Analysis Procedures Manual

The Analysis Procedures Manual, or APM, provides the current methodologies, practices and procedures for conducting long term analysis of Oregon Department of Transportation plans and projects.

A major update of the manual is currently in progress. APM version 2 will incorporate methodologies from sources such as the current version of the Highway Capacity Manual and the Highway Safety Manual. As new chapters or sections of APM version 2 are completed, they will be published on this webpage, and APM version 1 will be modified to refer to the version 2 procedures.

The APM does not establish any accepted or preferred software. Any analysis software is acceptable as long as it is consistent with the current APM and Highway Capacity Manual.

Analysis Procedures Manual Version 1 - All chapters - 2MB

APM Version 2 (In Progress)
