Seattle Bus Volumes

A line feature layer derived from the Metro Transportation Network (TNET) King County. Each line segment represents a unique link in the King County transportation network. More information about TNET, including field metadata can be found in the King County GIS Catalogue. This layer is a simplified version of the TNET that is filtered for segments in Seattle where public bus transit service operates. Five fields are joined to the TNET layer representing the number of daily in-service buses that are scheduled to travel on the segment each weekday. Joined fields: CHANGE_NUM - Unique integer that identifies service change period. 157 = Fall 2024 TRIP_KIND_CD - S = service trip SCHED_DAY_TYPE_CODED_NUM - 0 = weekday DAILY_TRIP_CNT - The number of times per day the given t-link is traversed by buses meeting all criteria in the given row. ROUTES – Bus routes included in the DAILY_TRIP_CNT This data can be used to view scheduled in-service weekday bus volumes in Seattle by street segment and is reported in SDOT’s Annual Traffic Report. The current published layer represents bus volume data from the Fall 2024 service change (September 2024 – March 2025) and may be out of date with current service levels. Data will be refreshed annually with the update of the Annual Traffic Report. If you need more recent data, please contact King County. Maintained by Seattle Department of Transportation Refresh Cycle: Static, manually updated as required Contact: SDOT Transit and Mobility team本数据集为源自金县都会交通网络（Metro Transportation Network, TNET）的线状要素图层。每个线段代表金县交通网络中的一条唯一链路。有关都会交通网络（TNET）的更多信息（含字段元数据）可从金县地理信息系统目录（King County GIS Catalogue）获取。 本图层为TNET的简化版本，经筛选仅保留西雅图市内提供公共巴士通勤服务的路段。该图层额外关联了5个字段，用于表征每个工作日内，按计划行经对应路段的在役巴士每日班次总量。 关联字段详情如下： CHANGE_NUM：用于标识服务变更周期的唯一整数，其中取值157对应2024年秋季服务周期； TRIP_KIND_CD：取值S代表服务班次（service trip）； SCHED_DAY_TYPE_CODED_NUM：取值0代表工作日； DAILY_TRIP_CNT：符合当前行所有筛选条件的巴士，每日行经指定TNET链路的总次数； ROUTES：纳入DAILY_TRIP_CNT统计范围的巴士线路。 本数据集可按路段展示西雅图市内工作日在役巴士的计划运营流量，相关数据已收录于西雅图交通局（Seattle Department of Transportation, SDOT）年度交通报告。 当前发布的图层采用2024年秋季服务变更周期（2024年9月—2025年3月）的巴士流量数据，可能与当前实际服务水平存在偏差。本数据集将随年度交通报告的更新每年刷新一次。若需获取最新数据，请联系金县相关部门。 维护方：西雅图交通局（Seattle Department of Transportation, SDOT）；更新周期：静态更新，按需手动调整；联系方式：SDOT通勤与出行服务团队（SDOT Transit and Mobility team）
