Balancing Network Circuity and Density
We’re pleased to finally be operational with the latest optimizations to our freight flow. We implemented this latest round of network adjustments on Monday, January 11th. They are the latest in a series of high-impact changes that we’ve made to our network during the last two years. The changes adjusted the flow of freight in a few key corridors to run more direct paths where we have the density required to do so efficiently.
To make it easy to understand what we changed, we (thanks Olga) graphed the freight flows on Thursday, January 7th and Thursday, January 14th for the load plan legs that connect Houston, Texas and Burlington, Vermont.
The orange line shows the old flow. The size of the line is the total volume of freight travelling on that linehaul leg. We used to travel way out of the way and risked getting caught in the snow in the Midwest while moving freight from Texas to New England. Through analysis by our linehaul team, we were able to find the more direct blue route with high enough density to reduce the total number of miles that we drive. This path also helps avoid some of the winter weather that can threaten on-time service performance.
Hundreds of adjustments like this were made to our network last week. We’re excited by the positive impact that these changes will make to our service levels and cost structure. Enjoy!
