and has identified major truck-freight bottlenecks.5 Using this source, the following methods for producing freight performance measures have been developed: Use of Multiple Unique Truck Positions to Measure Speed: Using this method, truck position pairs for individual/unique vehicles are matched, and a time/distance calculation is made to determine average travel rates. The end results are calculations along broad corridors (e.g., Interstate 10 from Jacksonville, FL, to Santa Monica, CA)

Such factors can play a role in meeting delivery windows and scheduling required hours of service and rest periods. Three methods are commonly used for determining reliability of travel: statistical range, buffer time measures, and tardy trip indicators:7 Statistical Range: This can be described as a Travel Time Window, Percent Variation, or Variability Index, all of which can be applied to freight movement.

ATA12 identifies the number of fatal crashes annually as a safety measurement for the entire industry and places the measure into two categories: • Total Annual Large-Truck Fatal Crashes • Large-Truck Fatal Crash Rate Per 100 Million VMT Such statistics are typically sourced from reports such as the FMCSA Large Truck Crash Facts 2005, which develops measures from data sources such as FARS, NHTSA's General Estimates System (GES) , and FMCSA's Motor Carrier Management Information System (MCMIS)

Waterborne Freight Performance Measures MARAD produces an annual Statistical Snapshot19 that provides nearly 20 categories of water-freight-related statistics. The statistics address freight volumes, ports of entry and export, commodity trends, numbers of ships and containers involved, measures of trade, measures of employment in the industry, and measures of the economics of waterborne shipping.

ports. It stressed that, to assess port operations, it needed to interview port officials, port labor representatives, shippers, ship operators, and truckers, and it had to assess the infrastructure related to highways, rail, water, and the intermodal transfer points between the modes.

Aggregate data are normalized to adjust for seasonal variations but do not provide granularity as to types of commodities shipped, or by origins and destinations. european union Transport policy for 2010 The European Union has not adopted freight performance measures per se but it has adopted firm goals that arise from table e.2.

It also proposed the acceleration of biofuels and hydrogen to achieve air quality and greenhouse gas emissions goals that have not been achieved so far by the mode-shift strategy.32 13 MARAD's commercial performance measures include the number of short sea demonstration projects; the number of innovations in ship building technologies; the number of innovations in environmental impact prevention; the number of innovations in marine/land-based linkages; and the amount of private investment in ship building. Its performance measures for commercial mobility focus specifically on its internal accomplishment of activities to support commerce, as opposed to focusing on the actual operations of the maritime system.
