Bike Facilities

This line layer indicates streets within the City of Cambridge that have pavement markings or construction features that facilitate bicycle use. It also contains multi-purpose paths where bicycles can be used off the street. Explore all our data on the Cambridge GIS Data Dictionary. Attributes Name Type Details Description Street type: String width: 40 precision: 0 Same as "STREET" field from RoadCenterline layer, or name of mutli-use path entered manually ExistingFacility type: Double width: 8 precision: 38 3- or 4-digit code that corresponds to a bicycle facility type for existing facilities. Value is NULL if the segment is a PlannedFacility PlannedFacility type: Double width: 8 precision: 38 4- or 5-digit code beginning with "9" that corresponds to a bicycle facility type for planned facilities. Value is NULL if the segment is an ExistingFacility FacilityType type: String width: 255 precision: 0 The type of bicycle facility by category FacilityDetails type: String width: 255 precision: 0 Further details about the bicycle facility type on this segment, such as direction of travel, number of lanes, whether street is one-way or two-way street LaneMultiplier type: Double width: 8 precision: 38 The number of travel lanes along the bicycle facility line segment (1 or 2) to be used as a multiplier to arrive at a number for lane length LaneLengthFeet type: Double width: 8 precision: 38 Length in feet of all lanes of travel along the segment of the bicycle facility. Calculated by multiplying Shape_Length by LaneMultiplier YearAdded type: Double width: 8 precision: 38 The year the facility was built created_date type: Date width: 8 precision: 0 last_edited_date type: Date width: 8 precision: 0

本线要素图层展示剑桥市范围内所有带有便于自行车通行的路面标线或施工配套设施的街道，同时包含允许自行车脱离常规车行道行驶的多用途路径。可访问剑桥GIS数据字典（Cambridge GIS Data Dictionary）查看本机构全部相关数据集。

属性说明如下：
字段名 | 数据类型 | 宽度与精度 | 详细描述
Street | 字符串（String） | 宽度40，精度0 | 与RoadCenterline图层中的"STREET"字段内容一致，或为手动录入的多用途路径名称
ExistingFacility | 双精度浮点型（Double） | 宽度8，精度38 | 对应现有自行车设施类型的3位或4位编码。若该路段为规划设施（PlannedFacility），则此字段值为空
PlannedFacility | 双精度浮点型（Double） | 宽度8，精度38 | 以"9"开头的4位或5位编码，对应规划中自行车设施的类型。若该路段为现有设施（ExistingFacility），则此字段值为空
FacilityType | 字符串（String） | 宽度255，精度0 | 按类别划分的自行车设施类型
FacilityDetails | 字符串（String） | 宽度255，精度0 | 该路段自行车设施的详细补充信息，例如通行方向、车道数量、街道为单向还是双向通行
LaneMultiplier | 双精度浮点型（Double） | 宽度8，精度38 | 自行车设施路段的通行车道数（取值为1或2），用于作为乘数计算车道总长度
LaneLengthFeet | 双精度浮点型（Double） | 宽度8，精度38 | 该自行车设施路段所有通行车道的总长度（单位：英尺）。计算公式为Shape_Length乘以LaneMultiplier
YearAdded | 双精度浮点型（Double） | 宽度8，精度38 | 该设施的建成年份
created_date | 日期型（Date） | 宽度8，精度0 | 数据创建日期
last_edited_date | 日期型（Date） | 宽度8，精度0 | 数据最后编辑日期
