This report will be of interest to individuals and groups with a stake in the location and design of bus stops. These groups include public transportation organizations, public works departments, local departments of transportation, developers, and public and private organizations along or near bus routes. The research evaluated bus bulbs, an innovation in the design of bus stops found in several major North American cities. A bus bulb is a section of sidewalk that extends from the curb of a parking lane to the edge of a through lane. They are also known as curb extensions, nubs, and bus bulges.
