Regional Proposed Bike Facilities

June 7, 2022 No Longer Updated Proposed Regional Bicycle and Pedestrian Facilities In the past, updates to the Regional Bike Facilities layers were biennial, to coincide with updates of the Bicycle and Pedestrian Master Plan. Going forward, updates will take place annually, though major projects will be added as they are opened, if needed. The Regional Bicycle, Pedestrian, and Trails Master Plan envisions a complete transportation system that supports healthy living and active communities where bicycling and walking are viable and popular travel choices in a comprehensive, safe, and convenient network. The proposed bike facilities layer is a comprehensive layer of bikeways planned by local agencies throughout the region. This data reflects potential bicycle & pedestrian facilities in order to help guide the development of a seamless and integrated regional bikeway network. Since these facilities are in various stages of planning, all may not be eventually built. On-street facilities are aligned to the Regional Centerline; off-street facilities have been added from jurisdiction submissions or digitized using imagery, and final alignments may not have been determined. Line segments represent potential future transportation facilities for pedestrian and/or bicycle use. The "class" field signifies level of use in the design. Class 1 designates a hard-surface multi-use trail suitable for bicycle and foot traffic. It is separate from facilities for motor vehicle traffic and meets CalTrans standards for width, signage, and surface. Class 2 designates an on-street lane for bicycles only. Lanes have striping and other markings to separate them from motor vehicle traffic. There are versions of class 2 lanes that are separated from traffic with painted areas for added security and visibility for riders. Class 3 designates an on-street route for bicycles only. Routes are marked by signage only; cyclists are expected to ride with the flow of traffic. Class 4 designates a buffered bike lane. Buffered bike lanes have have striping and other markings to designate them for bicycle traffic, but also by some form of upright buffer to separate them from motor vehicle traffic. Possible buffers include curbs, planters, parked cars, and pylons. A bike lane separated by paint only is a class 2, not a class 4. Class 0 is a SACOG-created designation to indicate informal trails of local or regional importance. The large majority of these are unpaved trails bridging gaps between other facilities, but some may be paved trails that do not meet the CalTrans width requirements for inclusion as a class 1 facility. Few, if any, informal trails exist in the planning phase. Updates will occur on a rolling basis as we review plans and learn about bike/ped facilities added to plans or removed from consideration.2022年6月7日 | 本数据集不再更新：拟建区域自行车与步行设施（Proposed Regional Bicycle and Pedestrian Facilities）。 过往，区域自行车设施图层的更新周期为两年，与《自行车与步行总体规划（Bicycle and Pedestrian Master Plan）》的更新节奏保持同步。今后，更新周期将调整为每年一次，但若有重大项目建成开放，可根据需要随时增补相关内容。 《区域自行车、步行与步道总体规划》旨在构建一套完整的交通系统，助力健康生活与活力社区建设，使骑行与步行成为覆盖全面、安全便捷的交通网络中切实可行且广受欢迎的出行选择。 拟建自行车设施图层是区域内各地方机构统筹规划的自行车道综合数据集。本数据用于展示潜在的自行车与步行设施，以辅助构建无缝衔接、一体化的区域自行车道网络。由于此类设施处于不同的规划阶段，并非所有项目最终都能落地实施。 路面内嵌设施与区域中心线对齐；路面外设施则源自各辖区提交的申报资料，或通过影像数字化绘制而成，最终的线路走向尚未确定。数据中的线段代表未来可供步行或骑行使用的潜在交通设施。 "class"字段代表设施的设计使用等级： - Class 1（一级）：硬质路面多用途步道，适用于自行车与步行交通，与机动车道完全分离，且在宽度、标识与路面标准上符合加州交通局（CalTrans）的规范要求。 - Class 2（二级）：专供自行车使用的路面车道，通过标线与其他标记与机动车流分隔。部分二级车道会增设涂装隔离区域，以提升骑行者的安全性与可见度。 - Class 3（三级）：专供自行车使用的路面路线，仅通过标识牌进行标注，骑行者需顺车流方向行驶。 - Class 4（四级）：带缓冲设施的自行车道，通过标线与其他标记划定为自行车专用道，同时通过直立式缓冲设施与机动车流分隔，缓冲设施可包括路缘、种植池、停放车辆与隔离柱。仅通过涂装与车流隔离的自行车道属于二级车道，而非四级。 - Class 0（零级）：由萨克拉门托区域政府委员会（SACOG）设立的分类，用于指代具有本地或区域重要性的非正式步道。此类步道绝大多数为未铺装路面，用于填补其他设施之间的通行空白，但也包含部分未达到一级设施加州交通局宽度标准的铺装步道。处于规划阶段的非正式步道极少，即便存在也为数不多。 本数据集将根据规划方案的审核进度，以及新增或不再纳入规划的自行车/步行设施相关信息，进行滚动更新。
