Landscaping in the central island, in splitter islands (where appropriate), and along the approaches can benefit both public safety and community enhancement. The landscaping of the roundabout and approaches should:
- Make the central island more conspicuous;
- Improve the aesthetics of the area while complementing surrounding
streetscapes as much as possible; - Minimize introducing hazards to the intersection, such as trees, poles, walls, guide rail, statues, or large rocks;
- Avoid obscuring the form of the roundabout or the signing to the driver;
- Maintain adequate sight distances, as discussed in Chapter 6;
- Clearly indicate to the driver that they cannot pass straight through the intersection;
- Discourage pedestrian traffic through the central island; and
- Help blind and visually impaired pedestrians locate sidewalks and crosswalks.
