Overview
Perspectives on Freight Performance Measures
Freight Performance Measures in NCHRP 8-43
Selected Applications from Current Practice

Data and Tools
Adaptations of passenger transport tools
Much data are in private sector
Analytical tools and methods for freight analysisstill developmental
• NCHRP 8-43 “Methods for Forecasting StatewideFreight Movements”
6
Performance Measures in NCHRP 8-43
Toolkit for state-level freight forecasting
Performance measures tied to specific policy/planning and analytical needs
Performance measures are
• Forecastable
• Use tools in the toolkit

Matching Performance Measuresto Policy/Analytic Needs
Policy/Analysis Needs Performance Measures
Statewide Policy and Planning • Freight System Supply per “Demand Unit”
• Miles of Freight Routes withAdequate Capacity
• Dollar Losses due to Freight Delays
• Freight Mobility Index
Modal Diversion • Cost per Ton and Ton-Mile by Mode
• Delay per Ton-Mile Traveled
• Average Shipment Time and Variability

What Tools Can be Used to DevelopFreight Performance Measures?
Performance Measure
Direct Factoringof Flows
Direct Factoring of O-D Table
TripGen

Mode Split
Traffic Assign
Administrative, Engineering,and Construction Cost/Ton-Mile (Owner Cost)
Average Circuitry for Truck Tripsof Selected O-D Pattern
Average Travel Time from Facility to Major Highway, Rail, or Other Network
Delay per Ton-Mile Traveled (by Mode)
Dollar Losses Due to Freight Delays
Origin-Destination Travel Times(by Mode)
Percent of Person/Freight Trips Occurring within Peak Periods
Percent of Traffic on Regional Highway that is Heavy Truck

ApplicationsEvaluating Truck-Oriented Infrastructure Improvements
Multiregional freight planning program –San Joaquin Valley, CA
Traffic assignment linked to post-processor (IDAS)
Performance measures
• Delay by vehicle class
• Travel times for major freight center O-Ds
• Incident delay on freeways (reliability)
• Accidents by type and vehicle class
• Emissions by vehicle class
11
Strategies Evaluated
Package 1 – Upgrading east-west highways to freeways
Package 2A – Adding general purpose capacity
Package 2B – Truck lanes and truck bypass lanes
Package 3 – Low emission trucks for through trips
Package 4 – Improved access to major freight site
12
ApplicationsPort Access and Impacts
San Pedro Bay Ports Truck-Trip Reduction Strategies
Trip generation model and travel demand model results linked to spreadsheet post processor
Performance measures
• Port truck-trips
• Port truck-traffic by time period on I-710
• Port truck VMT
• Net port transportation emissions (truck and rail)
13
Strategies Evaluated
Extended gate hours
Empty container management
Expanded on-dock rail
New near-dock rail
Shuttle train to Inland Empire
