Transportation Statistics (TranStat)

The Transportation Statistics Office (TranStat) is the Florida Department of Transportation's central clearinghouse and principal source for highway and traffic data. The office gathers data directly through automated means and indirectly through district field personnel or others. TranStat provides tools and training to record, process, provide access, analyze, evaluate, and report these data. The office also publishes basic information documents and answers special requests for data inside and outside the agency.


Performance Measures, Analysis and Reporting

The System Performance Analysis Section has primary FDOT responsibilities in three areas: mobility performance measurement, highway performance analysis, and transportation systems analysis. The section oversees the development of FDOT’s Multimodal Mobility Performance Measures Source Book, the Department’s primary source of mobility performance measure results for the State of Florida. That information is used to meet state and local requirements and information desires. In the area of highway performance the section oversees the development of FDOT’s General Interest Highway Statistics Source Book, mileage reports and completes federal highway performance monitoring system requirements. The section is also responsible for the Department’s procedures and handbooks, and their implementation, related to urban boundaries, functional classification, roadway system designations and roadway jurisdictions/numbering/transfers.

Systems Support

The Transportation Statistics Office created and maintains the official FDOT linear referencing system of all roads in the Roadway Characteristics Inventory (RCI). It is also responsible for the production and maintenance of numerous maps (including the Federal Aid Highway maps), GIS data layers (shapefiles and geodatabases), and custom GIS tools. Other products include iView, Florida Traffic Online, and City-to-City Mileage.

Systems Traffic Modeling

Systems Traffic Modeling provides statistical traffic information for Florida's State Highway System. The Modeling Section develops and maintains computer models that are a mathematical tool for projecting passenger, freight and transit ridership. All models developed and applied in Florida are based on the Florida Standard Urban Transportation Model Structure (FSUTMS) which forms the foundation for long range transportation planning for FDOT and local transportation planning agencies. We work with Metropolitan Planning Organizations (MPOs), FDOT District Offices, FDOT Turnpike Offices, cities and counties to provide technical guidance, training, and assistance in the use of regional and local travel demand forecasting models. The Modeling section also supports other FDOT Divisions such as the Freight Logistics and Passenger Operations Office, Policy Planning, Traffic Engineering, Operations and Emergency Management.

Transportation Data

Transportation Data coordinates the collection of traffic data on all State highways and many highways not on the State Highway System. Depending on location, traffic data may include daily counts, vehicle classification, speeds, weight, directional factor, truck factor, and design hour factor. The Traffic Data Section operates a network of around 300 continuous traffic monitoring sites for daily transmittal to the Transportation Statistics Office. The Section also coordinates the collection of short-duration traffic studies at thousands of sites by District personnel. Traffic data is collected from January through December of each year, and then converted into annual statistics during the 1st quarter of the next year. The annual traffic statistics are posted to the website by April of each year.

Transportation Data Inventory

Transportation Data Inventory is designed to support the data needs of Department programs, databases and resources with identification, development, collection, analysis, distribution, and reporting of highway, freight, modal and motor carrier data as related to Florida’s multimodal transportation infrastructure and economy. These services will be used to support the routines, plans, reports, models and special studies of transportation systems and their utilization in order to assist the Department analyzing and producing information that supports the transportation freight and modal planning process ensuring the mobility of people and goods and economic prosperity.
