Legal Speed Limits
收藏资源简介：
Legal Speed Limit (State and Local Roads) The maximum speed limit permitted under the provisions of the State Traffic Act and Regulations. Road speed limits are used to regulate the speed of vehicles and may define maximum (which may be variable), minimum, or no speed limit. These limits are indicated using traffic signs. Speed limits are set by the Commissioner of Main Roads Western Australia (Regulation 297 of the Road Traffic Code 2000) and enforced by national or regional police and/or judicial bodies. The speed limit displayed in this layer may not be current or accurate. The only enforceable source of speed limits is the road sign at the relevant physical location. Update Frequency Updates to the ArcGIS layer are triggered by changes in IRIS data and refreshed weekly. Disclaimer This layer shows the location of legal speed limits on all public access roads included in the Integrated Road Information System (IRIS) and is provided for informational purposes only.

法定车速限制（州级与地方道路） 本数据集依据《州交通法案及条例》的条文规定了允许的最高车速限制。道路车速限制用于规范车辆行驶速度，可定义最高限速（可为可变限速）、最低限速或无车速限制。此类限制通过交通标识进行标注。车速限制由西澳道路总局局长（Commissioner of Main Roads Western Australia）依据《2000年道路交通条例》第297条制定，并由国家或地区警方及/或司法机构执行。本图层中显示的车速限制可能并非最新或准确的；唯一具有法律效力的车速限制依据为对应物理位置处的道路标识。 更新频率 本ArcGIS图层的更新由综合道路信息系统（Integrated Road Information System, IRIS）的数据变更触发，每周刷新一次。 免责声明 本图层展示了纳入综合道路信息系统（IRIS）的所有公共通行道路上的法定车速限制位置，仅用于提供信息参考。请注意，您将在知识共享署名许可协议（Creative Commons Attribution Licence）的条款下访问本数据，该协议包含免责声明与责任限制条款。您知晓根据本许可协议提供的数据可能发生变更，且未必为最新或准确的信息。唯一具有法律效力的车速限制依据为对应物理位置处的道路标识。 重要使用须知 尽管本数据集可在知识共享许可协议的条款下使用，但西澳道路总局（Main Roads WA）不建议将其用于需要实时或精确车速限制数据的导航系统或应用程序。本数据集并非为运营用途而维护，可能无法反映当前生效的或标识标注的车速限制。西澳道路总局（Main Roads WA）不对本数据的使用（包括导航或合规工具中的使用）承担责任。 许可协议须知 根据本许可协议第3条，您在分享授权素材时需附带以下声明：西澳道路总局局长（Commissioner of Main Roads Western Australia）是本数据及授权素材的创作者与所有者，本数据将在知识共享署名许可协议（Creative Commons Attribution Licence）的条款下提供。该许可协议包含免责声明与责任限制条款。本数据可能并非最新或准确的信息。唯一具有法律效力的车速限制依据为对应物理位置处的道路标识。 许可协议：知识共享署名4.0国际许可（Creative Commons CC BY 4.0），链接：https://creativecommons.org/licenses/by/4.0/ 数据领域主管：数据规划与标准经理 数据保管人：数据与系统经理 运营数据主管：数据规划与标准经理 坐标系类型：地理坐标系（未投影，EPSG:4283 – GDA94） 参考资料：监管类标识 https://portal-mainroads.opendata.arcgis.com/datasets/3768b2d6a8fe4e3fa9c8b53197ba3b5e_22/ 如需了解监管类标识的含义，请参阅Panel_01_design_meaning属性。对于与车速相关的标识，可使用关键词“speed”对该属性进行筛选或搜索。 最后刷新时间：2026年4月20日 04:40 UTC
