Appendix A. Glossary of Terms The following are some of the terms and acronyms are used to describe existing and proposed conditions in this Study: • ADA: American with Disabilities Act, typically used to refer to accessible pedestrian facilities, such as curb ramps and pedestria n push buttons at signalized intersections. • ADT: Average Daily Traffic, which is the average total number of vehicles that use a r oadway throughout the day. • Bicycle Boulevard: These are typically residential or low ADT streets that are designated to give bicyclists priority. They are usually demarca ted through pavement markings such as sharrows and signage. • BPAC: San Leandro’s Bicycle and Pedestrian Advisory Committee, an appointed group of San Leandro residents who provide input on City bicycle and pedestrian projects • Buffer: Striped area between a travel lane and a bicycle lane and/or a bicycle lane and on -street parking. It typically has chevron arrows or diagonal hatching to denote the buffer. It is used to provide separation and additional comfort between bicyclists and/or moving vehicles or p arked cars. Some bike lane buffers for separated bike lanes are made of concrete or landscaping. • Bulb Out: Extensions of the sidewalk environment at intersections, typically shadowing parking. They improve driver-pedestrian visibility at crossings and shorten crossing distances. • Bus Bulb: Similar to bulb outs, they are extensions of the sidewalk environment that typically shadow park ing, but are located at transit stops and are designed to accommodate the full length of a transit vehicle. They typically allow for in-lane stopping. • Bus Island: A dedicated area for transit users to wait and board transit vehicles. They are typically concrete and separated from the sidewalk by a separated bike lanes to mitigate bicycle-bus conflicts at transit stops. Bus islands typically allow for in-lane stopping. • Conflict Zone: Portions of bicycle lanes where drivers frequently merge across, such as the portion of a bicycle lane that right-turning automobiles merge into before the intersection. • Cross Section: The configuration of a roadway, including the amount of right-of-way dedicated to pedestrians, transit, bicyclists, and vehicles. • In-Lane Stopping: occurs when a bus bulb or bus island allows a transit vehicle to stop in the travel lane to on- and off-board at a transit stop. In-lane stopping mitigates the need for transit vehicles to merge into and out of traffic at transit stops. DRA F T
