Progressive transportation planning
Shared decision making
Regional Congestion Management System (CMS)
FHWA admonishment

A New Day for CongestionPortland, Oregon
New university transportation center
Government and business collaborate: Cost of Congestion
METRO CMS roadmap RTP update “New Look:” 1 million
people by 2030 LRT and streetcar
additions
5
SAFETEA-LUA National University Transportation Center for Oregon
60 new university transportation centers Research on critical national transportation needs
and expand transportation workforce. $16 million for Oregon Research, education and technology transfer Advanced technology, integration of
transportation/land use and healthy communities Multidisciplinary, statewide, multimodal
6
SAFETEA-LUA National University Transportation Center for Oregon
Provide relevant research to assist local, state, and regional agencies in their work;
Expand the pool of highly talented students who choose transportation planning and engineering;
Build upon our collective efforts to make Oregon a place where innovation, creativity, and collaboration lead to sustainable communities.
7
The Cost of CongestionMETRO/Portland Business Alliance
Region’s economy is transportation dependent
Action needed to remain competitive As a trade hub, Portland largely
dependent on efficient transportation Businesses report congestion costs Failure to invest will bes costly Additional regional investment will pay off Has generated community conversations
8
Managing CongestionCongestion Management Process (CMP)
MPO over 200,000 population (ISTEA, TEA-21, SAFETEA-LU)
Systematic process for managing congestion that provides information on transportation system performance and alternative strategies for alleviating congestion and enhancing mobility.

10
Managing CongestionCongestion Management System (CMS)
Monitor and evaluate system, identify congestion causes, evaluate alternative actions, and evaluate benefits of implemented actions;
Measure extent of congestion and evaluate congestion reduction and mobility enhancing strategies;
Data collection and system performance monitoring;
Benefits of traditional/non-traditional congestion management strategies;
Implementation schedule, responsibilities, and funding; and
Periodic assessment of implemented strategies, in context of established performance measures.
11
Managing CongestionMETRO’s CMS Roadmap
Planning-oriented performance measures Planning for operations Roadmap:
1. Measure transportation system performance
2. Identify the causes of congestion3. Identify and evaluate alternative
actions4. Implement cost-effective
solutions5. Evaluate the efficiency and
effectiveness of implemented actions

Point to Point Off-Peak Travel Time Reliability (I-5 N)
Point to Point Peak-Hour Travel Time Reliability (I-5 N)
19
Transportation System Management and Operations (TSMO)
Optimize performance of existing infrastructure
MPOs can plan, promote and prioritize but not operate
METRO collaborates with city, county, state and transit operating agencies
2005 FHWA grant to demonstrate Regional Concept of Operations (RCTO)
Shared regional vision of operations First RCTO: traveler information
20
Next Steps and Concluding Remarks
Continue development of CMS Road Map
Add data sources to PORTAL Freight/classification data Transit AVL data Arterial performance Freeway incident data
Improve data quality Provide decision support for
transportation officials in the region Involve stakeholders and FHWA
