Traffic Calming Workshop Purpose of Traffic Calming Slow - PowerPoint PPT Presentation

Traffic Calming Workshop Purpose of Traffic Calming Slow vehicular travel speeds Reduce the frequency and severity of collisions Reduce the need for police enforcement Reduce residential cut-through motor vehicle travel


  1. Traffic Calming Workshop

  2. Purpose of Traffic Calming • Slow vehicular travel speeds • Reduce the frequency and severity of collisions • Reduce the need for police enforcement • Reduce residential cut-through motor vehicle travel patterns • Increase safety for non-motorized street users • Increase access for all modes of transportation • Enhance the street environment

  3. Project Funding • Photo Red Light Funds – 15 red light cameras at 10 intersections throughout Spokane • Cameras implemented in 2008 • The program is a safety program designed to reduce red light violations and collisions in intersections. • Funding is expected to be available on an annual basis. • Minimum of $100,000 per district per year.

  4. What the Program Funds • Installation of – Traffic Control devices – Pedestrian and bicycle improvements – Physical roadway features • Transportation Studies • Project Designs

  5. Traffic Calming Projects • There is not a single tool to solve traffic issues and one tool that may work well in one area for a particular issue may not be effective in another area. • Typical Problems Traffic Calming Solves – Excessive Speeds – Excessive Volume – Lack of Safety

  6. Potential Speed Control Measures • Landscaping • Textured & Colored • Gateway Pavement • Stationary Radar Sign • On-street parking • Pavement Marking • Modern Roundabout • Traffic Circle • Narrowed Lane • Bumpout (Neckdown/Bulbout/Curb Extension) • Signage • Reduced Corner Radii

  7. Potential Volume Control Measures • Roadway Closures • Diverter • Turn Restrictions

  8. Potential Safety Measures • Bike Lanes • In-fill sidewalks • Marked Crosswalk – With pedestrian crossing island

  9. Project Selection Requirements 1. There is a $40,000 threshold unless there are identified matching funds (i.e. CDBG funds) 2. Each neighborhood can submit only 1 residential and 1 arterial application. 3. Applications must be singed or have a signed letter from the Neighborhood Council chair to be eligible. 4. Projects must be ranked 1 or 2 (projects should not hold the same ranking) 5. Project scope should stop at logical breaks 6. No dead-end or sidewalks that lead to nowhere 7. Consider whole street and whole neighborhood when choosing projects, outreach to the membership.

  11. Project Traffic Assessment

  12. Basic Analysis Process • Define The Problem • Is There a Realistic Solution? • Gather Facts For The Problem • Create Possible Solutions to The Problem • Review Possible Solutions and Select Your BEST Solution • Submit your BEST Solution

  13. Basic Analysis Process • Define The Problem – Clearly state what you believe to be the problem • Speeding? • Too many collisions - safety? • Too much volume? • Example – ABC Street has a lot of speeding cars with a lot of collisions and we want to reduce the number of collisions • This is potentially Speeding AND Safety

  14. Basic Analysis Process • Is There A Reasonable Solution? – Look at solutions that are realistic • Refer to the Traffic Calming Toolbox • Meet with City staff for help • Example – ABC Street should be closed to all traffic immediately • This is effective by not realistic for residents or emergency services – ABC Street should have a traffic circle or bump outs • This is realistic and still accommodates all users of the street

  15. Basic Analysis Process • Gather Facts For The Problem – What facts would help to determine our next steps? • Traffic counts • Speed counts • Collision records • Example – ABC Street has 1,000 cars a day, an average speed of 30 mph, and an average of 3 collisions per year • This is higher than usual volume and speed, collisions not unusual • ABC Street collisions all occurred at night and involved pedestrians

  16. Basic Analysis Process • Create Possible Solutions to The Problem – Look at available resources to brainstorm • Refer to the Traffic Calming Toolbox • Meet with City staff for help • Example – ABC Street possible solutions: • Traffic circle • Better street lighting if collisions are at night • Improve the closest arterial to make it more inviting • Interactive speed signs • Street bump outs

  17. Basic Analysis Process • Review Possible Solutions and Select Your BEST Solution – Look at the possible solutions and select your BEST • City staff can help • Select the solution you feel is most likely to help and be selected • Example – ABC Street needs a traffic circle MOST • This might be supported MOST by the neighborhood • Add street lights to it also at crossing points

  18. Basic Analysis Process • Submit your BEST Solution – Fill out the traffic calming application • Clearly define the problem • Identify your project solution • Submit the supporting information for your project • Example – ABC Street application • Be specific and fill out all the boxes!

  19. Past Project Examples • Maxwell and Elm Pedestrian Island and Crossing – Define The Problem • A lot of pedestrians during the summer for the pool • Speeding cars • Too many cars – Is There a Realistic Solution? • Neighborhood wanted a flashing light • Costs and seasonality of pedestrians were an issue • Look at other pedestrian options

  20. Past Project Examples • Maxwell and Elm Pedestrian Island and Crossing – Gather Facts For The Problem • Over 5,000 cars per day traffic volume • Average speed was 28 mph – posted 30 mph • Seasonal 20 mph speed limit zone • Over 80 pedestrians in an hour when the pool is open – Create Possible Solutions to The Problem • Pool staff put out signs daily • More pedestrian signs • Pedestrian refuge island

  21. Past Project Examples • Maxwell and Elm Pedestrian Island and Crossing – Review Possible Solutions and Select Your BEST Solution • Having pool staff put out signs was not safe • Portable signs put out by pool staff could be stolen • Hard concrete island in the median to protect pedestrians • Use of special pedestrian crossing signs – Submit your BEST Solution • Concrete pedestrian island • Pedestrian signing • Special pedestrian signing

  22. Past Project Examples • Maxwell and Elm Pedestrian Island and Crossing

  23. Past Project Examples • Montgomery Traffic Circles – Define The Problem • Cars going through the neighborhood to get to the light at Monroe • Speeding cars • Too many cars – Is There a Realistic Solution? • Neighborhood wanted to cut off traffic onto Montgomery • Take the traffic signal out at Montgomery and Monroe • Cut off traffic access on Northwest Blvd.

  24. Past Project Examples • Montgomery Traffic Circles – Gather Facts For The Problem • Over 1,800 cars per day traffic volume on a residential street • Average speed was 18 mph – speed limit is 25 mph • Trinity Catholic School on Montgomery • No pedestrian collisions at Montgomery – Create Possible Solutions to The Problem • Change signal • Chicane • Bump outs • Traffic circles

  25. Past Project Examples • Montgomery Traffic Circles – Review Possible Solutions and Select Your BEST Solution • Changing the traffic signal may not have much effect • Bump outs affect street drainage • Traffic circles would fit – Submit your BEST Solution • Traffic circles will fit and not effect street drainage • Change the signal timing to delay Montgomery more

  26. Past Project Examples • Montgomery Traffic Circles

  27. Potential NEW Project Example • Maxwell and Cedar – Define The Problem • Street alignment leads to speeding and neighborhood cut thru • Street alignment encourages circumventing the traffic signal • Encourages neighborhood speeding – Is There a Realistic Solution? • Block the street (emergency services issues) • Traffic circles or bumpouts • Change the street alignment

  28. Potential NEW Project Example • Maxwell and Cedar – Gather Facts For The Problem • Collect traffic volumes • Collect traffic speeds • Review collision history • Address long history of complaints – Create Possible Solutions to The Problem • Narrow the roadway • Install traffic circles or bumpouts • Change the street alignment
