  5. 5. What are speed cushions ?                              
  6. 6. How do I have speed cushions installed on my street? <ul><li>85 th Percentile Speed must exceed 35 miles per hour. </li></ul><ul><ul><li>If the speeds of all motorists are ranked </li></ul></ul><ul><ul><li>from slowest to fastest, the &quot;85th percentile </li></ul></ul><ul><ul><li>speed&quot; separates the slower 85% from the </li></ul></ul><ul><ul><li>fastest 15%. </li></ul></ul><ul><li>Must be included in a Neighborhood Traffic Management Plan (NTMP). The </li></ul><ul><li>City does not install speed cushions on individual streets if a traffic speed or </li></ul><ul><li>volume problem is diverted to another street </li></ul><ul><li>Traffic Plan must be approved by neighborhood, 25% of ballots must be returned </li></ul><ul><li>66% must be in favor of plan.

Street entering a through highway or street. </li></ul></ul><ul><ul><li>3. Unsignalized intersection in a signalized area. </li></ul></ul><ul><ul><li>4. Other intersections where a combination of high speed, restricted view, and serious accident record indicates a need for control by the STOP sign. </li></ul></ul><ul><ul><li>*2 Way to All Way Stop requires petition of residents. (600’ in both directions, of uncontrolled street. Approach traffic must be distributed 60% and 40%. </li></ul></ul>

  10. 10. Traffic Calming in CFW <ul><li>Background </li></ul><ul><li>- 1998 Speed Hump Program initiated. </li></ul><ul><li>- Original process required support of 2/3 of </li></ul><ul><li> respondents to petition, limited to residents located on street where speed humps were planned. </li></ul><ul><li>- 85 th percentile speed had to exceed 33 mph. </li></ul><ul><li>- 2004 Administrative process to install speed humps amended. </li></ul>
  11. 11. Traffic Calming in CFW <ul><li>2004 Neighborhood Traffic Management </li></ul><ul><li>Program (NTMP) process approved by City </li></ul><ul><li>Council. </li></ul><ul><li>- NTMP Process requires: </li></ul><ul><li>Neighborhood 95% built-out </li></ul><ul><li>Formation of Traffic Committee </li></ul><ul><li>Coordinate with neighborhood associations </li></ul><ul><li>85 percentile traffic speed must be 35mph </li></ul><ul><li>Development of Traffic Management Plan </li></ul>

Neighborhood Traffic Plans <ul><li>Existing Process </li></ul><ul><li>-Developing the Traffic plan. </li></ul><ul><li>T&PW & Neighborhood Traffic Committee hold meeting. </li></ul><ul><li>Neighborhood workshop to develop plan. </li></ul><ul><li>T&PW & Neighborhood Traffic Committee meet to review plan. </li></ul><ul><li>T&PW circulates preliminary plan to Fire and Police Department for review. </li></ul><ul><li>T&PW prepares ballot, distributed and collected by residents/volunteers. </li></ul><ul><li>25% of ballots must be returned and 66% must agree with the Plan </li></ul><ul><li>City Engineer gives final approval. </li></ul>
  13. 13. How does traffic calming work? <ul><ul><li>vertical deflections </li></ul></ul><ul><ul><li>horizontal shifts </li></ul></ul><ul><ul><li>roadway narrowings </li></ul></ul><ul><ul><li>Are intended to reduce speed and enhance the street environment for non-motorists. </li></ul></ul><ul><ul><li>Closures (diagonal diverters, half closures, full closures, and median barriers) </li></ul></ul><ul><ul><li>Are intended to reduce cut-through traffic by obstructing traffic movements in one or more directions </li></ul></ul>
  14. 14. Chicanes Horizontal Deflection Curb extensions that alternate from one side of the street to the other, forming S-shaped curves Can be formed by alternating on-street parking Good for locations where speeds are a problem, but noise associated with speed humps and related measures would be unacceptable
  15. 15. Chicanes
  16. 16. Chokers <ul><li>A narrowing of the street, often in mid-block, sometimes at an intersection. May be done with curb extensions, landscaping, or islands set in the street. </li></ul>
  17. 17. Chokers
  18. 18. Traffic Circles <ul><li>Raised islands placed </li></ul><ul><li>in intersections </li></ul><ul><li>Good for calming </li></ul><ul><li>intersections, especially </li></ul><ul><li>within neighborhoods where large vehicle traffic is not a major concern, but speeds, </li></ul><ul><li>volumes, and safety are problems </li></ul>
  19. 19. Diverter
  20. 20. Diverter
  21. 21. Partial Street Closure
  22. 22. Street Closure
  23. 23. Realigned Intersections (Modified Intersections) <ul><li>Changes in alignment that convert T-intersections with straight approaches into curving streets that meet at right angles </li></ul><ul><li>Traffic calming measure for </li></ul><ul><li>T-intersections </li></ul>
  24. 24. Center Island Narrowings <ul><li>Raised island along the centerline of a street </li></ul><ul><li>Often landscaped </li></ul><ul><li>Typically placed at neighborhood entrances </li></ul><ul><li>Can provide a pedestrian refuge </li></ul><ul><li>Good for entrances to </li></ul><ul><li>neighborhoods and wide streets where pedestrians need to cross </li></ul>
  25. 25. Raised Crosswalks/Speed Tables <ul><li>Speed tables with </li></ul><ul><li>crosswalk markings </li></ul><ul><li>Provides pedestrians with </li></ul><ul><li>a level street crossing </li></ul><ul><li>Pedestrians are more visible </li></ul><ul><li>to motorists </li></ul><ul><li>Good for locations where </li></ul><ul><li>pedestrian crossings occur </li></ul><ul><li>and vehicle speeds are </li></ul><ul><li>excessive </li></ul>
  26. 26. Textured Pavements <ul><li>Stamped pavement to create an uneven surface </li></ul><ul><li>Emphasize either an </li></ul><ul><li>entire intersection or a pedestrian crossing </li></ul><ul><li>Good for “main street” areas where there is substantial pedestrian activity and noise is not a major concern </li></ul>
  27. 27. Bike/Pedestrian Systems
  28. 28. Transportation Capital Needs - Next 10 Years $30 M Replace failing bridges… Riverside Drive over the Trinity River, E. Rosedale Street over Sycamore Creek, and W. 7 th Street over the Trinity Bridge Replacements $10 M Address need for Neighborhood Traffic Calming due to more traffic in our neighborhoods (trying to avoid the increasing congestion on arterial network) Traffic Calming $585 M $1.2 B $1.785 B Existing Needs New growth - 10 years Total Major Arterials $20 M Repair recently failed new streets Repair Premature Street Failures $40 M 2004 Bond Program funding will be exhausted this year New Traffic Signals/Street Lights $30 M Match to leverage Federal funds for needed transportation projects (freeway bottlenecks, rail safety, intersection improvements, etc.) Transportation Grant Projects $400 M 815 Lane Miles of “poor” streets…Goal = Reduce the number of “poor” lane miles by 20% in 10 years Neighborhood Street Reconstruction Need Impact Program
