Next-day reliability

Tuesday, October 27th, 2009

When shipping freight, there are times when numbers do tell the story.  Holland leads the field with the most next-day service lanes in the region with 3,348 next-day lanes in and between these 21 states.

Our next-day service takes the kinks out of your supply chain. Orders placed on Monday morning can be shipped and delivered on Tuesday often before noon with standard service. Your customers will be delighted with how quickly products get to market.

Equally important is the next-day reliability you count on from Holland, a YRC company. We deliver over 97% on time against the most stringent next-day transit times in the region. The result? Production lines stay on schedule and retail inventory can be restocked–with confidence–based on demand.

Passenger and freight movement

Wednesday, June 3rd, 2009

Freight truck models develop highway freight truck rates by assigning an O?D table of freight truck flows to a highway network. The O?D truck table is produced by applying truck trip generation and distribution steps to existing and forecast employment and/or other variables of economic activity for analysis zones. This method involves estimating the O?D table directly using trip generation rates/equations and trip distribution models at the TAZ level. This is similar to the four-step passenger models. The mode choice step is eliminated since shipping freight truck trips are estimated directly without consideration of other possible modes for moving freight. The components required for this modeling technique include existing and forecast zonal employment data, methods to generate zonal freight productions and attractions by using freight truck trip generation rates, methods to generate truck O?D flows by applying trip distribution procedures to truck productions and attractions, and methods to assign the O?D freight truck flows to a highway network.

Freight truck models usually attempt to account for shipment of goods, including local delivery. Because these models are focused exclusively on the truck mode, they cannot analyze shifts between modes. Truck models are usually part of a comprehensive model that forecasts both passenger and freight movement and, consequently will often use a simultaneous assignment of truck trips with automobile trips.
