Overview

Perspectives on Freight Performance Measures

Freight Performance Measures in NCHRP 8-43

Selected Applications from Current Practice

Perspectives on Freight Performance Measures

User needs versus system operator/planner needs

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

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

14

Conclusion

Wide variety of freight related performancemeasures available

Data/tools constrain measures that can be used

Need to strengthen connection between measures used in public sector with shipper/carrier perspective
