Road Inventory 2014

The Road Inventory is a GIS-based asset management system for the state's highway transportation system. As such, its strengths are in describing the configuration and condition of public roads and rights-of-way. It is not designed to support route-finding (e.g., shortest path applications), nor is it designed to support geocoding (although in theory intersection-based geocoding could be set up on it). It is part of the official documentation of the state road system and is used to prepare the yearly Highway Performance Monitoring System (HPMS) report to the Federal Highway Administration (FHWA). It is a record of centerline and lane miles, which are the basis of state reimbursements to localities for road maintenance expenses (Chapter 90 funds).

道路资产清单（Road Inventory）是一套基于地理信息系统（Geographic Information System, GIS）的州级公路交通资产管理系统。正因如此，其核心优势在于能够精准描述公共道路及道路用地的布设状态与技术状况。该系统并非为路径寻路（如最短路径应用）设计，亦不支持地理编码（geocoding），尽管理论上可基于该系统搭建基于交叉口的地理编码功能。它属于州级道路系统官方档案的组成部分，用于编制每年向美国联邦公路管理局（Federal Highway Administration, FHWA）提交的公路性能监测系统（Highway Performance Monitoring System, HPMS）报告。该系统记录了道路中心线里程与车道里程，这些数据是州政府向地方拨付道路养护经费（第90章基金）的核心依据。
