Traffic Analysis is the process of evaluating the effect of traffic demand and facility supply on the performance of a transportation infrastructure in relation to established goals and objectives of the facility. The Department developed the Traffic Analysis Handbook and the Project Traffic Forecasting Handbook to provide guidance and general requirements for uniform application of traffic analysis tools.
The FDOT’s Traffic Analysis Handbook provides guidance and general requirements for the uniform application of traffic analysis tools on roadway corridors, interchange, and intersection analyses. The techniques and accepted procedures for analyzing project traffic within the Florida State Highway System (SHS) are documented in this handbook. This handbook focuses on methods, tools, and documentation for traffic analysis. Additionally, the handbook guides traffic analysts, reviewers, and decision-makers through development of the documentation and deliverables necessary to complete the traffic analysis process.
The Project Traffic Forecasting Handbook is intended to provide planning guidance on principles and techniques for preparing project traffic estimates and required for Project Development and Environment (PD&E) studies, along with Resurfacing, Restoration and Rehabilitation (RRR) projects. In addition, it provides an overview of the methodologies and processes used to collect various types of traffic data and offer guidelines on how to analyze and evaluate the data and determine the most appropriate values to be used for project traffic development. The 2024 FDOT Design Manual (Chapter 913) requires traffic data consistent with the data used for pavement design to be included for each typical section. The Project Traffic Forecasting Handbook offers guidelines and techniques for Corridor Traffic Forecasting studies, Project-Level Traffic Forecasting studies, and 18-KIP Equivalent Single Axle Load (ESAL) studies.
