Analysis Procedures Manual (APM)

About the APM

/ODOT/TD/TP/PublishingImages/APM.jpg The Analysis Procedures Manual (APM) provides the current methodologies, practices and procedures for conducting long term analysis of Oregon Department of Transportation (ODOT) plans and projects.

A major update of the manual is currently in progress. APM version 2 will incorporate methodologies from sources such as the 2010 Highway Capacity Manual (HCM) and the Highway Safety Manual (HSM). 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 HCM.


The APM has been updated. Please see the September 2014 Change Sheet for what has changed.

APM User Group

The Analysis Procedures Manual User Group (APMUG) is open to all interested parties either internal or external to ODOT. For information on APMUG, see the Analysis Procedures Manual User Group (APMUG) Guidelines. If you are interested in joining the group, contact Doug Norval.

Next meeting of the APMUG:

Date: Wednesday, October 8th, 2014
Location: Online 
Start time: 9:00 am (tentative)
End time: Noon (tentative) 
Suggestions for agenda topics and presenters are requested. Please submit any suggestions to Doug Norval.

Highway Capacity Manual

2010 Highway Capacity Manual methods shall be followed on all new projects except where other procedures are specified in the APM. Projects that were started prior to the 2010 HCM should continue to use methods of the HCM 2000. The APM Version 2 update will be providing further guidance on use of the new HCM 2010 methods as chapters are developed.
