A bicycle boulevard, sometimes referred to as a neighborhood greenway,〔https://www.portlandoregon.gov/transportation/50518〕 neighborway,〔https://louisvilleky.gov/government/bike-louisville/louisville-neighborways〕 neighborhood bikeway〔http://www.co.washington.or.us/LUT/Divisions/TrafficEngineering/DesignInformation/neighborhood-bikeway-plan.cfm〕 or neighborhood byway〔http://www.slcgov.com/transportation/whatisabyway〕 is a type of bikeway composed of a low-speed street which has been "optimized" for bicycle traffic.〔http://nacto.org/publication/urban-bikeway-design-guide/bicycle-boulevards/〕 Bicycle boulevards discourage cut-through motor-vehicle traffic but allow local motor-vehicle traffic. They are designed to give priority to bicyclists as through-going traffic. They are intended as a low-cost, politically popular way to create a connected network of streets with good bicyclist comfort and/or safety. Bicycle boulevards attempt to achieve several goals: * discouragement of non-local motor vehicle traffic; * low speed limits; * low motor-vehicle traffic volumes; * free-flow travel for bikes by assigning the right-of-way to the bicycle boulevard at intersections wherever possible; * traffic control to help bicycles cross major arterial roads; and * a distinctive look and/or ambiance such that cyclists become aware of the existence of the bike boulevard and motorists are alerted that the street is a priority route for bicyclists. These bikeway design elements are intended to appeal to casual, risk-averse, inexperienced and younger bicyclists who would not otherwise be willing to cycle with motor vehicle traffic. Compared to a bike path or rail trail, a bicycle boulevard is also a relatively low-cost approach to appealing to a broader cycling demographic. ==Features== A bicycle boulevard is generally marked with a sign at the beginning and the end of the bicycle boulevard.〔(Bicycle boulevard sign (Netherlands and Belgium) )〕 Also necessary for the road to be called a bicycle boulevard is coloring; in the Netherlands, the parts of the road where the cyclists ride on is marked in red (same color as used for segregated cycle facilities in the Netherlands). These sections of the road are called ''rabatstroken''.〔(Rabatstroken )〕 Motorists also ride on this section, yet also have a non-colored part of the road which they can drive on with one half (2 wheels) of the car when they wish to pass a cyclist.〔(Image of colored parts of the road and non-colored section )〕 Bicycle boulevards may use a variety of traffic calming elements to achieve a safe environment. This makes it difficult for motorists to use the street at a high speed. However, they do not block access to motor vehicles completely (i.e. using bollards) which would designate the route as segregated cycle facilities rather than a bicycle boulevard. Some bicycle boulevards have higher road surface standards than other residential streets, and encourage riders to use the full lane, encouraging parity between bicycles and motor vehicles. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「bicycle boulevard」の詳細全文を読む スポンサード リンク
