Title: Considerations for Accommodating Visually Impaired Pedestrians at Roundabouts
Abstract: As roundabouts become more popular in North America, issues arise that require a designer to accommodate all people and modes safely in a roundabout. Roundabouts generally, have significant safety benefits over other traffic control devices for vehicles and therefore are considered useful to improve safety primarily as drivers must make complex decisions at traffic signals where in a roundabout the decision making is simplified in a slower environment. However this traffic control measure has some drawbacks including the accommodation of visually impaired pedestrians and the perceived need by some to have audible cues. Applications such as the Hawk system (a series of signal phases), actuated flashing beacons with audible cues, and tactile devices are discussed in the report. A case study is presented that addresses visually impaired pedestrian considerations at a one-lane roundabout. Finally, an overview of future design and education considerations is given, which is of particular importance for jurisdictions where roundabouts are being introduced.
