TBWG Presentation Overview
Why is a POE performance measurement tool needed?
How was this new POE tool developed?
What is the new POE performance measurement tool?
How does the new tool work?
What are the applications for using the new tool?
Who benefits from using the new tool?
How should the new tool be used
WHY a new POE Performance Measurement Tool?
Problem statement: There is currently no standardized POE performance measurement tool that can:
Evaluate impacts of pre to post POE improvements
Provide standardized port to port comparisons
Provide standardized border to border comparisons
WHY a new POE Performance Measurement Tool?
Problem Statement: How can service level policy, service levels and port performance be conveyed in a consistent, meaningful, understandable and accurate manner for all POE’s? Time? Queue length? Real time or longitudinal data? Is there consistency of measurement? Is there consistency of understanding?
How was this new POE Tool Developed ?
Highway Capacity Manual (HCM) Level-of-Service Concept (LOS) Uninterrupted Flows / Interrupted Flows
Other applications of the LOS concept Transport Canada: ATB subsystem analysis
How was this new POE Tool Developed ?
MIT
What is the new Tool ? (A: An LOS approach)
LOS Criteria
A-F Service Level Categories
Service Policy Settings

LOS Algorithm Model (based on hourly traffic distributions)
Total vehicles(arrivals + queue)
How it Works | Setting LOS Policy Algorithms convert hourly
arrival data into LOS categories
LOS Framework: Policy Settings LOS Output: Trade-Off Analysis
How it Works | Trade-Off Analysis
How it Works | Pre to Post Improvement Analysis
LOS Decay (Pre and Post Investment)
pre-investmenttrigger pointLOS “D”
LOS gain post-investment
LOS would continue to decay without POE improvements
How it Works | Next Step in Concept Refinement
Modify algorithms to provide benefit-cost data
Pre-post LOS improvement scenarios Aggregation of delay, fuel and emissions

What are some LOS applications? (micro)
The LOS output provides: A snapshot for any or all 8,760 hours in a year Longitudinal analysis over a 20+ year planning horizon Capability to set service level standards and assess LOS policy Capability to evaluate PIL infrastructure or staffing levels Capability to evaluate various processing time scenarios Output generated by direction of travel Output generated by vehicle type
WHAT are some LOS applications? (macro)
A standardized POE performance measurement tool that can:
Evaluate impacts of pre to post POE improvements
Provide standardized port to port comparisons
Provide standardized border to border comparisons
Who benefits from using the LOS methodology ?
Transportation and border services agencies Trade-off analysis to determine optimal port improvements
Federal, State and Provincial funding agencies Standardized analysis for evaluating funding applications
Inland Ports | Logistics Interests Supports business case analysis to assess fluidity at POE’s
All Stakeholders Meaningful data on future port performance
WHERE can the LOS Methodology be Applied?
Top 20 POE’s: Canada-USA-Mexico
WHEN should the LOS Methodology be used?
Major POE planning studies / funding applications
Trade-off analysis for POE improvement scenarios
Evaluating the costs-benefits of POE improvements
Longitudinal analysis & monitoring POE performance
Responding to stakeholders on POE performance
Summary: Advantages of an LOS Approach at POE’s
A standardized approach for system-wide POE planning A concept that is user-friendly & easy to understand Predictive capabilities (20+ years) Ability to express positive measures of POE performance Ability to conduct multi-variant trade-off analysisAn efficient & cost effective tool for scenario testing Multiple beneficiaries and applications
A Final Word on the LOS Methodology for POE’s
Challenge: POE project delivery requires 6-10 years to complete a number of sequential planning and implementation stepsConceptual Planning, Functional Design, Final DesignTendering and Construction
Challenge: The bi-national POE context can involve input from up to 8 agencies to deliver an integrated infrastructure solution
Opportunity: The LOS methodology provides a common approach for all transportation and border services agencies to test, select and monitor POE performance improvement solutions that can include infrastructure improvements, technology deployment or staffing scenarios
