Word Problem

 

 

To determine the impact on Pocahontas County highway traffic, we have to look at the "before and after" of how these vehicles move through the local area specifically.

The Comparison

1. Before (Standard Landfill Operation):

   The three garbage trucks would travel from their collection routes directly to the local Pocahontas County landfill. This results in 3 trips on the county's roads heading toward the landfill site.

2. After (Transfer Station Operation):

   • The 3 garbage trucks still have to travel from their routes to the same location (now acting as a transfer station) to dump their loads.

   • 1 tractor-trailer then departs from that same location to haul the combined load out of the county.

---

The Math

• Initial local traffic: 3 vehicles (the garbage trucks).

• New local traffic: 3 vehicles (the garbage trucks) + 1 vehicle (the tractor-trailer) = 4 vehicles.

The Result

In this specific scenario, the consolidation event actually increases the number of heavy vehicles on the local Pocahontas County highway by 1 additional trip.

While the consolidation reduces long-haul traffic on the road to Greenbrier County, the local roads see a 33% increase in heavy vehicle frequency (from 3 to 4) because the tractor-trailer adds a new departure trip that didn't exist when the trash was simply buried on-site.

The Scenario:

Y'all know Uncle Silas over at the transfer station, right? He's got three ol' dump trucks – we'll call 'em Rusty, Dusty, and 'Lil Red – that spent the morning haulin' trash from all over the hollows. Now, Silas is a smart ol' bird, and he knows it's plumb foolish to haul three small loads all the way out to the big landfill in Greenbrier County. So, he has 'em all dump their loads right there at the transfer station, into one giant pile.

Then, here comes Big Rig Bob with his mighty eighteen-wheeler tractor-trailer. Silas gets his backhoe crankin' and scoops up all the trash from that big pile and loads it clean onto Bob's trailer. Bob buckles it all down tight and heads off, clear over to Greenbrier County.

The Question:

Now, you tell me this: By haulin' that trash this way, how much did Old Man Silas and Big Rig Bob change the amount of extra traffic on the long road to Greenbrier County? Think hard now!
