AMPORFCommon Modeling Platform

Consolidated Travel Model Software Platform Development & Enhancement

Guy RousseauAtlanta Regional Commission

2014 AMPO Annual Conference

The Partners

• The Original 3 Partners:– Atlanta Regional Commission– Metropolitan Transportation Commission– San Diego Association of Governments

• The Additional 2 Partners:– Puget Sound Regional Council– San Francisco County Transportation Authority

Goals & Objectives• Reduce the overall costs of maintenance & development of innovative

new model components associated with isolated model implementations.

• Each MPO Partner currently uses a Coordinated Travel and Regional Activity Model Platform (CT-RAMP) Activity-Based Model (ABM).

• Combine the current CT-RAMP (programmed in Java) code branches developed for each MPO Partner into a consolidated trunk for use by each organization.

• The MPO Partners are only required to customize parameter and input files specific to their region.

• The consolidated code trunk will provide a robust platform to calibrate the model for each region.

• No changes to compiled libraries required to calibrate a model for a specified region.

History of Project

• ARC, MTC & SANDAG approached AMPO for project management in Summer of 2013

• AMPO’s Rich Denbow is Project Manager• RFP released in September 2013• 3 proposals were received• The 3 Original Partners met at MTC for proposals

reviews and consultants interviews• Synthicity was selected (www.synthicity.com)• Synthicity’s Paul Waddell is Project Lead• Project Kick-Off Meeting in February 2014
