Introduction
Transportation Infrastructure is critical to quality of life
• Roads, bridges and transit systems provide: – personal mobility
– transport of people and goods
– sustainability of communities
Value of Canada’s Public Transportation Infrastructure
(in $ billions)
Introduction
Pressures on transportation Infrastructure
– Aging and deterioration of assets
– Increasing demands on services
– Increasing loads on assets
– Limited resources: fixing old vs. building new
– New environmental requirements and regulations
– Demographic shifts
– Changing cost of energy
– Security concerns for some critical assets/services
Need for Objective-based Management
Framework
Address current knowledge gaps and needs:
• Large numbers of measures – hard to compare
• No clear definitions of objectives of performance assessment and management
• Subjectivity/limited accuracy of some performance measures
• Reliance on qualitative performance indicators for safety and
health-critical systems
• Lack of performance-based inspection of assets
• Inconsistent weighting of measures for tactical and strategic levels of decision-making
• No integration of performance assessment & management of different CPI systems
Can be used by different audiences: Policy and decision-makers, managers and users of CPI to:
• Assess current and future states of Canada’s CPI
• Assess future demands on CPI
• Identify common objectives
• Identify key performance indicators for assets and services
• Establish interdependencies between assets and services
Need for Objective-based Management
Framework
Support decision-making at project, tactical & strategic levels to: • Assess the state, performance and management of Canada’s CPI
• Integrate management of different systems
• Identify critical CPI systems in terms of public safety, health and security
• Identify best alternatives to improve performance of assets/services and mitigate demands
• Identify appropriate weights for different objectives for decision-making at tactical and strategic levels
• Optimize return on investment
• Integrate management of existing CPI systems with planning of new ones
• Contribute to the broad vision of sustainable communities

Building Blocks of Framework
Supports sustainability of communities
Objective-based performance assessment & management
Integrates the performance assessment of Assets and
Services provided by assets
Three tiers:
• Multi-Objectives: broad goals set by the
decision-makers and service providers for the CPI assets and services
• Assessment Criteria: Statement or principles to
assess the compliance with the objectives
• Performance Indicators: Quantitative and/or
qualitative measure of the performance of assets or services with regard to specific assessment criteria corresponding to the different objectives
Building Blocks of Framework
Objectives: broad goals set by the decision-makers and
service providers for the CPI assets and services • Why do we need assets and services?
• What do we expect from them?
Assessment Criteria: Statement or principles to assess
the compliance with the objectives • How to comply with the objectives ?
Performance Indicators: Quantitative and/or qualitative
measure of the performance of assets or services with regard to specific assessment criteria corresponding to the different objectives
Building Blocks of Framework
Why is infrastructure needed?
The OBJECTIVESof infrastructure services and assets are to support:
PUBLIC HEALTH PUBLIC SAFETY PUBLIC SECURITY MOBILITY (goods, people)
ENVIRONMENT QUALITY SOCIAL EQUITY ECONOMY
Infrastructure services are public services provided through infrastructure assets; in the context of this framework: moving goods and people, providing drinking water, collecting wastewater and
treating it before Its release into the environment
The ASSESSMENTof the performance of infrastructure services and assets in meeting the
Objectives is based on the following CRITERIA
HEALTH IMPACTS SAFETY IMPACTS SECURITY IMPACTS ECONOMIC IMPACTS
QUALITY OF SERVICE (to users) ACCESS TO SERVICE ADAPTABILITY
ENVIRONMENTAL IMPACTS ASSET PRESERVATION/RENEWAL/DECOMMISIONING
RELIABILITY OF SERVICE CAPACITY TO MEET DEMAND (present, future, extreme events, emergency)
The assessment of the PERFORMANCE of the services and assets is measured through the the following KEY INDICATORS
2 or more performance indicators can be aggregated to produce a performance index.
SERVICES key performance indicators ASSETS key performance indicators Influence
Collaborative Research Project:
• NRC-IRC
• NRTSI (National Round Table on Sustainable
Infrastructure) – Engineers Canada
• Infrastructure Canada (INFC)
• Phase 1: Duration: 15 months: Jan. 2008 – May 2009
Development Process
Organized International Workshop on Life Cycle
Performance and Management of CPI, July 2008
Established 2 committees to support the Model Framework
Limitations:
• Availability of data
• Lack of robust indicators for safety and health impacts
• Lack of indicators that measure social equity, economy
and environment protection
Implementation
Undertake survey to assess the current state of CPI assets
Expected Benefits
Advance state of knowledge in performance assessment and
management of transportation infrastructure
Foster collaboration between all stakeholders
Provide objective & harmonized Performance Measures to
improve assessment of infrastructure condition
Provide decision support to improve infrastructure performance
