Street Pavement Condition 2020

PCI 2020: Pavement Condition data collected in 2020, is used to report the overall pavement condition (PCI) at the network level and expresses the overall condition of a pavement segment by considering surface and structural distresses. Data was collected using a semi-automated process by an external contractor hired by the City. The data was collected from 1 lane for local roads and 1 lane in each direction for arterial roads. This PCI is averaged to reflect the overall condition for the entire width and length of the road segment. The City endeavours to collect pavement condition data every 3-4 years. The pavement distresses and condition ratings follow the American Society of Testing Materials (ASTM) D6433 standard. The data should be used for high level reference only. Ratings: Very Good: The asset is fit for the future. It is well maintained, in good condition, new or recently rehabilitated. Good: The asset is adequate. It is acceptable and generally within the mid-stage of its expected service life. Fair: The asset requires attention. The asset shows signs of deterioration and some elements exhibit deficiencies. Poor: There is an increasing potential for its condition to affect the service it provides. The asset is approaching the end of its service life and a large portion of the system exhibits significant deterioration. Very Poor: The asset is unfit for sustained service. It is near or beyond its expected service life and shows widespread signs of advanced deterioration. Limitations: 1. MRN roads are not included because they are collected by TransLink. 2. Data is only collected from 1-2 vehicular travel lanes, the asset condition on every lane for the entire road width was not collected. The pavement condition rating shown may not represent the full pavement width. ____________________________________________________________________________________________________________________________ MRN PCI 2020: MRN PCI data is provided by TransLink. This data was collected between 2020-2021 at a maximum interval of 50m, on 1 lane in each direction.

PCI 2020数据集：2020年采集的路面状况数据，用于汇报路网级整体路面状况指数（Pavement Condition Index，简称PCI），该指标通过综合考量路面表面病害与结构病害，表征单一路面路段的整体状况。本次数据由市政府聘用的外部承包商采用半自动化流程完成采集。本地道路仅采集单条车道的数据，干线道路则采集双向各一条车道的数据。通过对PCI值取平均，以反映该路面路段全幅全段的整体状况。市政府致力于每3至4年开展一次路面状况数据采集工作。路面病害判定与状况评级均遵循美国材料与试验协会（ASTM）D6433标准。本数据集仅可用于高层级参考。
评级标准如下：
极佳（Very Good）：资产可满足未来使用需求，维护状况良好，处于全新或近期翻新状态。
良好（Good）：资产性能达标，状态可接受，通常处于预期使用寿命的中期阶段。
一般（Fair）：资产需予以关注，已出现劣化迹象，部分结构存在缺陷。
较差（Poor）：其状况对服务能力的负面影响正逐步加剧，资产已接近使用寿命末期，系统内大面积区域出现明显劣化。
极差（Very Poor）：资产无法持续提供服务，已接近或超出预期使用寿命，大范围区域呈现严重劣化迹象。
局限性说明：
1. MRN道路未纳入本数据集，因其数据由TransLink采集。
2. 本次数据仅采集1至2条机动车行车道的数据，未覆盖路面全幅所有车道的资产状况，因此展示的路面状况评级未必能完全代表整条路面的全幅状况。
