Transportation leadership you can trust. presented to FHWA “Talking Freight” Seminar Series presented by Lance Neumann Cambridge Systematics, Inc. August 2005 Freight Performance Measures
2
1 Overview Perspectives on Freight Performance Measures Freight Performance Measures in NCHRP 8-43 Selected Applications from Current Practice
3
2 Perspectives on Freight Performance Measures User needs versus system operator/planner needs Geographic scale Data and tools
4
3 Freight Performance Measures Different Stakeholders Use Different Measures Shippers Service cost, speed, reliability, security, visibility Carriers Business profitability return on investment States/MPOs Congestion mobility, safety, security, efficiency, economy, environment Gateways and Corridors Chokepoints related to equipment, infrastructure, operations, information, regulation
5
4 Data and Tools Adaptations of passenger transport tools Much data are in private sector Analytical tools and methods for freight analysis still developmental NCHRP 8-43 “Methods for Forecasting Statewide Freight Movements”
6
5 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
7
6 What Are States’ Primary Freight Policy and Analytical Needs? Need Response Frequency State Transportation Planning, including Multimodal Transportation Plans and/or Freight Plans High Project Prioritization, Statewide Transportation Improvement Program (STIP) Development High Modal Diversion AnalysisHigh Pavement, Bridge, and Safety ManagementMedium Commodity Flow Analysis (Types, Values, and Economic Importance of Freight Movement) Medium Rail PlanningMedium Trade Corridor and Border PlanningMedium Project Development or Design Needs (e.g., Forecasts and Loadings)Medium Bottleneck AnalysisMedium Terminal Access Planning for Ports, other Intermodal Terminals, and Grain or other Heavy Commodity Terminals Medium

7 Matching Performance Measures to Policy/Analytic Needs Policy/Analysis Needs Performance Measures Statewide Policy and PlanningFreight System Supply per “Demand Unit” Miles of Freight Routes with Adequate Capacity Dollar Losses due to Freight Delays Freight Mobility Index Modal DiversionCost per Ton and Ton-Mile by Mode Delay per Ton-Mile Traveled Average Shipment Time and Variability
9
8 What Tools Can be Used to Develop Freight Performance Measures? Performance Measure Direct Factoring of Flows Direct Factoring of O-D Table Trip Gen Trip Dist Mode Split Traffic Assign Administrative, Engineering, and Construction Cost/Ton-Mile (Owner Cost) Average Circuitry for Truck Trips of 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

9 Applications Evaluating 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
10 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
11 Applications Port 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
12 Strategies Evaluated Extended gate hours Empty container management Expanded on-dock rail New near-dock rail Shuttle train to Inland Empire
14
13 Conclusion Wide variety of freight related performance measures available Data/tools constrain measures that can be used Need to strengthen connection between measures used in public sector with shipper/carrier perspective
