

  10. Technical Studies Network Model: • Models alternate routes • Calibrated to field data • Separate AM and PM models • Forecasts future conditions

  11. Technical Studies Network Simulation:

  12. Needs Analysis Purpose and Need • Conducted in accordance with PennDOT Publication 319 • Developed based upon: – Technical analysis – Public comment • Basis of evaluation of alternatives

  13. Needs Analysis Purpose: To improve traffic flow, improve safety, and improve multimodal travel options in the Parkway East Corridor Transportation Network, located in Allegheny County, Pennsylvania, which consists of the Parkway East (I-376) from the Fort Pitt Bridge to the Pennsylvania Turnpike/US 22 interchange, and also includes parallel and intersecting arterial roadways.

  14. Needs Analysis Needs: • The Parkway East is congested • Alternate routes are congested • Crash rates are above average • Parkway East does not meet existing design criteria • Parkway East travel times are unreliable • Multimodal transportation options are limited

  15. MOEs Measures of Effectiveness: • Ways to measure how improvements meet the goals of the project • Evaluation of Cost, Benefits, and Constraints

  16. MOEs Initial Screening: • Qualitative • Rank each MOE from 1-10 • Weight MOEs based on importance • Identify fatal flaws • Consider potential benefit-cost ratio • Determine options to advance

  17. Improvement Concepts Improvement Concepts: • Initial list of 100 based upon technical evaluation and public input • Screening to reduce number • Some projects programmed • Opportunities for early action

  18. Improvement Concepts Already Programmed: • Queue detection on Glenwood ramp • Glenwood off-ramp deceleration lane • Second/Bates/Hot Metal signal retiming • Bates Street Improvements • Improve bottleneck on Route 28 at Highland Park Bridge

  19. Improvement Concepts Review of Improvement Options: • Six stations • Conceptual at this stage • Detailed analysis will follow • Things we should know • Anything we’ve missed • Comment sheets

  20. Project Approach Next Steps: • Preliminary screening • Stakeholder email update • Detailed Analysis • Stakeholder Meeting #2 • Public Meeting • Identify Potential Projects • Implementation

  21. Group Discussion Questions and Discussion

  22. Next Steps Thank You!
