Development of Statewide GIS-Based Features Inventory System Summary rept

摘要

The Arizona Department of Transportation (ADOT) has developed and implemented a component of a Maintenance Management System (MMS) called the Features Inventory System (FIS). With this system ADOT has the capability of tracking and maintaining an inventory of its highway features. These features can include anything found on or along a highway such as a guardrail, sign, lighting or other appurtenances. ADOT also needs to track the inventory of its highway features for the state legislative mandate in the maintenance appropriation (ARS 28-101) to provide level-of-service (LOS) conditions. These LOS condition measurements only have value if the population of the item, and how much of that population is in compliance, is known. The Feature Inventory System interfaces with the LOS System. In the past, ADOT used numerous methods of tracking the highway features. Early on, a mainframe system was put in place to track the inventory. This system is now antiquated and difficult to update, and Maintenance District offices have turned to other technologies including the use of Access databases and Excel spreadsheets. In order to standardize and bring all of the highway features inventory information into one place, ADOT's Maintenance Section has replaced the antiquated mainframe system with a browser-based system to track, maintain and account for its highway features. Utilizing funding from this research project, the FIS was built around a comprehensive features inventory database and is a core component of ADOT's MMS. This new system provides an application that is easier to utilize, and a database to store geographic information and other attributes of the highway features. This system also provides interfaces to other MMS modules, and is more robust than the mainframe system, incorporating an administrative function that allows key administrators to add new feature types, and define individual attributes for each feature type, as needed.
