  1. 1. What can the ITE/CNU Guide for Walkable Streets do for Elgin? <ul><li>Lucy Gibson, P.E. </li></ul><ul><li>Smart Mobility, Inc. </li></ul>
  2. 2. The Elgin Pilot <ul><li>The Big Picture: How Elgin’s plans fit into the region, and will help shape Chicagoland’s Future. </li></ul><ul><li>How the CNU/ITE Manual supports Elgin’s plans </li></ul><ul><li>How Using the Manual differs from Conventional Practice (Engineering Myth-Busting) </li></ul><ul><li>Challenges in applying to two Locations in Elgin: National Street and Route 20 </li></ul>
  3. 3. ELGIN’S PLANS WITHIN THE REGION <ul><li>The Elgin Pilot </li></ul>
  4. 4. Chicago Metropolis 2020
  5. 5. Choices for the Region
  6. 6. A different approach is needed to address congestion – The Metropolis Plan
  7. 7. HOW WILL THE MANUAL SUPPORT ELGIN’S PLANS? <ul><li>The Elgin Pilot </li></ul>
  8. 8. Elgin’s Plans: Implementing the Metropolis Vision
  9. 9. Downtown Elgin Vision <ul><li>A Vibrant Center City </li></ul><ul><li>A community that promotes downtown Elgin as a welcoming place to live, work, shop, entertain, and visit – the “heart” of the community. </li></ul><ul><li>A community that promotes more attractive, useable downtown plazas and parks; improves the pedestrian character of the streetscape ; creates greenways; and improves access to the riverfront. </li></ul><ul><li>A community that promotes increased use of transit services, and walking and biking between the center city and the surrounding community. </li></ul>
  10. 10. Mixed Use Centers <ul><li>The mixed use service center land use designation provides for . . . residential, institutional, office, service, and retail uses in a compact and pedestrian oriented setting . . . . characterized by vertical, higher density at its core, transitioning to less intensity and predominantly single family residential at its edge. </li></ul>
  11. 11. Where does the ITE/CNU Manual Apply?
  12. 15. HOW THE ITE/CNU MANUAL DIFFERS FROM CONVENTIONAL PRACTICE <ul><li>The Elgin Pilot </li></ul>
  13. 16. Empirical vs. Theoretical Design <ul><li>AASHTO is Theoretical, with design criteria based on physics, behavior of vehicles and drivers. </li></ul><ul><li>New Urbanism is Empirical. Community design principles are developed based on detailed observations of what works well, is proven successful. </li></ul><ul><li>ITE/CNU guidelines are a hybrid. </li></ul>

  15. 21. America’s Newest Multiway Boulevard
  16. 22. Octavia Boulevard
  17. 24. How is ITE/CNU Manual Different? <ul><li>Context Based, for walkable communities – To use these guidelines, you need to clearly define your future context. </li></ul>

  27. 34. Excelsior and Grand, 2003
  28. 35. How is ITE/CNU Manual Different? <ul><li>Network based – Need to consider future network to create a walkable place. </li></ul>
  29. 42. NEW URBAN TRAFFIC ENGINEERING <ul><li>The Elgin Pilot </li></ul>
  30. 43. Rethinking our old ways (or Engineering Myth Busting) <ul><li>Arterials are for driving, not for walking (or biking or shopping or placemaking. . . ) </li></ul><ul><li>Mobility = Speed </li></ul><ul><li>Intersections , and street connectivity, are bad for traffic </li></ul>
  31. 44. Great Streets are Great Places
  32. 45. Mobility = Capacity <ul><li>Providing Mobility has been equated to providing high speed driving on arterials. </li></ul><ul><li>High speeds are: </li></ul><ul><ul><li>highly dangerous to pedestrians, </li></ul></ul><ul><ul><li>toxic to placemaking, and </li></ul></ul><ul><ul><li>most importantly, not needed for maximizing vehicular throughput, or capacity. </li></ul></ul>Mobility = Speed
  33. 47. New Way to Define Mobility <ul><li>Multimodal: Conditions for mobility for all modes should be considered and balanced </li></ul><ul><li>For Vehicles: </li></ul><ul><ul><li>Provide for peak hour capacity to avoid congestion </li></ul></ul><ul><ul><li>Keep traffic moving at a speed that does not pose a threat to pedestrians, nor detract from the area. </li></ul></ul><ul><ul><li>Provide a network that increases capacity and allows for choices of routes. </li></ul></ul><ul><li>For Pedestrians: Traffic Speeds less then 35 mph </li></ul>
  34. 48. Conventional Arterial Design
  35. 80. The Value of a Grid
  36. 98. CHALLENGES TO IMPLEMENTING WALKABLE MAJOR STREETS <ul><li>The Elgin Pilot </li></ul>
  37. 99. Conventional Network Design <ul><li>Concentrate traffic crossing or entering arterials into as few intersections as possible. </li></ul><ul><li>This allows high speed travel between intersections, but the intersections themselves must be very wide. </li></ul><ul><li>High speeds, lots of lanes for pedestrians to cross = Not Walkable. </li></ul>
  38. 100. Route 20 Corridor Study <ul><li>Takes a conventional approach to arterial planning: “Predict and Provide” </li></ul><ul><li>Uses suburban or rural design criteria </li></ul>
  39. 102. Route 20 Corridor Study <ul><li>Recommendations are not oriented to support walkable development in the Mixed Use Centers. </li></ul>
  40. 103. Conventional Guidelines Impair Network Development <ul><li>Elgin Development Standards: </li></ul><ul><ul><li>Arterial Streets are to be limited to a maximum and a minimum of four (4) street intersections with collector streets for each mile of length. Such intersections are to be located a minimum of one thousand (1,000) feet apart. </li></ul></ul><ul><li>CNU/ITE Guidelines </li></ul><ul><ul><li>Block Lengths of 300 to 600 feet; pedestrian crossings every 300 to 600 feet. </li></ul></ul>

  42. 105. General Plan – Future Arterials
  43. 106. General Plan – street connectivity grid
  44. 107. General Plan – Future uses and n’hood centers
  45. 108. Improve Arterial Connectivity <ul><li>Designate Mixed Use Centers as Urban Areas, which allow smaller blocks, on-street parking, and lower speed limits. </li></ul><ul><li>Adopt the ITE/CNU Walkable Street Guide as official policy (Texas DOT Example). </li></ul>
