To the editor:
A parent of one of my students asked me to write you a letter about "roundabouts" since one of my duties is to teach blind and visually impaired individuals how to negotiate them. Roundabouts are a method of traffic control that fosters the continuous movement of vehicles. One has been constructed and others are being discussed for Louisiana Street. I would like to register my opposition to the construction of these circles in areas where a high volume of pedestrian traffic is expected, for they are dangerous for all pedestrians.
In November 1999, the U. S. Architectural and Transportation Barriers Compliance Board (The Access Board) published "Accessible Rights-of-Way: Sidewalks, Street Crossings, Other Pedestrian Facilities: A Design Guide." In Chapter 3, "Pedestrian Accessibility," it states that "those who are blind or have low vision are concerned about the lack of crossing opportunities at roundabouts and other unsignalized traffic circles. Visual observation is the only way to identify and select a gap for crossing at these locations. Analyzing traffic sounds is not a technique that can be effectively applied to crossings at these and other continuous-flow intersections, including many free right turn locations. Where traffic volume or speed is high, pedestrians with vision impairments (as well as children, pedestrians who have cognitive disabilities, and those that travel slowly) must often choose an alternate route that avoids such intersections."
It further states that, "At unsignalized street crossings, including roundabouts, pedestrians who use wheelchairs are at a higher risk of being struck by moving vehicles..."
For the safety of all of our citizens, I urge that a public dialogue be initiated regarding the further development and implementation of this traffic-control plan. Pedestrian safety should be the primary concern at any street crossing. The use of "roundabouts" may or may not solve the traffic problem; however, the result may be other, more tragic, consequences.
