The purpose of this Handbook is to describe policies and procedures accepted by the Florida Department of Transportation (FDOT) and offer guidelines on principles and techniques for preparing project traffic required by various stages of the Project Development Process. The objective is to help standardize the traffic forecasting process that will result in consistent and defendable project traffic on all applicable transportation projects. The intended audience is transportation engineers and planners who develop project traffic for various highway projects for FDOT and its partner agencies in the state of Florida. This Handbook may be used by local governments and other agencies to review, accept, or approve project traffic developed for highway projects within their jurisdictions. This Handbook provides directions for Corridor Traffic Forecasting, Project Traffic Forecasting, and ESAL Forecasting. This handbook supplements the Project Traffic Forecasting Procedure Topic No. 525-030-120.
