• NE 28th Street Traffic Calming Initial Survey:

    The City of Bellevue Transportation Department has heard from people in Northeast Bellevue about speeding concerns on NE 28th Street between 164th Avenue NE and Ardmore Park (169th Avenue NE). 

    This portion of NE 28th Street was evaluated against all other requests for traffic calming in the city—a list of 100 locations—and was rated highly for action given vehicle speeds, community support, and proximity to parks and schools.

    As we start to design this project, we’d like to get feedback from residents in the Sherwood Forest neighborhood to help inform the design of speed management countermeasures on NE 28th Street. We often try to implement multiple treatments along a corridor to maximize the potential speed reduction impact. Countermeasures will be selected based on design considerations, community feedback, desired goals, and budget.

    Traffic Calming Treatments

    We’d like to understand your perspective on the following speed reduction treatments that are being considered for the corridor. The treatments being considered include:

    • Entry treatments
    • Medians (with or without entry treatments)
    • Lane striping
    • Round mountable circles (Speed Mounds)
    • Traffic Circles
    • Speed humps
    • Speed cushions

    Entry treatments:   
    An entry treatment is a raised island in the center of a roadway, or a pavement treatment such as a stamped brick pavement that identifies the entrance to a neighborhood. It is placed in the roadway to define the main entrance into a neighborhood. The goal of an entry treatment is to visually identify to drivers that they are entering a neighborhood, and are slightly raised so they should reduce speeds.

    I like the idea of entry treatments to reduce speeds.

    Medians (with or without entry treatments) 
    Medians are raised islands placed in the center of a roadway to separate opposing traffic. They can be placed mid-block or at entrances into neighborhoods. Medians are used to narrow the roadway and are often landscaped to provide a visual enhancement and create a perception of a narrower roadway. They can be used in conjunction with a pedestrian crossing to provide a refuge area. They can also be used in conjunction with entry treatments at 164th Avenue NE.

    I like the idea of medians to reduce speeds.

    Lane striping: 
    Lane striping helps to define the roadway. Whether installed with paint or buttons, it can delineate parking areas, travel lanes, bike lanes, and even walking areas. While there are many goals with lane striping, the primary goal of lane striping on NE 28th Street would be to discourage speeding by narrowing the vehicle travel lanes.

    I like the idea of lane striping to reduce speeds.

    Round mountable circles (Speed Mounds) 
    Round mountable circles are slightly raised (less than a speed cushion) treatments that are placed in the middle of an intersection. Like brick entry treatments, drivers can drive over the circle. The goal of the circles is to help break sightlines along the corridor and, with the raised element, encourage people to slow down when approaching and traveling around or over it.

    I like the idea of round mountable circles to reduce speeds.

    Traffic Circles:  
    A traffic circle is a raised circular island located in the center of an intersection. This design requires vehicles to keep right and travel through the intersection in a counterclockwise direction around the island. The shape and size of the traffic circle is determined by the size of the intersection. Traffic circles can be placed at four-legged and three-legged intersections. Installations of traffic circles can be very effective at reducing the number of vehicle collisions at an intersection.

    I like the idea of using Traffic Circles to reduce speeds.

    Speed humps:
    Speed Humps have been used in the City of Bellevue since 1985 as a technique to reduce vehicle speeds. A speed hump is a raised area of roadway pavement approximately 3 inches in height. They are different from the more severe speed bumps that you may find in parking lots. Because speed humps and other physical devices impact emergency response times, they are limited to streets where they are most needed. Multiple speed humps are generally installed along a corridor to maximize effectiveness. The goal of speed humps is to slow down vehicles.

    I like the idea of speed humps to reduce speeds.

    Speed cushions:  
    Speed cushions are similar to speed humps, but they have gaps to allow for the expedient passing of emergency vehicles. Typically speed cushions consist of two or more raised and rounded areas of pavement placed laterally across a road. There are gaps for emergency vehicles to pass through without significant jostling or displacement. Like speed humps, multiple speed cushions are generally installed along a corridor to maximize effectiveness. Non-emergency vehicles are generally too narrow to travel through the gaps and must drive over the bump, helping to meet the goal of reducing vehicle speeds.
