  6. Alternative Development Process PURPOSE AND NEED REPORT Identify Stakeholders Alternative Development Process Identify Context Range of Alternatives Evaluate Alternatives Preferred Alternative Define Problem Considerations Stakeholder Considerations / Community Assets Environmental Considerations / Compatibility with the Environment Engineering Considerations / Transportation Needs

  7. Purpose and Need Development PURPOSE AND NEED REPORT STAKEHOLDER INPUT TECHNICAL ANALYSIS • CONTEXT SURVEY • PROBLEM STATEMENT • CRASH DATA ANALYSIS • TRAFFIC DATA ANALYSIS PUBLIC AND AGENCY COORDINATION

  8. Project Purpose The purpose of the proposed action is to provide an improved transportation facility in the Interstate 55 and Weber Road Interchange project study area. The specific needs to be addressed include safety, operational, and capacity deficiencies.

  9. Purpose and Need Need: Improve Safety Technical Analysis Community Context Survey Community Advisory Group

  10. Purpose and Need Need: Address Operational Deficiencies Technical Analysis Community Context Survey Community Advisory Group

  11. Purpose and Need Need: Improve Capacity Technical Analysis Community Advisory Group Community Context Survey

  12. Alternative Development Process Identify Stakeholders Alternative Development Process Identify Context Range of Alternatives Evaluate Alternatives Preferred Alternative Define Problem • Brainstorm alternatives with stakeholders • Solicit alternatives from agencies • Develop alternatives with project team

  13. Preliminary Alternatives • Interchange Improvements • Weber Road Improvements • Other mode accommodations

  14. Preliminary Alternatives • Interchange Improvements • Weber Road Improvements • Other mode accommodations

  15. Interchange Improvements • CLOVERLEAF • Free-flowing traffic • Large footprint • Weaving sections • Not pedestrian friendly

  16. Interchange Improvements • Partial Cloverleaf • No weaving • Some free-flowing movements • Some signal control • Smaller footprint in some quadrants

  17. Interchange Improvements • Diamond • Signal controlled intersections • Smaller footprint

  18. Interchange Improvements • Split Diamond • Signal controlled intersections • Access distributed at two locations • Frontage road system

  19. Interchange Improvements • Single Point Urban • Diamond (SPUDI) • Small footprint • One signalized intersection • Large structure

  20. Interchange Improvements • Diverging Diamond • Small footprint • Accommodates heavy left turn traffic • Free flow Interstate entrances • Driver unfamiliarity

  21. Veterans Parkway Interchange Improvements IL Route 126

  22. Preliminary Alternatives • Interchange Improvements • Weber Road Improvements • Other mode accommodations

  23. Weber Road Improvements Added Lane Added Lane Existing Lanes • Additional Capacity

  24. Weber Road Improvements • Lighting

  25. Weber Road Improvements Raised Median and Physically Separated Turn Lanes • Access Management

  26. Weber Road Improvements • Additional turn lanes • Improved traffic signal coordination • Turn prohibitions • Improved signage/striping • Pedestrian/Bicyclist accommodations

  27. Preliminary Alternatives • Interchange Improvements • Weber Road Improvements • Other mode accommodations

  28. Other Mode Accommodations • Pedestrian/Bicycle access over I-55 • PACE Park-N-Ride • Connect existing bike path network

  29. Alternative Development Process Identify Stakeholders Alternative Development Process Identify Context Range of Alternatives Evaluate Alternatives Preferred Alternative Define Problem • Confirm alternatives meet Purpose and Need and transportation performance measures • Compare impacts to natural and built environment

  30. Transportation Evaluation Criteria NEED Improve Safety • Assess existing conditions • Evaluate safety performance of each alternative • Performance metrics may include: • Adherence to safety standards • Projected change in crashes from 2040 baseline • ADA Compliance • Pedestrian/bicycle compatible Address Operational Deficiencies Improve Capacity

  31. Transportation Evaluation Criteria NEED Improve Safety • Assess existing conditions • Evaluate alternatives on addressing design issues • Performance metrics may include: • Design deficiencies • Right-of-Way • Construction Costs Address Operational Deficiencies Improve Capacity

  32. Transportation Evaluation Criteria NEED Improve Safety • Baseline condition will be 2040 (no improvements) • Evaluate alternatives on projected changes in travel conditions • Performance metrics may include: • Level of Service (LOS) • Right-of-Way • Construction Costs Address Operational Deficiencies Improve Capacity

  33. Environmental Evaluation Criteria

  34. Alternative Evaluation Initial Alternatives Eliminate Alternative(s) Fatal Flaw Screening Purpose & Need Screening Eliminate Alternative(s) • Round 1 Analysis • Level of Service (LOS) • Right of Way • Stakeholder Input Eliminate Alternative(s) • Round 2 Analysis • Environmental Impacts • Level of Service (LOS) • Right of Way • Costs • Stakeholder Input Eliminate Alternative(s) Preferred Alternative

  35. Alternative Development Process Identify Stakeholders Alternative Development Process Identify Context Range of Alternatives Evaluate Alternatives Preferred Alternative Define Problem • Detailed engineering and environmental analysis of remaining alternatives • Evaluate performance, impacts, and costs • Recommend preferred alternative

  36. Next Steps • Public Meeting (Fall 2011) • Present the results of technical screening • Identify alternatives to carry forward FINDING OF NO SIGNIFICANT IMPACT (FONSI) DETAILED ENVIRONMENTAL AND TECHNICAL STUDIES PREFERRED ALTERNATIVE & ENVIRONMENTAL ASSESSMENT (EA) DEVELOP PURPOSE AND NEED IDENTIFY POSSIBLE ALTERNATIVES EVALUATE ALTERNATIVES IDENTIFY DEFICIENCIES START P U B L I C I N V O L V E M E N T 2010 2011 2012 STUDY MILESTONE PUBLIC MEETING PUBLIC HEARING
