Chapter 13 - Traffic Forecasting and Analysis Concepts

13.1. Traffic Forecasting Process

This chapter explains the traffic forecasting process including how traffic analysis relates to roadway design.

During the course of the design process, the design engineer shall request traffic data for roadway capacity analysis to ensure that the functional requirements of the roadway are met. In addition, the traffic volumes are used to determine the pavement structure of the road. For Georgia DOT projects designed in-house, traffic volumes are supplied by the GDOT Office of Environment and Location (OEL). For consultant designed projects, the traffic volumes may be provided by GDOT, if available, or by the consultant as part of the scope of services in the consultant’s design contract.
