Florida Department of Transportation (FDOT)’s Roadway Characteristics Inventory (RCI) Handbook has been developed as a guide for personnel responsible for performing business functions that maintain the strategic development and planning of transportation data for the Department and the system of record commonly referred to as RCI. This resource covers the following:

  • describes how RCI supports the business data requirements and users of the system
  • documents the processes for establishing and managing the location of roadway assets and multimodal travel ways
  • describes how to collect data and the related features and characteristics of those roadway assets and multimodal travel ways;
  • establishes data governance for RCI features and characteristics data collection; and
  • provides the data quality management processes that maintain the integrity of the data management system.

    The Transportation Data and Analytics (TDA) Office is responsible for the maintenance of this handbook and coordinates changes with other offices.  This handbook is used by FDOT personnel in the District and Central Offices who perform data collection in the field and in the office.
