  12. ALTERNATIVE EVALUATION AND SCREENING PROCESS Develop Initial Alternatives Fatal Flaw Screening Eliminate Alternatives Purpose & Need Screening Eliminate Alternatives Level I Screening Eliminate Alternatives Level of Service , Right-of-Way, Stakeholder Input Level II Screening Level of Service , Right-of-Way, Eliminate Alternatives Stakeholder Input, Environmental Concerns, Cost PREFERRED ALTERNATIVE

  13. PRIMER – INTERCHANGES Service Interchanges  Conventional Diamond  Single Point Urban  Partial Cloverleaf  Diverging Diamond  Full Cloverleaf  Indirect

  14. CONVENTIONAL DIAMOND  Lower Capacity STOP, SIGNAL, OR ROUNDABOUT  Typically Rural Settings  Low Cost  Good Driver Expectancy  Good Bicycle/ Pedestrian STOP, SIGNAL, OR Integration ROUNDABOUT

  16. FULL CLOVERLEAF  Efficient Crossroad WEAVE WEAVE  Undesirable Weaving  Large Footprint = Larger Property Impact  Difficult Bicycle/ Pedestrian WEAVE Integration WEAVE

  18. PARTIAL CLOVERLEAF  1-3 Loop Ramps to SIGNAL Handle Certain Movements Accommodate High  Left Turn Volumes Adaptable in  Restricted Right-of- Way Situations WEAVE  Moderate Bicycle / SIGNAL Pedestrian Integration

  21. SINGLE POINT URBAN (SPUI)  Improved operations over conventional diamond Higher cost due to larger  bridge Good for restricted ROW  conditions  Better cross street signal spacing for close adjacent signals  Good for Bicycle/ Pedestrian Integration

  23. DIVERGING DIAMOND (DDI)  Accommodate High SIGNAL Left Turn Volumes  Same general footprint as conventional diamond but higher capacity  Good for Bicycle / Pedestrian SIGNAL Integration

  24. Reagan M Memoria ial T l Tollw lway ( (I-88) at I IL 59 ( (Naperville ille)

  25. DIVERGING DIAMOND VIDEO DEMO

  26. INDIRECT SIGNAL SIGNAL Used in restricted right-of-  way conditions or when the adjacent roadway network precludes a traditional interchange type  Circuitous Travel Routing  Poor for Driver Expectancy Good for Bicycle/  Pedestrian Integration SIGNAL SIGNAL

  28. PRIMER – CORRIDOR TOOLS Where does IL 47 go? Alignment Typical Sections What does IL 47 look like?

  29. PRIMER – CORRIDOR TOOLS Existing Alignment - Asymmetrical New Symmetrical Widening Alignment Widening Alignments

  30. PRIMER – CORRIDOR TOOLS EXAMPLE TYPICAL SECTION ELEMENTS RAISED MEDIAN TURF OR PAVED OUTSIDE SHOULDER TRAVEL LANES OUTSIDE DITCH CURB AND GUTTER STORM SEWER SHARED USE PATH

  31. PRIMER – CORRIDOR TOOLS Access Management  Medians  Entrance Relocation  Intersection Spacing  Right-In/Right-Out (RI/RO)  Access Consolidation  ¾ Access ¾ ACCESS RIGHT-IN/RIGHT-OUT RIGHT-IN/RIGHT-OUT AND LEFT-IN ¼ MILE MINIMUM SIGNAL SPACING

  32. PRIMER – CORRIDOR TOOLS Intersection Improvements  Traffic Controls  Yield  Stop (Two-Way Stop, All-Way Stop)  Traffic Signal  Roundabout  Turn Lanes (Channelization)  Pedestrian and Bike Crossings  Crosswalks (At-Grade) Grade Separations 
