HPMS Peak Lanes

The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) HPMS peak lanes event polyline feature class represents the total number of through lanes available in the inventory direction during the peak travel period, while counter peak lanes capture the number of lanes open in the opposite (counter-peak) direction. These attributes help evaluate directional capacity, reversible lane operations, and congestion management strategies. The data are used by engineers, planners, and modelers to assess corridor performance, evaluate travel time reliability, and determine peak-hour operating characteristics. The dataset is reviewed and updated annually as part of ITD’s Highway Performance Monitoring System (HPMS) submittal to the Federal Highway Administration (FHWA). This layer is an export from Roads and Highways that represents only the active records within the LRS. These are current “working” records.

Metadata爱达荷州运输部（Idaho Transportation Department，ITD）的道路与公路路网线性参考系统（Linear Referencing System，LRS）下属的公路性能监测系统（Highway Performance Monitoring System，HPMS）高峰车道事件折线要素类，用于表征高峰出行时段内，清查统计方向上可用的总直行车道数；反向高峰车道（counter peak lanes）则统计对向（反向高峰）方向开放的车道数量。 此类属性可用于评估道路通行方向的通行能力、可逆车道运行状态以及拥堵管理策略。 工程师、规划师与交通建模人员可依托该数据集评估通道路段的运行效能，分析出行时间可靠性，并确定高峰时段的运行特征。 该数据集每年均会开展审核与更新工作，作为ITD向联邦公路管理局（Federal Highway Administration，FHWA）提交HPMS相关数据的组成部分。 本图层为从《道路与公路》系统导出的产物，仅包含LRS内的有效记录，即当前的"working"记录。 如需获取静态公开数据，请查阅存储于以下网址的记录：https://www.fhwa.dot.gov/policyinformation/hpms.cfm 本内容项为HPMS权威要素图层的子图层。元数据（Metadata）
