Table 3-16. Truck Trip Reliability as Indicated by Minimum and Maximum Travel Times between Selected City Pairs: January-March 2012
Intercity travel-time reliability is a key freight performance measure. It influences logistics, operational strategies, and load optimization. FHWA analyzed the truck trip reliability of 22 top freight origins and destinations. Travel time between San Diego and Los Angeles showed the greatest change, increasing nearly 55 minutes in the northbound direction and more than 88 minutes in the southbound direction. Other city pairs also showed large differences in travel-time reliability.
