The objective of this research was to develop a guidebook describing methods, data sources, and procedures for producing travel forecasts for highway project-level analysis. The guidebook evaluates and expands on currently used methods and tools to include appropriate data or information sources and system-level methods (ranging from readily available practices to advanced practices) to address a variety of project development purposes, needs, and impacts. The guidebook is intended to be used by transportation planning, operations, and project development staff to better support planning, design, and operations recommendations. 

The final products are available here.
