Prototype Draft - Strategic Measure_Street Conditions_v2.0

This dataset is collected & compiled by the Street & Bridge Operations division under the Public Works Department. The street network consisted of about 2525 miles of streets and just over 7863 lane miles of pavement in fiscal year 2019. Since many streets consist of multiple lanes, there are about three times as many lane miles as miles of streets. We report based on lane miles, rather than street miles in order to better capture the public's driving experience.

Data is collected by a contacted vendor, who drives the streets using a specially equipped vehicle that records the data used to determine street condition. The vendor drives every lane of every street in the city, covering about half of the city every year. Street condition is then classified as "Satisfactory" or "Unsatisfactory" based on national street engineering standards.

The measure's outcome reflects the ratio of satisfactory lane miles in the City's street inventory to the total number of lane miles in the City's street inventory. This measure is also a Key Performance Indicator for the Public Works Department, which means that it helps PWD constantly gauge the quality of City's street network, identify priority areas that need work, and take data-informed decisions on keeping the street network in serviceable conditions.

This dataset supports measure M.E.8 under the 'Mobility' outcome of Strategic Direction 2023.

本数据集由公共工程部门下属的街道与桥梁运营部门收集与编制。截至2019财年，街道网络包括约2525英里的街道以及7863英里多的铺装车道。由于许多街道由多个车道组成，车道英里数约为街道英里数的三倍。我们基于车道英里数进行报告，而非街道英里数，以便更准确地捕捉公众的驾驶体验。

数据由一家受委托的供应商收集，该供应商使用一辆特别装备的车辆在街道上行驶，记录用于确定街道状况的数据。供应商驾驶城市中每条街道的每个车道，每年覆盖约一半的城市。随后，根据国家街道工程标准，将街道状况分类为“满意”或“不满意”。

该指标的结果反映了城市街道库存中满意车道英里数与城市街道库存中总车道英里数的比率。该指标也是公共工程部门的关键绩效指标，这意味着它有助于PWD不断评估城市街道网络的质量，确定需要工作的优先区域，并基于数据信息就保持街道网络处于可服务状态作出决策。

本数据集支持战略方向2023年‘移动性’成果下的M.E.8措施。
