What are speed cushions ?

How do I have speed cushions installed on my street?

•85th Percentile Speed must exceed 35 miles per hour.

If the speeds of all motorists are ranked from slowest to fastest, the "85th percentile speed" separates the slower 85% from the fastest 15%.

•Must be included in a Neighborhood Traffic Management Plan (NTMP). The City does not install speed cushions on individual streets if a traffic speed or volume problem is diverted to another street

•Traffic Plan must be approved by neighborhood, 25% of ballots must be returned 66% must be in favor of plan. Resident volunteers must distribute and collectthe ballots.

Traffic Control Devices

A sign, signal, marking or other device used to regulate, mark or guideTraffic placed on, over, or adjacent to a street, highway, pedestrian facility, or Shared-use path by authority of a public agency having jurisdiction

Stop Sign Warrants

Because the STOP sign causes a substantial inconvenience to motorists, it should be used only where warranted.

A STOP sign may be warranted at an intersection where one or more of the following conditions exist:

1.Intersection of a less important road with a main road where application of the normal right-of-way rule is unduly hazardous.

2. Street entering a through highway or street.

3. Unsignalized intersection in a signalized area.

4. Other intersections where a combination of high speed, restricted view, and serious accident record indicates a need for control by the STOP sign.

*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%.

Can we lower the speed limit in our neighborhood?

30 mph, unless reduced by local ordinance

City Council may reduce the speed limit to 25 mph, in

accordance with Transportation Code, Section 545.356

• Street must be 35 feet or less in width

• Vehicular parking must not be prohibited. • Determination by local governing body that existing

speed limit is unreasonable or unsafe.• Must be posted at reduced speed

Traffic Calming in CFW

• Background - 1998 Speed Hump Program initiated.

- Original process required support of 2/3 of respondents to petition, limited to residents

located on street where speed humps were planned.

- 85th percentile speed had to exceed 33 mph. - 2004 Administrative process to install speed humps amended.

Traffic Calming in CFW• 2004 Neighborhood Traffic Management

Program (NTMP) process approved by City

Council.

- NTMP Process requires:• Neighborhood 95% built-out• Formation of Traffic Committee• Coordinate with neighborhood associations• 85 percentile traffic speed must be 35mph• Development of Traffic Management Plan

Neighborhood Traffic Plans

• Existing Process

-Developing the Traffic plan. T&PW & Neighborhood Traffic Committee hold meeting. Neighborhood workshop to develop plan. T&PW & Neighborhood Traffic Committee meet to review plan. T&PW circulates preliminary plan to Fire and Police Department for

review. T&PW prepares ballot, distributed and collected by

residents/volunteers. 25% of ballots must be returned and 66% must agree with the Plan City Engineer gives final approval.

How does traffic calming work?

•vertical deflections

• horizontal shifts

•roadway narrowings

Are intended to reduce speed and enhance the street environment for non-motorists.

•Closures (diagonal diverters, half closures, full closures, and median barriers)

Are intended to reduce cut-through traffic by obstructing traffic movements in one or more directions

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 wherespeeds are a problem, butnoise associated withspeed humps and relatedmeasures would beunacceptable

Chicanes

Chokers• 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.

Chokers

Traffic Circles

Raised islands placedin intersections

Good for calmingintersections, especiallywithin neighborhoods where large vehicle traffic is not a major concern, but speeds,volumes, and safety are problems

Diverter

Diverter

Partial Street Closure

Street Closure

Realigned Intersections(Modified Intersections)

Changes in alignment that convert T-intersections with straight approaches into curving streets that meet at right angles

Traffic calming measure forT-intersections

Center Island Narrowings

Raised island along the centerline of a street

Often landscaped

Typically placed at neighborhood entrances

Can provide a pedestrian refuge

Good for entrances to neighborhoods and wide streets where pedestrians need to cross

Raised Crosswalks/Speed Tables

Speed tables withcrosswalk markings

Provides pedestrians witha level street crossing

Pedestrians are more visibleto motorists

Good for locations wherepedestrian crossings occurand vehicle speeds areexcessive

Textured Pavements

Stamped pavement to create an uneven surface

Emphasize either anentire intersection or a pedestrian crossing

Good for “main street” areas where there is substantial pedestrian activity and noise is not a major concern
