Gateway Speed Tables

Raised concrete elevating to four inches above asphalt with brick paver platform on top.

Pro: Slows traffic; may reduce cut through and lower volume.

Con: Some loss of on-street parking; can emIT low level noise as autos travel over brick pavers.

Medians

Concrete curb creates a landscaped rectangle in varying sizes in center of street. Can be used as a neighborhood gateway technique.

Pro: Slows traffic; may reduce cut through and lower volume.

Con: Loss of on street parking and bike lanes.

Traffic Circles & Roundabouts

A landscaped circle of at least eight feet in radius halts straight movements by forcing autos to move right and travel around the circle; approaches are usually controlled by yield signs.

Pro: Slows traffic; can be used instead of stop signs.

Con: Bicyclists and pedestrians must be more cautious; possible loss of on street parking.

Bulb Outs, Neck-downs, or Curb Reductions

Concrete curb defines a half circle that is sometimes accompanied by a speed table, crosswalk, or designated on street parking; narrows street; often used at intersections to discourage traffic from
entering a street. Can be used as a neighborhood gateway technique.

Pro: Slows traffic; provides pedestrians with shorter crossing distances if utilized at crosswalk; may reduce cut through and volume.

Con: Can result in a loss of on-street parking and bicycle lanes
and impact stormwater drainage.

Bicycle Lanes

Three or four foot wide striped lanes along side curb and/or gutter of roadway.

Pro: Visually narrows; provides and promotes safe routes for cyclists.

Con: Loss of on street parking.

Residential Sidealks

Five-foot concrete paths are laid to offer safe walking routes to pedestrians.

Pro: Safety for pedestrians; visually narrows the street.

Con: May result in loss of landscaping in City-owned right-of-way.
Please see Residential Sidewalk Brochure for additional information on how to request the installation of sidewalks.

Diverters, Semi Diverters & Delineators

Concrete curb creates a landscaped rectangle in varying sizes on either side of an intersection allowing for traffic to travel in only one direction at the diverter thus halting certain movements.

Pro: Reduces cut through, volume; slows traffic.

Con: Residents of the street may find getting home a more cumbersome effort.

Speed Humps and Tables

Asphalt is formed to raise four inches off pavement.

Pro: Reduce cut through, volume; slows traffic.

Con: Higher speeds can actually render humps less effective;
not aesthetically pleasing.

Rumble Strips

Raised plastic markers, or RPM's, are adhered to the pavement to alerts drivers to proceed cautiously at certain roadway segments such as sharp curves, schools, parks, playgrounds, and mid-block crosswalks.

Pro: Slows traffic; may reduce cut through.

Con: Noise emitted may be undesirable to adjacent homes.
